Special Issue Information

Dear Colleagues,

Invasive and superficial fungal infections result in a noteworthy global rate of morbidity and mortality. It is recognized that the pathogenicity of fungal species is closely related to the general host immunity state. Indeed, this occurs very commonly as a consequence of other health problems, such as cancer, HIV, denture wearing, tobacco smoking, chemo, and corticosteroid therapies. The quick identification and detection of the fungal species involved in infections is crucial to apply an effective treatment. Additionally, in recent decades, antifungal drug resistance has been growing fast. Taking into consideration the increasing number of fungal species and strains with elevated antifungal drug resistance, it is quite important to search for effective alternative therapies to the current antifungal agents (e.g., natural and synthetic compounds, photodynamic therapy).

This SI intents to present new data on fungal infections, fungal biofilms, novel treatments, and innovative and quick methods (e.g., microfluidic devices, molecular techniques) to identify fungal pathogens. Original articles, case studies, and reviews are welcome.

Aspergillosis is a fungal disease caused by the inhalation of Aspergillus spores, with Aspergillus fumigatus being the primary causative agent. This thermotolerant fungus affects both immunocompetent and immunocompromised individuals, posing a significant public health concern. In recent years, the detection of A. fumigatus in food products and production environments has raised questions about its potential role as an additional route of exposure. Furthermore, the emergence of azole-resistant strains in agricultural settings highlights the need to better understand its transmission dynamics and implications for food safety. This review explores the occurrence of A. fumigatus in crops and food products, its possible routes of contamination, and the potential link between environmental exposure to azole fungicides and resistance development. Additionally, it identifies knowledge gaps and proposes future research directions to improve risk assessment and mitigation strategies within the food production chain. Full article

Histoplasmosis has traditionally been described as having discrete geographic areas of endemicity. Over the last few decades, it has become more and more clear that these areas are not accurate depictions of where histoplasmosis can occur. Our understanding of where histoplasmosis occurs has improved in recent years due to improving access to diagnostic testing and increased reporting as well as larger at-risk populations (HIV and non-HIV immune suppression) resulting in more cases. Although areas of relatively higher risk and case numbers certainly still exist, histoplasmosis has been observed in much of the world at this point. Our knowledge of the geographic distribution of histoplasmosis, though improving, remains incomplete. While diagnostic testing has traditionally been confined to visualization and/or culture in much of the world, antigen testing has emerged as an excellent tool. Unfortunately access to antigen testing has been inadequate for much of the world, but this has started to change in recent years and will likely change more dramatically in the near future, assuming ongoing positive developments in the area of lateral flow tests for antigen testing. In this review, we describe the current understanding of the geographic distribution of histoplasmosis, the current landscape of diagnostic testing, and the evolution of both areas with an eye towards the future.

We performed a thorough search of the literature published through December 2024 with no date exclusions on invasive fungal infection (IFI)-induced hemophagocytic lymphohistiocytosis (HLH) in non-human immunodeficiency virus (HIV) patients. The frequency of IFI-induced HLH reported across 16 articles was 9%. Of the 116 identified cases with available clinical information, 53% occurred in immunocompromised patients. IFIs were usually disseminated (76%), with Histoplasma capsulatum being the most common pathogen (51%). IFI and HLH were diagnosed simultaneously in most cases (78%). The 30-day survival rate was 64%. Reported cases had significant heterogeneity in patient characteristics, management strategies, and outcomes. Full article

Pneumocystis jirovecii is an opportunistic fungus that causes severe pneumonia in immunosuppressed individuals. While Pneumocystis colonization, a subclinical form of infection, has been studied in different populations, its implications during pregnancy remain poorly understood. Given the immune modulation of pregnancy, maternal colonization or infection may contribute to vertical transmission and neonatal respiratory complications. This scoping review aims to map the existing evidence on Pneumocystis colonization/infection during pregnancy, identifying knowledge gaps, prevalence, risk factors, and potential neonatal outcomes. A systematic literature search was conducted in three databases following PRISMA-ScR guidelines. A total of 26 studies were included, covering Pneumocystis pneumonia cases (n = 19) and Pneumocystis colonization (n = 7). The review found that most Pneumocystis pneumonia cases in pregnant women were associated with HIV before antiretroviral therapy. More recent cases were related to hematologic malignancies. Pneumocystis colonization rates varied widely (5.4–46.5%). Evidence of vertical transmission was observed, but neonatal impact remains underexplored. This review highlights the need for HIV screening in pregnant women and the need to include Pneumocystis in the diagnosis of pregnant women with pneumonia. Increased awareness and research on Pneumocystis in pregnancy are necessary to improve maternal and neonatal outcomes. Future studies should focus on vertical transmission and neonatal respiratory health. Full article
