An investigation of members of the soil keratinophilic fungi community in China resulted in the identification of one new monotypic genus, , and 10 new species, 2 of which are affiliated with , 1 with the new genus , 4 with , and 3 with . These novel taxa form an independent lineage distinct from other species, based on morphological and multilocus phylogenetic analyses. Descriptions, illustrations, and notes are provided for each taxon. These new taxa of the soil keratinophilic fungi add to the increasing number of fungi known from China, and it is now evident that numerous novel taxa are waiting to be described. Keratinophilic fungi are a group that can degrade and utilize keratin-rich material. It is also because of this ability that many taxa can cause infections in animals or humans but remain poorly studied. In this study, we reported a novel genus and 10 novel species, 7 novel species belonging to the order and 3 to the genus , based on multilocus phylogenetic analyses combined with morphological characteristics. Our study significantly updates the taxonomy of and and enhances our understanding of this group of the keratin-degrading fungal community. The findings also encourage future studies on the artificially constructed keratin-degrading microbial consortia.

Background And Purposes: The fungi known as dermatophytes are a group of keratinophilic agents responsible for superficial infections in humans and animals. Recognition of the species distribution and epidemiology of dermatophytosis may be helpful in the prevention and improve prophylactic measures. The present molecular epidemiology study sought to investigate the incidence of etiological agents causing dermatophytosis.

Keratinophilic fungi, or dermatophytes, are recognized as the predominant fungal agents responsible for superficial skin diseases globally. The identification of species of dermatophytes is crucial for both therapeutic and epidemiological considerations. The primary objective of the present study was to investigate the epidemiology of dermatophytosis among patients who sought medical attention at the medical mycology laboratory in Golestan province.

The purpose of this research was to identify the role of keratin proteins in causing inherited as well as pathogenic alopecia, pinpoint deleterious SNPs, and predict structural changes affecting protein-protein interactions in hair disorders. To elucidate the role of keratin proteins and genetic mutations in alopecia by analyzing protein structures through bioinformatics and identifying a mutation in the LPAR6 gene. It sought to identify the microorganisms linked to alopecia and conducted a comprehensive bioinformatics analysis of proteins with unknown experimental structures and molecular simulation analysis.

Screening for new bioactive microbial metabolites, we found a novel okaramine derivative, for which we propose the trivial name lemmokaramine, as well as two already known okaramine congeners - okaramine H and okaramine J - responsible for antimicrobial activity of the recently described microscopic filamentous fungus, Keratinophyton lemmensii BiMM-F76 (= CCF 6359). In addition, two novel substances, a new cyclohexyl denominated lemmensihexol and a new tetrahydroxypyrane denominated lemmensipyrane, were purified and characterized. The compounds were isolated from the culture extract of the fungus grown on modified yeast extract sucrose medium by means of flash chromatography followed by preparative HPLC.

Dermatophytes are widely distributed in the environment, with an estimated prevalence of 20-25% of the the global population yearly. These fungi are keratinophilic and keratinolytic and cause the infection of keratin-rich structures such as skin, hair, and nails. The pattern of this infectious disease covers a wide spectrum from exposed individuals without symptoms to those with acutely inflammatory or non-inflammatory, chronic to invasive, and even life-threatening symptoms.
