Conjugated linoleic acid (CLA) comprises a group of C18 fatty acids containing conjugated double bonds and has been associated with potential anti-obesity and antitumor effects. In this study, 116 presumptive lactic acid bacteria (LAB) isolates were recovered from homemade Sichuan pickles. Primary screening identified 28 CLA-producing isolates, among which strains 7# and 31# showed the highest absorbance at 233 nm (A₂₃₃). CLA production by both strains was subsequently optimized and quantified using gas chromatography–quadrupole time-of-flight mass spectrometry (GC-Q-TOF). Under the optimized conditions, strain 31# produced 66.50 ± 3.80 μg/mL total CLA, including 52.70 ± 3.29 μg/mL c9,t11-CLA and 13.80 ± 0.51 μg/mL t10,c12-CLA. Strain 7# produced 26.79 ± 1.09 μg/mL total CLA, including 14.05 ± 0.49 μg/mL c9,t11-CLA and 12.74 ± 0.60 μg/mL t10,c12-CLA. Physiological, biochemical, and safety assessments showed that strain 31# outperformed strain 7# overall, supporting its use in further product development and mechanistic studies. Functional annotation using the COG database and pathway mapping with KEGG identified candidate genes encoding an enzyme associated with linoleic acid isomerization in both strains. Potential mechanisms underlying their different CLA-producing capacities were also examined, providing a basis for the selection and development of high-CLA-producing strains. Full article

Sheep milk and its fermented products are increasingly recognized as valuable functional foods due to their high nutritional value and the presence of biologically active compounds. The aim of this review was to summarize current knowledge on selected bioactive components of sheep milk and fermented sheep milk products, with particular emphasis on their potential application as functional food ingredients and the impact of technological processes on their biological properties. The review focuses on yogurts, kefirs, and cheeses, highlighting key bioactive compounds, including peptides, lactoferrin, conjugated linoleic acid (CLA), polar lipids, orotic acid, and probiotic microorganisms. Fermentation and maturation processes contribute to the formation and transformation of bioactive compounds, which may exhibit antioxidant, antimicrobial, antihypertensive, and immunomodulatory activities, as well as support gut health and metabolic regulation. The functional potential of sheep milk products depends on milk composition, microbial activity, and processing conditions. Despite promising findings, their wider application remains limited due to seasonal availability, low production scale, and insufficient knowledge regarding bioavailability and physiological effects. Further in vivo and clinical studies are required to confirm the health-promoting potential and practical applications of fermented sheep milk products as functional food ingredients. Full article

Tooth-bearing structures are commonly involved in the spread of various odontogenic lesions. Radicular and dentigerous cysts are among the most common odontogenic cysts, exhibiting significant variations in size and morphology within the jawbones. On the other hand, the influence of dental caries, periodontal diseases, and periapical lesions extends beyond tooth-bearing bone and also affects adjacent anatomical structures, especially the maxillary sinuses. In addition to untreated odontogenic lesions, treatment-related complications in the posterior maxilla may also disturb the sinus environment, particularly when oroantral communication is not recognized or adequately managed. The etiology of sinusitis is multifactorial; however, tooth-related infections are the primary cause of odontogenic sinusitis (ODS). Routine upper posterior tooth extraction may also become clinically significant when pre-existing sinus mucosal changes, close sinus floor proximity, or persistent oroantral communication are overlooked. When ODS is undiagnosed or overlooked on a classic computed tomography or a cone beam computed tomography (CBCT) scan, it is frequently inadequately managed by otolaryngological interventions alone; this leaves the underlying dental pathology unaddressed. Consequently, the utilization of CT/CBCT and close collaboration between dentists, oral surgeons, and otolaryngologists are essential for the successful management of these conditions. In advanced cases of ODS, isolated intranasal otolaryngological procedures are often insufficient. Comprehensive management relies on the elimination of all sources of odontogenic infection through endodontic therapy, dental extractions, and localized bone curettage. While the traditional Caldwell–Luc approach (CLA) is not commonly used nowadays, it remains an important surgical option in select cases, especially when infection spreads beyond tooth-bearing structures or soft tissue abscesses are present. This paper presents the radiological and clinical findings of two ODS cases with different etiologies and demonstrates how these findings influenced surgical planning. The aim is not to introduce the Caldwell–Luc approach as a novel technique but to illustrate its selective role when the direct treatment of the odontogenic source and oroantral defect is required.

