Q Fever is a zoonosis caused by Coxiella burnetii that affects domestic and wild ruminants, leading to reproductive disorders. In humans, the disease can manifest with acute and chronic clinical manifestations. Veterinarians, as healthcare professionals in close contact with animals, serve both as the first line of defence in preventing infection at the animal–human interface and as an important sentinel group for the rapid detection of outbreaks. The aim of this study was to assess the knowledge, perception, and attitude of veterinarians in Southern Spain regarding Q Fever. To this end, an online survey was designed, validated, and conducted among veterinarians in the province of Malaga, with a final participation of 97 individuals, predominantly from the private sector (clinic, livestock, agri-food, etc.). The data obtained reflected a general lack of knowledge about the disease, particularly concerning its epidemiology and infection prevention. Regarding perception and attitude, a significant percentage of respondents stated they did not use protective equipment when handling susceptible animals and only sought information about the disease in response to outbreak declarations. The study emphasised the significance of promoting training in zoonotic diseases during and after graduation, the relevance of official channels in occupational risk prevention, and the utility of epidemiological surveys as a tool to identify and address potential gaps in knowledge related to this disease.

Brucellosis is caused by Brucella spp.; it can result in fetal loss and abortion, resulting in economic losses and negative effects on human health. Herein, a cross-sectional study on the epidemiology of Brucella spp. in aborted livestock in Ningxia from 2022 to 2023 was conducted. A total of 749 aborted tissue samples from 215 cattle and 534 sheep were collected from farmers who reported abortions that were supported by veterinarians trained in biosecurity. The samples were analyzed using qPCR and were cultured for Brucella spp. when a positive result was obtained; the samples were speciated using AMOS-PCR. MLST and MLVA were employed for genotype identification. The results demonstrated that 8.68% of the samples were identified as being positive for Brucella spp. based on qPCR results. In total, 14 field strains of Brucella spp. were subsequently isolated, resulting in 11 B. melitensis, 2 B. abortus, and 1 B. suis. being identified via AMOS-PCR. Four sequence types were identified via MLST—ST7 and ST8 (B. melitensis), ST2 (B. abortus), and ST14 (B. suis)—with ST8 predominating. Five MLVA-8 genotypes and seven MLVA-11 genotypes were identified, with MLVA-11 GT116 predominating in livestock. Thus, at least three Brucella species are circulating in aborted livestock in Ningxia. This suggests a significant risk of transmission to other animals and humans. Therefore, disinfection and safe treatment procedures for aborted livestock and their products should be carried out to interrupt the transmission pathway; aborted livestock should be examined to determine zoonotic causes and targeted surveillance should be strengthened to improve the early detection of infectious causes, which will be of benefit to the breeding industry and public health security.

This study explores equine veterinarians’ clinical practices regarding mucocutaneous tumors, based on a survey conducted among members of the Portuguese Association of Equine Veterinarians, and examines their perceptions of owner and buyer concerns regarding these tumors. Veterinarians expressed significantly greater concern about squamous cell carcinoma (SCC) during routine examinations (p < 0.001) compared to sarcoids and melanomas. Concern over sarcoids was significantly greater during pre-purchase evaluations compared to routine clinical exams (p = 0.03). For melanomas, a trend toward increased concern in pre-purchase evaluations compared to routine examinations was observed (p = 0.07). There was a statistically significant association between the use of histopathology and the type of tumor (p < 0.001). Histopathology was performed less frequently in cases of melanoma compared to other tumor types. The cost was the main reason for not performing histopathology. During pre-purchase exams, buyers appeared to show greater concern regarding the presence of sarcoids (p = 0.001) and melanomas (p = 0.002) than regular owners. This study highlights the need to bolster training and education in equine oncology for veterinarians and owners to promote better diagnostic and therapeutic practices. Full article

Soft skills such as client-oriented communication, leadership, and teamwork skills are essential for veterinary clinicians. However, they are rarely addressed in the academic curriculum of most veterinary schools. Role-playing has been previously used to train and evaluate communication skills in veterinary students, but leadership and teamwork are difficult to implement in this methodology. In this study, we designed a novel role-playing activity where groups of undergraduate veterinary students faced simulated pre-planned clinical consultations portraying different roles in a hierarchically structured group (leader, two veterinarians, and one client). We tested the performance of the participants before and after receiving a focused lecture on soft skills. While the overall performance of the students in veterinary roles was significantly better after the lecture, the number of mistakes related to leadership did not significantly vary. Students rated the role of leader consistently lower than the rest. Participants considered that this novel design was useful to train and evaluate these competences. Hierarchically structured role-playing is a suitable tool to improve soft skills in veterinary students, allowing for self-learning and training in a controlled environment. Full article

