At the initial examination, a 3-cm brownish plaque associated with mild pain was observed on the dorsum of the right hand. Histopathological examination revealed a mass of hyphae in the subcutaneous tissue that was positive for periodic acid-Schiff and Grocott's stains. Fungal culture of the skin tissue yielded black-brown, downy colonies. Based on nucleotide sequencing of the internal transcribed spacer region and the β-tubulin gene, the organism was identified as Phaeoacremonium alvesii. After oral administration of terbinafine (TBF) at 125 mg/day was initiated, the lesions gradually improved. The strain exhibited slightly reduced sensitivity to TBF (minimum inhibitory concentration: 1 μg/mL). More than six months of oral therapy was required to achieve remission of the skin lesions. P. alvesii is a recently classified species, redefined in 2005 based on β-tubulin gene analysis, with only a few reported cases of human infection.","PeriodicalId":520314,"journal":{"name":"Medical mycology journal","volume":"67 1","pages":"27-31"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147329126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To clarify their clinical significance, we analyzed the fungal species, their sources and associated diseases of 650 basidiomycetous strains preserved at the Medical Mycology Research Center, Chiba University, from 2010 to 2024. Schizophyllum commune was the most frequently isolated species (60%), followed by Trametes spp. (9.5%), Irpex spp. (5.2%), and Bjerkandera adusta (4.3%). Most isolates originated from respiratory specimens and were associated with ABPM, pneumomycosis, or sinusitis. These fungi often cannot be identified in culture because of their limited morphological characteristics. Therefore, we developed a multiplex polymerase chain reaction (PCR) assay targeting the internal transcribed spacer region for the rapid discrimination of S. commune, B. adusta, Irpex spp., and Trametes spp. Species- and genus-specific forward and reverse primers yielded distinct amplicon sizes for each target. The assay demonstrated high specificity and showed no cross-reactivity with non-target fungi; the results were concordant with those of rDNA sequencing. Multiplex PCR provides a rapid, cost-effective tool for identifying clinically important basidiomycetes, facilitating the timely diagnosis and management of fungal respiratory diseases.","PeriodicalId":520314,"journal":{"name":"Medical mycology journal","volume":"67 1","pages":"19-25"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147329135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among fungi, dermatophytes are well-established zoonotic pathogens. In contrast, many pathogenic molds are environmental saprophytes, with infections typically resulting from the direct uptake of fungal propagules-such as airborne spores-from soil, decaying organic matter, or other non-living reservoirs. Rather than being transmitted between animals and humans, these infections originate from environmental sources. In 1958, Terskikh introduced the term \"sapronosis\" (or \"saprozoonosis\") to describe such infections acquired from the environment rather than from other living hosts. In 2003, Hubálek expanded on this concept, providing a comprehensive list of major sapronoses and their causative agents, including Aspergillus fumigatus, the primary cause of aspergillosis. Aspergillosis is a fungal disease caused by species of the genus Aspergillus, typically acquired through inhalation of airborne spores from soil and other external environments. Although the environmental transmission of Aspergillus spp. has long been recognized, recent changes in human living environments, evolving animal husbandry practices, and global ecological shifts-including climate change and the human-mediated dispersal of pathogenic organisms-highlight the need to re-evaluate these fungi as sapronotic agents. In this review, we revisit the concept of sapronosis using aspergillosis as a representative example, drawing on investigations conducted in collaboration with colleagues involving penguins housed in zoos and aquariums and the characteristics of their captive environments. Through these studies, we aim to explore the implications of environmental fungal exposure for both human and animal health.","PeriodicalId":520314,"journal":{"name":"Medical mycology journal","volume":"67 1","pages":"67-70"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147329130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