Background/Objectives: Caseous lymphadenitis (CLA), caused by Corynebacterium pseudotuberculosis, is difficult to control on goat farms because of subclinical infection, abscess rupture, environmental contamination, and repeated herd-level exposure. This study evaluated a Korean inactivated CLA vaccine under commercial goat farm conditions and combined vaccination outcomes with farm-level bacteriological profiling. Methods: Goats from three commercial farms were allocated according to baseline CLA serostatus and vaccination status into seropositive vaccinated, seronegative vaccinated, seropositive non-vaccinated, and seronegative non-vaccinated control groups. Vaccinated goats received two intramuscular doses at weeks 0 and 4. Clinical signs, external abscess occurrence, growth performance, CLA-specific antibody responses, and abscess bacterial loads were monitored. Farm-level microbial profiles were assessed using culture, MALDI-TOF MS, and targeted PCR. Results: Baseline antibody classification showed strong agreement between the commercial CLA ELISA and the in-house whole-bacterial IgG ELISA, with a Spearman’s rho of 0.89 (p < 0.001) and 96.7% classification agreement. Vaccination induced CLA-specific antibody responses in both assays and was not associated with a persistent reduction in growth performance. External abscesses were observed only in baseline seropositive goats. Abscesses occurred in 1/30 vaccinated and 2/15 non-vaccinated seropositive goats, but the difference was not statistically significant (p = 0.254). Microbial profiling showed farm-dependent detection patterns. Conclusions: The vaccine induced CLA-specific antibody responses (immunogenicity) with acceptable tolerability. The exploratory abscess endpoint was underpowered, and clinical protection was not confirmed; larger studies are needed. Full article

Croscarmellose sodium (CCS) is a crosslinked cellulose-based superdisintegrant, widely utilized to enhance the disintegration and dissolution behavior of drugs from pharmaceutical solid dosage forms. In the present study, CCS was synthesized through controlled crosslinking of sodium carboxymethyl cellulose (CMC) by one-step synthesis and optimized using Response Surface Methodology (RSM) based on the Box–Behnken Design (BBD). The effects of four independent variables, namely isopropyl alcohol (IPA) concentration (70–100% v/v), reaction time (2–4 h), reaction temperature (50–70 °C), and concentration of crosslinking agent (CLA) (glycolic acid used as the CLA) (10–20% w/w of CMC weight), on swelling index (SI) and water retention capacity (WRC) of synthesized CCS were systematically evaluated. A total of 29 experimental runs, each representing a unique combination of reaction conditions generated by a three-level Box–Behnken Design (BBD) using Design-Expert^® software, were conducted to synthesize CCS samples. SI and WRC of each synthesized CCS sample were subsequently measured and used to develop statistically validated predictive models and identify the optimal synthesis conditions. The successful formation of croscarmellose sodium was critically confirmed by Fourier Transform Infrared (FTIR) spectroscopy. Analysis of variance (ANOVA) demonstrated that the developed models were statistically significant, with good predictive capability for both swelling index and water retention responses. A quadratic model adequately described the swelling index (R² = 0.9041, adjusted R² = 0.8083, p < 0.0001), whereas a linear model was selected for WRC (R² = 0.6112, adjusted R² = 0.5463, p < 0.0001). Reaction time and CLA concentration exhibited substantial influence on the functional properties of the synthesized CCS compared to other factors. The optimized synthesis conditions were identified as 93.23% IPA concentration, 4 h reaction time, 70 °C reaction temperature, and 10% CLA concentration. Under these conditions, the predicted swelling index and water retention capacity were 7.529 mL/g and 443.85%, respectively. Response surface analysis further revealed significant interaction effects among the synthesis variables, particularly between IPA concentration and reaction time. The findings of this study demonstrate that RSM-BBD is an effective statistical approach for optimizing cellulose-based superdisintegrant synthesis and provide valuable insights into the structure–property relationships governing the hydration and swelling behavior of CCS. The optimized CCS synthesized in this research thus shows potential for application as a high-performance pharmaceutical superdisintegrant in immediate-release tablet formulations. Full article