Due to their frequent contact with animals, veterinarians may be at preferential risk of Coxiella burnetii exposure due to occupational contact with livestock. This study assesses the seroprevalence and risk factors associated with C. burnetii seropositivity in Portuguese veterinarians. A cross-sectional study compared IgG anti-C. burnetii in veterinarians’ sera to a demographically matched control group. Univariate and multivariate logistic regression analyses evaluated associations between the demographic, occupational, and biosecurity factors and seropositivity. Seroprevalence among veterinarians was 33.7%, significantly higher (p = 0.0023) than in the controls (17.39%). Univariate analysis identified higher seropositivity in the northern region (p = 0.03), though this association was not significant after adjustment (p = 0.07). Protective measures, including isolating aborting animals from the rest of the herd (adjusted OR [aOR]: 0.35, p = 0.03) and wearing gloves during sample collection (OR: 0.28, p = 0.009), were significantly associated with lower infection risk. Veterinarians face increased C. burnetii exposure, but specific biosecurity practices reduce risk. Strengthening preventive measures, including personal protective equipment (PPE) use and biosecurity training, is essential to mitigate occupational and public health risks. Further research should explore vaccination strategies and molecular epidemiology to improve risk reduction efforts. Full article

Natural and human-made disasters can severely impact communities and can result in high numbers of human injuries and deaths. Animals, both companion and livestock, are often injured as a result of these disasters and require veterinary care. Veterinarians are not only involved in providing care for these animals but also play important roles in planning and preparedness functions that occur before a disaster strikes. There are several examples of the use of multi-user virtual environments (MUVE) to provide human health care workers with valuable training centered on disaster response and disaster medicine. This communication provides a thorough review of a clinical rotation, as part of a professional veterinary curriculum, that uses a combination of classroom and experiential learning via an MUVE, Second Life^®. This rotation has provided more than 1800 senior veterinary students at a veterinary school in the United States with experiential learning opportunities focused on veterinary disaster preparedness, planning, and response training. The authors have prepared this communication to provide other institutions and educators with information on the practical implementation of Second Life^® in teaching and to offer recommendations based on our institutional experience.

Managing relinquished/stray dogs is a significant socio-economic and ethical challenge necessitating structured policies to ensure animal welfare and integration into society. Critical to successful rehoming is careful assessment of a dog’s temperament/behavior and appropriate matching of a dog to an owner. Shelter dogs’ involvement in canine-assisted interventions (CAIs) provides a potential avenue for rehoming through appropriate dog educational programs. CAIs consist of structured interactions between dog and clients targeted at specific groups with physical/psychological/emotional impairments in various settings. However, there is a lack of standardized protocols for assessing shelter dogs’ suitability for CAI, raising ethical concerns regarding selection/training practices. This study explores the ethical dimensions of rehoming shelter dogs for CAI, employing a philosophical framework considering the responsibilities of humans/veterinarians toward companion animals and how societal perceptions of human–animal relationships impact decision-making in this context. An ethical matrix is applied to evaluate the implications of rehoming decisions on canine and human interests. Our findings highlight the need for a balanced, responsible approach that respects the individuality of dogs while promoting their potential roles in human society. Ethical guidelines for the selection and training of shelter dogs for CAI could enhance their welfare, improve adoption rates, and reinforce the value of the human–animal bond. Full article

Cataracts are a prevalent cause of vision loss in dogs, and timely diagnosis is essential for effective treatment. This study aimed to develop and evaluate deep learning models to automatically classify canine cataracts from ocular ultrasound images. A dataset of 3155 ultrasound images (comprising 1329 No cataract, 614 Cortical, 1033 Mature, and 179 Hypermature cases) was used to train and validate four widely used deep learning models (AlexNet, EfficientNetB3, ResNet50, and DenseNet161). Data augmentation and normalization techniques were applied to address category imbalance. DenseNet161 demonstrated the best performance, achieving a test accuracy of 92.03% and an F1-score of 0.8744. The confusion matrix revealed that the model attained the highest accuracy for the No cataract category (99.0%), followed by Cortical (90.3%) and Mature (86.5%) cataracts, while Hypermature cataracts were classified with lower accuracy (78.6%). Receiver Operating Characteristic (ROC) curve analysis confirmed strong discriminative ability, with an area under the curve (AUC) of 0.99. Visual interpretation using Gradient-weighted Class Activation Mapping indicated that the model effectively focused on clinically relevant regions. This deep learning-based classification framework shows significant potential for assisting veterinarians in diagnosing cataracts, thereby improving clinical decision-making in veterinary ophthalmology.

