“…Even though it is more common in superficial mycoses, the species T. inkin , isolated in the present case, has already been related to cases of meningitis [17], esophagitis [18], endocarditis [19], and skin abscesses [20], among other forms of invasive infections. In addition, it has also been associated with a case of onychomycosis [21], and was isolated in water used in a hemodialysis center in Brazil [22].…”

We report a case of white piedra of the scalp caused by Trichosporon inkin in a 38-year-old woman living in southern Brazil. Trichoscopic examination revealed whitish nodules involving the hair shafts. Blastoconidia clustered around the hair shaft were visualized by light microscopy with 10% KOH. The isolate was molecularly identified, and its antifungal susceptibility profile was defined following the M27-A3 protocol of the Clinical and Laboratory Standards Institute (CLSI), with itraconazole being the most effective antifungal agent, followed by ketoconazole. For treatment, topical medications were used, consisting of 1% itraconazole solution and 2% ketoconazole shampoo for 30 days. The literature on cases of white piedra of the scalp caused by T. inkin, in addition to the in vitro antifungal susceptibility profile of this species, was reviewed.

“…Trichosporon sp are yeast like fungi and can cause invasive disease [64]. Trichosporon sp has emerged as an important nosocomial pathogen causing fungemia with a high mortality rate in immunocompromised patients [65]. T. inkin causes skin infections, onychomycosis, pneumonia, endocarditis, peritonitis, lung abscess, and other invasive infections [65, 66].…”

Nosocomial infections, in lay term known as hospital acquired infections, are caused mainly by airborne pathogens found in healthcare facilities and their surroundings. The aim of this study was to quantify and identify bacteria and fungi in a hospital, which is an understudied area of air quality in Sri Lanka. Air samples were collected in agar medium and petri plates containing sterile filter papers. The number of culturable and total airborne microorganisms was estimated by manual counting and fluorescent microscopy, respectively. The morphologically distant bacteria and fungi were identified by DNA sequencing. The statistical analysis revealed significant variances between studied sites (p < 0.05) where Outpatients Department and Respiratory Unit showed higher levels of airborne microbial load. Culturable microbial count was higher at noon (hospital visiting hours) compared to other sampling periods (after hospital visiting hours) within the hospital. Total count of airborne microbes was found to be the highest during the afternoon. The most sensitive zones such as Operating Theatre and Intensive Care Unit showed considerably higher counts of airborne microbes. Identification by molecular means revealed the presence of human pathogens in the hospital air including Bacillus sp, Micrococcus sp, Pseudomonas sp, Staphylococcu ssp, Exiguobacterium sp, Enterobacter sp, Escherichia sp, Sphingomonas sp, Massilia sp, Kocuria sp, Fusarium sp, and Aspergillus sp. In conclusion, the results from this study indicate that the hospital air was generally contaminated. Therefore, the implementation of proactive policies and strategies are needed to monitor hospital air quality in sensitive zones as well as other areas of the hospitals.

“…After that, some mycologists recovered other species of Trichosporon also as common agents of onychomycosis from different parts of the world and their frequency ranged from 0.87% to 8.0% . Among the various Trichosporon species, T. cutaneum was recovered as nail pathogen from Nigeria, Denmark and Leipzig/Alemanha, whereas T. mucoides , T. capitatum, T. inkin , T. ovoides and T. dohaense were recovered as etiological agents of onychomycosis from different parts of the globe by Mugge et al, Souza et al, Taj‐ Aldeen et al, Sageerabanoo et al, Ortega‐Sprigall et al, Capoor et al, de Magalhaes et al and Rizzitelli et al …”

“…They also exist as commensals in the human gastrointestinal and respiratory tracts . However, they are opportunists and are recognized as emerging fungal pathogens in immune‐compromised hosts, where they can cause fungaemia with a high mortality rate, systemic illness, solid tumours, haematological malignancies and generally trichosporonosis . Trichosporon species are also causative agents of superficial infections like white piedra and onychomycosis …”

Dermatophytes are considered as the main pathogens responsible for onychomycosis, but recently successive isolations of yeast-like fungi from the infected nails has led to consider these also as primary agents of nail infections. Trichosporon species which are non-candidal, basidiomycetous, yeast-like, anamorphic fungi are commonly isolated from soil but they are also emerging as important etiological agents of onychomycosis. Three species of Trichosporon viz., T. asahii, T. asteroides and T. faecale were isolated from the infected nails of three female members of a family from district Doda of Jammu and Kashmir State. Among the isolated species of Trichosporon, T. asahii was recovered from the nail samples of all the three members, thus confirming its recognition as a main pathogenic species of onychomycosis. So far, there is no report of T. asteroides and T. faecale causing onychomycosis and hence they constitute new additions to the list of onychomycotic fungi. Some of the predisposing factors like low socio-economic condition, poor hygiene, frequent exposure of finger nails to water and dirt, climatic conditions and nail trauma were observed to be the main causes of nail infection in these patients. However, a link between the pathogenic genus and the genetic makeup of the patients is also probable.