The peripartum period in prolific ewes is associated with increased metabolic demands, and dietary lipid supplementation may increase the energy density of the prepartum diet. This study evaluated the effects of prepartum supplementation with alternative lipid matrices on the physicochemical characteristics and comprehensive fatty acid (FA) profiles of mature and transitional sheep milk. Thirty-two pregnant Olkuska ewes were randomly assigned to four cohorts (n = 8/group): Control (basal diet), flaxseed oil (low n-3/high n-6 variety; FO), black soldier fly larvae oil (BSFL oil), and Mix oil (2:1 ratio of FO to BSFL oil). Dietary treatments exerted no significant effects (p > 0.05) on transitional milk composition or lipid quality indices. In contrast, in mature milk, BSFL oil supplementation significantly increased milk fat content (6.09%) compared to the Control group (4.70%; p < 0.01). Furthermore, all oil treatments significantly reduced total saturated FAs (p < 0.01), while the BSFL oil and Mix oil supplementation significantly increased the monounsaturated FA fraction (p < 0.01). The differences, particularly the increase in cis-9, trans-11 CLA concentration and the significant reduction in both the atherogenic and thrombogenic indices (p < 0.01), were observed exclusively in mature milk. These findings suggest that the combination of sustainable insect lipids with high-linoleic plant oils may represent a viable strategy to transform sheep milk into a functional food with potential cardiovascular health benefits for consumers. These findings additionally indicate that prepartum lipid supplementation may exert a persistent carry-over effect into early lactation, influencing the fatty acid composition of mature sheep milk.

Probiotic strains with multifunctional skin-beneficial properties represent promising candidates for next-generation cosmetic ingredients. In this study, a systematic stepwise screening strategy was applied to an in-house bacterial library comprising 302 isolates to identify candidates with antioxidant, anti-inflammatory, antimicrobial, wound-healing, and skin barrier-supportive activities. From this library, 33 strains were selected based on preliminary assessments and subjected to comprehensive in vitro evaluation. Cell viability and cytotoxicity assays confirmed the safety of all selected strains in RAW264.7 macrophages and HaCaT keratinocytes. Several strains exhibited strong DPPH radical scavenging activity and significantly inhibited nitric oxide production in LPS-stimulated macrophages. Among the selected candidates, Lacticaseibacillus rhamnosus DM073 demonstrated the most potent anti-inflammatory activity, whereas Lactiplantibacillus plantarum DM043 exhibited the greatest wound-healing capacity. All five selected strains displayed antimicrobial activity against Cutibacterium acnes. Furthermore, selected strains, particularly Lactiplantibacillus plantarum DM175 and Ligilactobacillus salivarius DM079, enhanced the expression of skin barrier-related genes, including zonula occludens-1 (ZO-1), occludin (OCLN), claudin-1 (Cla-1), and filaggrin (FLG), and partially restored their expression under TNF-α/IFN-γ-induced inflammatory conditions. Selected strains also reduced the expression of inflammatory chemokines in stimulated keratinocytes. Collectively, these findings demonstrate that the selected probiotic strains possess complementary multifunctional activities associated with skin health. In particular, DM073 exhibited superior anti-inflammatory activity, DM043 showed strong wound-healing potential, and DM175 demonstrated remarkable skin barrier-supportive effects. These strain-specific properties support their potential application in the development of probiotic-derived postbiotic cosmetic ingredients for skin soothing, barrier reinforcement, skin recovery, and microbiome-friendly skincare formulations. Further studies are warranted to evaluate their efficacy and safety in advanced skin models and clinical cosmetic applications. Full article

Background: Candida auris has emerged globally as a multidrug-resistant fungal pathogen responsible for healthcare-associated outbreaks and invasive infections. Whole-genome sequencing studies have demonstrated the existence of genetically distinct clades that differ in geographical distribution, antifungal resistance patterns, virulence traits, and outbreak potential. Objectives: This study aimed to evaluate the performance of the ClaID clade identification PCR system among clinical Candida auris isolates collected in İstanbul, Türkiye, and to investigate the clade-associated molecular profiles of circulating isolates. Methods: Forty-four clinical C. auris isolates were analysed using the auris universal sequence (AUS) assay and clade-specific sequence assays (CSS1–CSS5). PCR amplification results were interpreted according to the ClaID framework. Results: AUS amplification was detected in 41/44 isolates (93.2%). CSS1 amplification was observed in 39/44 isolates (88.6%), indicating a predominance of Clade I-associated molecular profiles within this regional İstanbul isolate collection. No amplification was detected using CSS2, CSS3, CSS4, or CSS5 assays. Three isolates were AUS-negative and five isolates did not yield CSS1 amplification despite repeated testing. Conclusions: The findings suggest that the majority of analyzed clinical isolates from İstanbul exhibited Clade I-associated molecular profiles rather than definitive WGS-confirmed clade assignments. This study provides one of the first field evaluations of the ClaID system in a Turkish clinical isolate collection and contributes regional molecular epidemiological data regarding PCR-based clade-associated profiles of C. auris in Türkiye.

