Abstract
Epidermophyton floccosum is one of the most common agents of human superficial fungal infections, compared with genus Trichophyton and Microsporum, it possesses uniqueness in ecology traits and rarely causing hair infections. E. floccosum is so far the only representative species of genera Epidermophyton, and it is known as anthropophilic dermatophytes. To further reveal the genome sequences and clues of virulence factors, thus in this study, we sequenced the genome of E. floccosum (CGMCC (F) E1d), and performed comparative genomic analysis with other dermatophytes. It is revealed that E. floccosum owns the largest genome size and similar GC content compared with other dermatophytes. A total of 7565 genes are predicted. By comparing with the closest species N. gypseum, our study reveals that number and structure of adhesion factors, secreted proteases and LysM domain might contribute to the pathogenic and ecological traits of E. floccosum. Mating genes is also detected in genome data. Furthermore, we performed AFLP analysis trying to discuss intraspecific differences of E. floccosum, but no significant relationship is found between genotype and geographical distribution. Upon above, our study provides a deeper understanding and strong foundation for future researches about E. floccosum.Keywords
