Through flow cytometry, we observed that long-term dexamethasone treatment reproducibly reduced the frequency and cell numbers of CD4 T cells in the peripheral blood and bronchoalveolar lavage (BAL) in both Japanese (Macaca fuscata) and rhesus macaques (Macaca mulatta), reflective of a state of chronic immunosuppression. This was accompanied by a reduction in the frequency and cell number of CD20 + B cells and the absence of antibody responses against the protective Pneumocystis antigen KEX1 in the peripheral blood. Pneumocystis-specific polymerase chain reaction and histologic evidence of Pneumocystis infection in serial BAL samples demonstrated that dexamethasone induced immunosuppression rendered both Japanese and rhesus macaques susceptible to persistent Pneumocystis colonization and subsequent infection.

To develop and validate the LODDY Test-a novel, cost-effective, pH-indicator-based culture medium for rapid, accurate identification of L. elongisporus, particularly in resource-limited settings. The LODDY Test integrates four differential carbohydrates (sucrose, maltose, lactose, and arabinose) with bromocresol purple. We tested 41 L. elongisporus isolates (1 reference, 40 internal transcribed spacer (ITS) region -confirmed environmental strains) and 40 comparator yeasts (C. parapsilosis sensu stricto, C. albicans, C. tropicalis, and Nakaseomyces glabratus) from urban/peri-urban Thai sites. Species identity was confirmed by ITS sequencing. LODDY results were benchmarked against the Analytical Profile Index 20C Auxanographic assimilation test (API 20C AUX), CHROMagar™ chromogenic medium, and Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS), and ITS-DNA sequencing. The LODDY Test achieved 100% sensitivity and specificity, distinctly identifying L. elongisporus (no color change) from yellow-producing Candida spp. and purple N. glabratus.

In this study, we applied a nested polymerase chain reaction targeting TUB1 to amplify fungal sequences from two new cases of PCMC in Brazil: a Lahille's bottlenose dolphin (Tursiops truncatus gephyreus) and a common bottlenose dolphin (T. truncatus truncatus).

Our findings demonstrate that the nested PCR assay, originally developed for cultivable Paracoccidioides species, is also effective in amplifying TUB1 from P. ceti.

An audit was conducted of all fluconazole prescriptions from January 2024 to March 2024 at two Sydney hospitals. Trained pharmacy students, under the supervision of antimicrobial stewardship pharmacists and physicians, completed the audit using the Antifungal National Antimicrobial Prescribing Survey audit tool. Prescriptions were assessed for their compliance to guidelines and appropriateness. Data on pharmacy students' educational experience was collected by a 5-point Likert scale survey. A total of 145 fluconazole prescriptions were audited: 34 for empiric therapy, 56 for directed therapy, and 56 for prophylaxis. A total of 91 (62.8%) prescriptions were assessed as appropriate, 46 (31.7%) were inappropriate, and 8 (5.5%) were not assessable.

Ten clinical isolates were molecularly identified and assessed for virulence by determining enzymatic activity (proteases, lipases, catalase), biofilm formation, adhesion to extracellular matrix proteins, antifungal susceptibility, and cell wall composition. Host interaction was evaluated through cytokine profiling in human peripheral blood mononuclear cells, and virulence was assessed using the Galleria mellonella invertebrate infection model. All isolates were confirmed as S. schenckii. Compared to a reference strain, a subset of isolates (740, 742, 183, and 1798) displayed reduced adhesion, extracellular enzymatic activity, and catalase production, as well as altered mannose and rhamnose cell wall content. These isolates induced significantly lower TNFα and higher IL-10 levels in PBMCs and were markedly less virulent in G. mellonella, exhibiting lower mortality, cytotoxicity, and immune activation. All isolates were biofilm producers, and some showed reduced susceptibility to itraconazole or fluconazole. This study reveals phenotypic diversity among S. schenckii clinical isolates in a Mexican hyperendemic region and identifies a subgroup with reduced virulence and immune stimulation capacity.

This study aimed to investigate the influence of Malassezia restricta, a predominant fungal species on human skin, on the virulence of Staphylococcus aureus, a prominent skin bacterium associated with atopic dermatitis. Our findings revealed that M. restricta effectively interferes with the invasion of S. aureus into human keratinocytes, suggesting a potential mechanism for influencing bacterial infection by the fungus. Additionally, we observed that M. restricta exhibits fibronectin binding capabilities, a key mediator in the S. aureus invasion of keratinocytes. Physicochemical analysis indicated the involvement of a heat-unstable component, likely a M. restricta cell surface protein, which necessitates physical contact between the fungus and keratinocytes for fibronectin binding.

Precise identification of T. indotineae is essential for timely and effective therapy, and for curbing the spread of antifungal resistance. However, current routine diagnostic methods are limited to reliably distinguish T. indotineae from other closely related dermatophytes. This study aimed to develop and evaluate three simple, cost-effective molecular methods for the accurate differentiation of T. indotineae. In silico analyses were performed to identify specific restriction enzyme cut sites within the internal transcribed spacer (ITS) region and the topoisomerase II gene of T. indotineae. A total of 430 dermatophyte isolates, including 267 previously identified by ITS sequencing and 163 clinical isolates of unknown identity, were subjected to PCR amplification of ITS and topoisomerase II followed by restriction fragment length polymorphism (PCR-RFLP) analysis using EarI (Eam11041) and BsuRI (HaeIII), respectively. Additionally, a previously described T. indotineae-specific PCR assay was evaluated. The enzyme EarI digested the ITS region of T. indotineae, producing a distinct PCR-RFLP pattern; likewise, BsuRI digested the topoisomerase II gene, enabling accurate differentiation of T. indotineae. The isolates previously identified by ITS sequencing were correctly classified by both methods, achieving high sensitivity and specificity. The T. indotineae-specific PCR assay demonstrated high sensitivity, although faint cross-reactivity was observed with T. tonsurans isolates. The ITS-PCR-RFLP and topoisomerase II-PCR-RFLP methods demonstrated high accuracy, affordability, and speed for the reliable identification of T. indotineae, making them suitable for routine use in clinical laboratories, especially in resource-limited settings.