Plant-pathogenic bacteria threaten crop productivity and quality, yet chemical options remain limited compared with those for fungal and oomycete diseases. Current management relies mainly on copper bactericides, limited antibiotics, induced-resistance agents, biocontrol and resistant cultivars. However, copper and streptomycin resistance, efflux-mediated multidrug tolerance and rapid pathogen adaptation have weakened these strategies. Target-oriented research provides a framework for exploring agricultural antibacterials, anti-virulence agents, anti-colonization strategies, resistance sensitizers and host-resistance interventions, but many of these approaches remain conceptual, model-system, greenhouse or medical-bacteriology-derived rather than proven field solutions. This review classifies bacterial control targets into two interconnected groups: growth-essential targets, including peptidoglycan biosynthesis, membrane/envelope systems, nucleic-acid processes, protein synthesis, metabolism, nutrient transport and cell division; and anti-virulence/anti-adaptation targets, including secretion systems, quorum sensing, biofilms, motility, adhesion, cell-wall-degrading enzymes, tolerance systems, oxidative-stress responses and host susceptibility factors. Using “Candidatus Liberibacter asiaticus” (CLas) as a case study, genome annotation and infection-stage transcript-abundance data prioritized Sec-dependent secretion, outer-membrane/surface proteins, Bam assembly, nutrient transporters, Clp proteostasis, redox adaptation and core cellular processes as candidate target classes. Envelope-associated, secretion/anti-virulence, nutrient-acquisition and stress-sensitization modules may represent potential directions for downstream validation, but CLas candidates remain hypothesis-generating priorities requiring validation for essentiality, conservation, druggability, delivery feasibility, crop safety and field performance.

Background: Marathon running triggers a robust systemic inflammatory response. Whether habitual dietary fat composition modulates pre-race cytokine concentrations or the magnitude and recovery of the exercise-induced inflammatory response remains unknown. Methods: Thirty-one recreational marathon runners (58.1% female; mean age 38.4 ± 10.2 years) completed the Diet History Questionnaire III to assess habitual dietary fat intake—including chain-length-specific SFA, MFA, PFA, trans fatty acids, and CLA—over the preceding three months. Circulating IFN-γ, IL-1β, IL-4, IL-6, IL-10, and TNF-α were measured pre-race, immediately post-race, and 48 h post-race. Repeated measures ANOVA examined cytokine changes; multivariable regression models estimated fat–cytokine associations adjusted for 11 pre-specified covariates, with Benjamini–Hochberg FDR correction applied across all models. Results: IL-6 rose markedly post-race (p < 0.001, generalized η² = 0.615) before returning to pre-race levels by 48 h. IL-10 followed a similar trajectory (p < 0.001, generalized η² = 0.346). TNF-α showed a borderline non-significant trend (p = 0.056); IFN-γ, IL-1β, and IL-4 did not change significantly. MFA 20:1 was positively associated with IFN-γ concentrations at 48 h post-race (β = 13.66; 95% CI: 8.94, 18.38, p < 0.01, q = 0.04) and TNF-α (β = 9.14; 95% CI: 6.43, 11.86, p < 0.01, q = 0.02). Conclusions: Habitual intake of the long-chain monounsaturated fatty acid 20:1 was positively associated with IFN-γ and TNF-α at 48 h post-race. This pattern, emerging specifically at the 48 h post-race phase, suggests that the post-race period, once acute exercise-induced signaling has subsided, may be a window in which habitual dietary fat quality is most detectable in relation to circulating cytokines. Habitual fat quality may warrant consideration in future endurance recovery nutrition research. This exploratory finding calls for replication in larger cohorts. Full article

