A case of tinea corporis caused by Microsporum gallinae was found in 2011 in Okinawa, located in the southern part of Japan. The patient was a 96-year-old, otherwise healthy, Japanese man, who had been working as a breeder of fighting cocks for more than 70 years. He was bitten on his right forearm by one of the cocks and a few weeks later, two erythematous macules appeared on the right forearm, accompanied by a slight itchy sensation. While the first isolate of this dermatophyte was recovered from the region by Miyasato et al. in 2011, it was not obtained from the same fighting cock owned by the patient. However, frequent exchanges of fighting cocks and special domestic breeds of chickens related to fighting, mating, and/or bird fairs are common among the fans and breeders. We investigated 238 chickens and 71 fighting cocks in Okinawa and in the suburbs of Tokyo (Chiba, Tokyo, Ibaraki, and Sizuoka). One isolate of M. gallinae from a fighting cock in Chiba Prefecture in the Tokyo metropolitan area exhibited a different genotype, with a single base difference from the patient isolate based on the internal transcribed spacer 1-5.8s-ITS2 regions (ITS1-5.8S-ITS2) of the ribosomal RNA gene sequence. The isolation of M. gallinae from a fighting cock on the mainland of Japan is the first such finding in animals in our country.
2011 年在日本南部的冲绳县发现了一例由鸡马拉色菌引起的体癣。患者为 96 岁的日本男性，身体健康，他从事斗鸡饲养工作已超过 70 年。他的右前臂被一只斗鸡咬伤，数周后，右前臂出现两个红斑，伴有轻微瘙痒感。虽然 Miyasato 等人于 2011 年从该患者身上分离出了这种皮肤真菌的第一个菌株，但它并非来自患者所拥有的同一只斗鸡。然而，斗鸡爱好者和饲养者之间经常会有斗鸡和特殊的与斗鸡有关的国内品种鸡的交换、交配和/或鸟类展览会。我们在冲绳和东京都郊区（千叶、东京、茨城和静冈）调查了 238 只鸡和 71 只斗鸡。从东京都地区千叶县的一只斗鸡中分离出的一株鸡马拉色菌表现出不同的基因型，与患者分离株相比，核糖体 RNA 基因序列的内部转录间隔区 1-5.8s-ITS2 （ITS1-5.8S-ITS2）区域仅存在一个碱基差异。从日本本州的斗鸡中分离出鸡马拉色菌是我国首次在动物中发现该菌。