Feline healthcare phobia is a major challenge in veterinary practice, limiting medical care and increasing stress for cats, owners, and veterinarians. Traditional desensitization–counter-conditioning (DS-CC) protocols aim to reduce fear responses, but their success is limited in sensitized cats. This study evaluates whether gabapentin can improve the efficiency of DS-CC training in healthcare phobia in cats. Forty-two sensitized cats participated in a claw-trimming learning protocol. Using a double-blind, placebo-controlled crossover trial, the cats followed 10 training sessions: the first 5 under one product and the last 5 under the other one. Their progression through the learning steps was monitored. The results indicate that gabapentin significantly accelerated the cats’ ability to complete DS-CC steps, suggesting a positive effect on the learning process. While some side effects, such as mild sedation and ataxia, were observed in 42% of the cats, they were transient and did not hinder participation. These findings suggest that gabapentin should be added when engaging patients in DS-CC protocols in order to lower the time needed to achieve therapy, which will improve the overall welfare of our patients. Further studies are needed to confirm these results in other types of therapies and in a clinical setting. Full article

A pilot study was conducted with 5th–8th semester students comparing a 3D-printed simulator and a virtual 3D simulation. This study’s aim was the comparison of these two resources in three different settings. Assessment of the resources’ suitability as teaching devices for performing a central plastrotomy in chelonians took place. One group used the simulator, while the other group used the simulation to practice this method in a preparation course. Afterwards, the practical skills of 28 students were validated in an objective structured clinical examination (OSCE). The students evaluated their respective resources (simulator and simulation). Additionally, 10 practicing veterinarians evaluated the simulator and rated its fidelity as suitable for practicing a plastrotomy. Furthermore, the self-efficacy of the two student groups was compared with each other. An increase in subjective self-assessment of skills in both groups was identified. Students trained on the simulator achieved better results in the OSCE and self-assessment of skills than those trained with the simulation. However, the differences between the groups regarding these aspects were mostly not significant. This study indicates that a 3D-printed chelonian simulator serves as an appropriate teaching device for veterinary students and is a useful addition to established teaching methods, like using cadavers.

Data from post-mortem inspections conducted using official controls on the meat production of slaughtered pigs are generally considered valuable for identifying herd health issues and ensuring meat safety. However, several studies highlighted that a multi-stage assessment of lung changes would provide more useful information on animal health than the implemented binary (yes/no) recording. For this purpose, a new scheme was developed and subsequently used by trained official veterinarians at four slaughterhouses in Austria. Implementation of the multi-stage assessment was carried out in parallel with the conventional assessment, and data collected from both schemes were analyzed and compared to evaluate effectiveness. The analysis of the data (n = 20,345) showed that the most common alteration was low-grade (28.4%), followed by moderate-grade (11.3%,) and then high-grade pneumonia (5.2%). In the case of pleurisy, 88.9% of the carcasses showed no alterations of the pleura, and 11.1% had pathological changes (low-grade pleurisy = 4.7%, moderate-grade pleurisy = 2.7%, high-grade pleurisy = 3.7%). Analysis of the results showed a strong heterogeneity of the frequency of alterations between the batches reflecting various underlying animal health issues. Among the influencing factors, the origin of the pigs had the greatest influence. The project demonstrated that the new evaluation can be carried out easily with no extra time effort once staff are trained and the technological platform for reporting is adapted. The more detailed information ensures more useful feedback is provided to the farmers and supervising veterinarians, thereby ensuing animal welfare and contributing to sustainable, improved animal husbandry.

Aquatic training has been integrated into equine rehabilitation and training programs for several decades. While the cardiovascular effects of this training have been explored in previous studies, limited research exists on the locomotor patterns exhibited during the swimming cycle. This study aimed to analyze three distinct swimming strategies, identified by veterinarians, based on the propulsion phases of each limb: (S1) two-beat cycle with lateral overlap, (S2) two-beat cycle with diagonal overlap, and (S3) four-beat cycle. 125 underwater videos from eleven horses accustomed to swimming were examined to quantify the differences in locomotor patterns between these strategies. Initially, a classifier was developed to categorize 125 video segments into four groups (CatA to CatD). The results demonstrated that these categories correspond to specific swimming strategies, with CatA aligning with S1, CatB with S2, and CatC and CatD representing variations of S3. This classification highlights that two key parameters, lateral and diagonal ratios, are indeed effective in distinguishing between the different swimming strategies. Additionally, coordination patterns were analyzed in relation to these swimming strategies. One of the primary findings is the variability in swimming strategies both within and between individual horses. While five horses consistently maintained the same strategy throughout their swimming sessions, six others exhibited variations in their strategy between laps. This suggests that factors such as swimming direction, pauses between laps, and fatigue may influence the selection of swimming strategy. This study offers new insights into the locomotor patterns of horses during aquatic training and has implications for enhancing the design of rehabilitation protocols. Full article