The study investigates whether cultivated land abandonment (CLA) reflects structural transformation or an intensifying crisis. CLA is defined as land that has remained uncultivated for a minimum of two consecutive years, with the exclusion of land that is subject to deliberate programs such as the “Grain-for-Green” initiative. Utilizing the China Land Cover Dataset and a moving-window approach, we conducted a comprehensive analysis of spatiotemporal patterns across 2847 Chinese counties from 1992 to 2022. The research employed OLS, Tobit, high-dimensional fixed effects and instrumental variable regressions. The findings of the present study indicate an annual average abandonment rate of 2.3995%, with 12.3649% of cropland abandoned at least once and 9.2028% reclaimed, suggesting a fragile equilibrium. The Huang-Huai-Hai region and Northeast China’s plains emerged as low-abandonment clusters. Cropland fragmentation was found to trigger abandonment, while a higher ecological land ratio significantly exacerbates CLA. Rural labor migration and urbanization drive cumulative abandonment, worsened by the COVID-19 pandemic. Effective governance requires context-specific interventions that address key constraints and integrate land reuse into sustainable rural development frameworks. The research methods and theoretical mechanisms presented offer a reference for balancing food security, rural revitalization, and ecological sustainability worldwide. Full article

Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus (CLas) and vectored by Asian citrus psyllid (Diaphorina citri), remains a major constraint to sustainable citrus production. In Florida, individual protective covers (IPCs) have been adopted as an effective psyllid exclusion tool by shielding young trees from this vector of the phloem-dwelling bacterium CLas. Brassinosteroids (BRs), a class of plant steroid hormones, are being explored as a treatment to mitigate HLB and are approved for commercial use in the state. We investigated the effect of IPCs combined with homobrassinolide (HBr) applied as a foliar spray on CLas titer, canopy volume, tree growth, yield, fruit quality, and defense-related gene expression of the salicylic acid (SA) pathways in ‘Tango’ mandarin grafted on sour orange (SO) or US-942 rootstocks. After being covered with IPCs in the field for three years, trees were subjected to monthly foliar application of HBr upon IPC removal. The experiment included four treatment groups: trees with IPC and HBr spray (IPC HBr+), IPC without HBr (IPC HBr-), no-IPC with HBr (no-IPC HBr+), and no-IPC without HBr (no-IPC HBr-). IPCs effectively delayed bacterial infection for six to nine months after IPC removal, maintaining higher cycle threshold (Ct) values (lower CLas titers) than in no-IPC trees, confirming the protective effect of IPCs against early CLas colonization. The combination of IPCs and HBr spray significantly enhanced canopy volume, particularly in trees grafted on SO. This effect was sustained over one year and was consistently greater in IPC HBr+ trees than in IPC HBr- and no-IPC HBr+ or HBr- trees, suggesting a synergistic effect of the combined therapy on enhancing tree growth. The tree height and trunk diameter were primarily improved by IPC, regardless of HBr treatment. IPC-treated trees exhibited significantly greater height and trunk diameters (scion and rootstock) than no-IPC trees across one or both rootstocks, indicating that IPCs alone contribute to these horticultural growth improvements. IPC trees also showed reduced preharvest fruit drop compared to the no-IPCs trees, resulting in higher yields, with additional gains observed in IPC HBr+ trees on SO. Fruit quality attributes, including °Brix, titratable acidity, peel color, and size, did not differ significantly among treatments. Importantly, gene expression analysis revealed early and sustained upregulation of key SA pathway genes in IPC HBr+ trees, indicating that HBr effectively activated systemic acquired resistance (SAR), particularly on SO rootstock. This study highlights the complementary roles of IPCs and HBr in the management of HLB. While IPCs provided essential early protection against CLas and promoted long-term horticultural growth, HBr enhanced early canopy development, activated host defense mechanisms, and enhanced yield. The integration of both approaches offers a sustainable and effective strategy to protect young citrus trees, delay CLas infection, and improve tree health and productivity under endemic HLB.

In recent years, physiological signal-based biometrics has gained increasing attention due to its resistance to spoofing attacks, suitability for continuous authentication, and compatibility with wearable devices. This study investigates a multimodal biometric framework based on three physiological signals: galvanic skin response (GSR), electrocardiogram (ECG), and photoplethysmography (PPG). Although GSR has demonstrated promising performance in emotion recognition and animal recognition studies, it remains relatively underexplored in biometric human recognition applications compared with ECG and PPG. As a non-invasive signal that can be easily acquired through simple skin contact, GSR offers several advantages, including low-cost sensing, ease of integration into wearable devices, user convenience, and suitability for continuous monitoring. To address this gap, the proposed framework combines features extracted from ECG, PPG, and GSR signals and employs machine learning algorithms for human recognition. The approach was evaluated using two publicly available datasets, CLAS and MAUS. Experimental results demonstrate that multimodal fusion significantly enhances recognition performance, achieving accuracies of 97% and 99% on the CLAS and MAUS datasets, respectively, with the K-Nearest Neighbors (KNN) classifier. These findings highlight the potential of integrating GSR with ECG and PPG signals to develop biometric systems for wearable and continuous authentication applications. Full article

