Yet, both the dynamic of Malassezia skin colonization and the associated fungal and bacterial skin microbiome remain unknown in HIV+ patients. This study aimed to compare Malassezia yeast community structure and associated microbiome on the healthy skin of HIV+ patients and healthy controls. A total of 23 HIV+ patients and 10 healthy controls were included and followed-up for a maximum of 5 visits over 10 to 17 months. At each visit, chest, face, nasolabial fold, and scalp skin samples were subjected to both culture and MALDI-TOF MS identification, and ITS/16S metabarcoding. The participants were categorized according to their Malassezia colony forming unit (CFU) abundance. Malassezia were cultured from each participant at each visit. HIV+ patients were highly colonized on all visits with CFU >100. M. sympodialis and M. globosa were the most dominant species. M. furfur and M. dermatis were more prevalent in HIV+ than in healthy participants. M. sympodialis prevalence was stable at each sampling sites over time. M. furfur prevalence was stable and more abundant over time on HIV+ patients' chest. The metabarcoding analysis suggested a higher fungal and bacterial diversity and an increased abundance of Cladosporium halotolerans and Streptococcus in HIV+ patients than in controls. Overall, HIV+ patients display a high skin colonization by Malassezia yeasts and a dysbiosis of both fungal and bacterial communities.</p>","PeriodicalId":18586,"journal":{"name":"Medical mycology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fungal infections, molecules involved in adhesion to host tissues or catheters are one of the pathogenic factors. A single strain of T. asahii produces various colony morphologies, including highly adhesive colony types, but the molecules involved in the adhesiveness have not been identified. This study compared proteins in cell-surface extracts from weakly and highly adherent colony types and identified a protein abundantly expressed in highly adherent cells, which was named T. asahii R-type lectin domain-containing protein (TAL). TAL was a predicted 48 kDa protein with a carbohydrate-binding region, but a band was detected at ∼250 kDa in sodium dodecyl sulfate-polyacrylamide gel electrophoresis, suggesting that it was highly glycosylated. When TAL was overexpressed in mammalian cells and deglycosylated, the protein size decreased, confirming that it was glycosylated. In weakly adherent colony-type cells, the bands detected by anti-TAL antiserum were barely noted. The absence of bands indicates that the protein expression was low and does not suggest that the degree of glycosylation was different.

Diagnosis typically relies on rapid Cryptococcus antigen (CrAg) testing, and antigen titer quantification helps in early detection and assessing disease severity. However, conventional titer methods are often more expensive than qualitative antigen detection. This study assessed the diagnostic performance of a semi-quantitative Lateral Flow Assay (CrAgSQ LFA, IMMY™) for CrAg detection in serum and cerebrospinal fluid (CSF) collected between 2014-2022. The CrAgSQ LFA was compared to the standard CrAg LFA (IMMY™) and Clarus Cryptococcal Ag enzyme immunoassay (EIA-CrAg, IMMY™). The CrAgSQ LFA demonstrated 100% sensitivity and specificity in both serum and CSF, with perfect agreement (kappa 1.00) with the CrAg LFA. Comparing the CrAgSQ LFA with the titer measurement results obtained using CrAg LFA, in category 1+, titers ranged from 1:2-1:20; in 2+, from 1:5-1:40; in 3+, from 1:20-1:2560; and in category 4+, from 1:320-1:2560.Titer results for the CrAgSQ LFA aligned well with CrAg LFA, and operator agreement was strong, with weighted kappa values of 0.926 and 0.966.