This case study aims to problematise concepts of equine and human co-relational agency in the context of ‘mis-re-presentations’ in the Australian media of harms experienced by the Anglo Arab stallion, Cambridge, following his development of laminitis and his consequent confinement at a leading national Equestrian centre. Autoethnographic narrative is used to retrospectively and selectively narrate the evolving relationship between Cambridge and his owners, farrier, and treating veterinarians within the dominant housing and veterinary practices and welfare paradigms in equestrian culture of 1990’s Australia. Structured author/owner autoethnographic vignettes are framed by newspaper and internet reportage to highlight a productive tension between the public mediation of the case, and what it means to be fully embodied in relationship with an equine companion agent within a particular, racialised, gendered, and biopoliticised location. Adopting a phenomenologically informed intersectional feminist ethics of care perspective, a counternarrative to the gendered, racialised and essentialising rights-based judgements about Cambridge’s illness and eventual death that dominated the popular media is provided. Crucially, the autoethnographic vignettes are chosen to capture the corporeal reciprocity and rapport of forces that produced a co-created agentivity that characterised the horse’s birth, training, and treatment. The embodied interspecies knowledge that informs the training and care of equines (and all animal species) is always historically situated within permeable, dynamic worlds of self and other that are fluid, contextual, and always in relation. It is suggested that the case of Cambridge illustrates how competing stakeholder investments in animal welfare can play out in the public mediation of particular cases in ways that exclude their historical and interspecies situatedness and serve to reinforce dominant ideologies governing human and animal relationships.

The end-of-life (i.e., on-farm euthanasia and culling, including fitness for transport to slaughter) of a dairy cow or calf is preceded by a series of decisions often influenced by many complex factors. The aim of this study was to utilize the opinions of experts with roles in the dairy supply chain to identify factors that influence end-of-life decision-making for dairy cattle. Twenty experts serving in supporting roles in the dairy supply chain participated in a survey containing 17 open-ended questions. Of the participants, 55% (n = 11) identified as veterinarians and the remaining 45% (n = 9) participated in other segments of the dairy supply chain. Twelve themes were identified in the qualitative analysis of survey responses. The themes included: Training and Resources, Cattle Health Management, Decision-Making Criteria, Company Culture, Personal Beliefs, Human Well-Being, Animal Welfare, Economics, Guidelines and Inspections, Consumer Perceptions, Supply Chain Considerations, and Communication. Experts indicated that training programs should address euthanasia or fitness-for-transport criteria, the knowledge of common health conditions, and information about what happens to cattle after leaving the dairy. Additional influencing factors included personal beliefs, economics, company culture, and supply chain considerations. Full article

Lumpy skin disease (LSD), caused by the LSD virus (LSDV), a dsDNA virus of the genus Capripoxvirus, represents a significant cross-border infectious threat, particularly impacting cattle and water buffaloes through transmission by blood-feeding insects. Traditionally endemic to Southern Africa, LSD has rapidly spread over the past decade through the Middle East to Eastern Europe and China, reaching Korea in October 2023. This outbreak prompted a nationwide vaccination campaign, addressing both the disease’s severe economic impact and its status as a notifiable disease under the World Organisation for Animal Health. This study assesses the seropositivity of the LSD vaccine in cattle across four Korean provinces 2–3 months post-vaccination, aiming to inform improvements in biosecurity and vaccination strategies. Overall, 30.59% of the cattle tested (1196 out of 3910) exhibited positive antibody responses, comparable to international post-vaccination findings. Analysis further revealed differences in the antibody positivity between farm types and management practices. Specifically, farms where vaccines were administered by veterinarians showed no significant difference in antibody positivity between Korean native cattle and dairy cattle, regardless of the presence of restraint facilities. However, on farms where vaccinations were conducted by the owners, dairy cattle demonstrated a higher seropositivity (43.30 ± 33.39%) compared to Korean native cattle (21.97 ± 20.79%) in the absence of restraint facilities. Further comparisons underscored the impact of restraint facilities on vaccination efficacy, with dairy farms generally achieving higher antibody positivity (29.43 ± 30.61%) than farms with Korean native cattle (23.02 ± 23.33%) (p < 0.05), suggesting that consistent vaccine delivery methods enhance immunogenic responses. Contrarily, no significant difference was noted in antibody positivity between large- and small-scale farms, indicating that farm size did not notably impact the effectiveness of the vaccinator. These findings emphasize that while current vaccines are sufficiently inducing immunity, enhancing vaccination strategies, particularly through trained personnel and improved restraint facilities, is crucial. This study’s insights into the impact of vaccination and farm management practices provide valuable guidance for refining LSD control measures in Korea and potentially other affected regions.