Six lactic acid bacteria isolated from São Jorge PDO cheese were characterised for technological, safety, antimicrobial, and probiotic properties. All isolates fermented a broad range of carbohydrates and lacked lipolytic activity, while SJC115 and SJC119 showed proteolysis. Safety profiling (γ-haemolysis, no DNase or gelatinase activity, and generally favourable antibiotic susceptibility) is promising, but tetracycline resistance warrants caution and genomic confirmation. L. paracasei and L. brevis isolates inhibited a wide range of foodborne pathogens (Listeria monocytogenes, Escherichia coli, Pseudomonas aeruginosa, Salmonella enterica, Bacillus spp.) and spoilage fungi (Penicillium and Aspergillus spp.). Notably, two isolates (SJC117 and SJC120) exhibited antibacterial activity in neutralized cell-free supernatants, indicating putative bacteriocin-like inhibitory substances (BLIS). The isolates survived intestinal conditions above the probiotic threshold, yet only SJC117 and SJC120 tolerated gastric acidity (pH 2.5, 1 h) with >5 log CFU/mL. Despite low hydrophobicity, strains showed good autoaggregation and pathogen coaggregation. All isolates produced exopolysaccharides (EPS) and angiotensin-converting enzyme (ACE) inhibitory peptides, whereas some exhibited moderate conjugated linoleic acid (CLA) production and glutamate decarboxylase (GAD) activity. L. paracasei SJC117 stood out by combining BLIS/antifungal activity, superior gastric tolerance, and an exceptional bioactive profile, making it a promising candidate for biopreservation and functional food applications that warrants further in vivo validation to confirm its efficacy and safety.

Mycobacterium abscessus subsp. massiliense (Mabs) is an emerging nontuberculous mycobacterium associated with difficult-to-treat infections due to intrinsic antimicrobial resistance, intracellular persistence, biofilm formation, and limited responsiveness to currently available therapeutic regimens. In this context, adjuvant strategies targeting iron-dependent metabolic pathways and metal homeostasis may enhance the efficacy of conventional antimicrobials. This study investigated deferoxamine (DFO), a clinically approved iron chelator, as a potential adjuvant against Mabs using integrated in vitro and in silico approaches. Cytocompatibility was assessed using an MTT assay in RAW 264.7 macrophages and a hemolysis assay in human erythrocytes. Antimicrobial activity was evaluated through minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assays, while interactions with clarithromycin (CLA) and amikacin (AMK) were assessed using the checkerboard method. Effects on virulence-associated phenotypes were examined through biofilm formation assays and protein quantification in extracellular vesicle-enriched fractions. Intracellular activity and modulation of inflammatory mediator gene expression were investigated in Mabs-infected RAW 264.7 macrophages through colony-forming unit (CFU) recovery and reverse transcription quantitative polymerase chain reaction (qPCR). DFO exhibited low cytotoxicity and negligible hemolytic activity under the tested conditions. Direct antimicrobial testing revealed a predominantly bacteriostatic profile (MIC = 9.75 µg/mL; MBC > 10 mg/mL), whereas checkerboard analysis suggested a synergistic interaction with CLA (FICI = 0.047), which requires further confirmation by time-kill or CFU-based combination assays. Furthermore, DFO reduced biofilm biomass, decreased protein levels in vesicle-enriched fractions, lowered intracellular bacterial burden, and modulated cytokine gene expression in infected macrophages. Molecular docking, ADME/Tox, and PASS analyses generated exploratory hypotheses regarding potential molecular interactions and pharmacological properties. Overall, these findings support DFO as a promising experimental adjuvant candidate for further investigation against Mabs, particularly in combination with clarithromycin. However, confirmation of a putative iron-restriction-associated mechanism and its translational relevance will require validation in additional clinical isolates, iron-rescue experiments, mature biofilm models, and in vivo studies.
