“…T. jirovecii genotype 1 has been isolated from the human body(9), but its pathogenicity was unknown. Thus far, there have been few reports on T. jirovecii: Malgorzata et al reported one case of mixed respiratory infection in a dog caused by T. jirovecii and Rhodotorula (31, 32), and Nardoni reported one case of back infection in a tortoise caused by T. jirovecii (7). In this study, four strains of T. laibachii (JYZ3252, JYZ921, JYZ321, and JYZ912) and one strain of T. moniliiforme (JYZ372) were identified as having new genotypes.…”

Trichosporon is the dominant genus of epidermal fungi in giant pandas and causes local and deep infections. To provide the information needed for the diagnosis and treatment of trichosporosis in giant pandas, the sequence of ITS, D1/D2, and IGS1 loci in 29 isolates of Trichosporon spp. which isolated from the body surface of giant pandas were combination to investigate interspecies identification and genotype. Morphological development was examined via slide culture. Additionally, mice were infected by skin inunction, intraperitoneal injection, and subcutaneous injection for evaluation of pathogenicity. The twenty-nine isolates of Trichosporon spp. were identified as belonging to 11 species, and Trichosporon jirovecii and T. asteroides were the commonest species. Four strains of T. laibachii and one strain of T. moniliiforme were found to be of novel genotypes, and T. jirovecii was identified to be genotype 1. T. asteroides had the same genotype which involved in disseminated trichosporosis. The morphological development processes of the Trichosporon spp. were clearly different, especially in the processes of single-spore development. Pathogenicity studies showed that 7 species damaged the liver and skin in mice, and their pathogenicity was stronger than other 4 species. T. asteroides had the strongest pathogenicity and might provoke invasive infection. The pathological characteristics of liver and skin infections caused by different Trichosporon spp. were similar. So it is necessary to identify the species of Trichosporon on the surface of giant panda. Combination of ITS, D1/D2, and IGS1 loci analysis, and morphological development process can effectively identify the genotype of Trichosporon spp.

“…Trichosporon signi cance lies as a yeast pathogen and reports as causative agents of fungal infections. They can cause super cial, deep-seated and life-threatening infections in immunocompromised patients, but rarely within animals [42], [43]. Multiple species of Trichosporon are associated with clinical diseases, such as nasal granuloma formation and systemic fungal infection which has been reported in cats and other animals [44], [45].…”

The gut mycobiome exhibits major influence on the feline gastrointestinal health and disease but received less attention due to low microbial abundance. This study aims to characterise the fungal community and compare the microbial diversity between indoor and outdoor cats that devoured to different diets. The fecal samples used in this study were obtained from five indoor and five outdoor cats. Genomic DNA was extracted and sequenced by targeting the full-length internal transcribed spacer 1 (ITS1) region using Flongle flow cell on MinION™ sequencing platform. We discovered that the Ascomycota phylum and Peniophorella genus were numerous in indoor cats, whereas the Basidiomycota phyla and Pichia genus were abundant in outdoor cats. The genus Peniophorella formed the core mycobiome in both indoor and outdoor feline populations. Furthermore, alpha diversity (p-value = 0.0207) revealed that the fungal composition of outdoor cats had greater variety within the sample than that of indoor cats. The mycobiome composition differed significantly between the two groups, as demonstrated by beta diversity (p-value = 0.009) using the Bray-Curtis index distance technique. Overall, indoor cats have greater amounts of Peniophorella, whereas outdoor cats have higher Trichosporon and unclassified Sordariaceae. The study also suggests that keeping a cat indoors or left as a stray will affect their respective gut mycobiome.
