艺术体操运动员局部体位及体操毯的真菌群落组成分析

Fungal community composition on the rhythmic gymnast’s partial positions and gymnastic blankets

艺术体操运动员的手掌、足部(包括足跟和足尖-鞋腔)、以及体操毯的真菌群落组成是否存在潜在的卫生安全隐患,目前国内尚未见研究报道。本研究对37位艺术体操运动员手掌、足跟、和足尖-鞋腔以及体操毯进行了运动场现场采样,通过高通量测序、宏基因组分析、FUNGuild平台功能注释等进行研究分析。研究结果表明,在艺术体操运动员脚尖鞋腔中存在较多人体潜在的病原真菌,其优势属为常见皮肤真菌,如迈氏酵母Meyerozyma、毛癣菌Trichophyton和谷氏酵母属Guehomyces等,同时也存在新兴病原真菌,如皮假黑粉菌Coniosporium epidermidis和萨氏曲霉Aspergillus sydowi等。在体操毯中常见的皮肤真菌类群虽未被发现,但一类新兴病原真菌链格孢属Alternaria的相对丰度竟达到了50.90%,它们都在一定程度上会引起公共卫生的安全问题。

Fungal community on the palms and feet(including heel and toe tip-shoe cavity)of gymnastics athlete and gymnastics blanket,and its hidden danger to health safety has not been reported in China.Based on samples taken from different partial positions of 37 rhythmic gymnasts in spot venues,the cutaneous fungal community of gymnast body was investigated.The results of high-throughput sequencing,metagenomic analysis,and FUNGuild function annotation showed that the diversity of fungal community in athlete’s toe shoe cavity was the most abundant,while that in heel,palm as well as gymnastic carpet was lower.In toe shoe cavity the common skin fungi,such as Meyerozyma,Trichophyton and Guehomyces were dominant.Relative abundance of the genus Alternaria,an emerging pathogenic fungi,reached 50.90%,which may cause safety problem of public health to some extent.
