Disease resulting from infection by Zygomycetes fungi (including two groups of coenocytic fungal pathogens: the Mucormycota and the Entomophthoramycota) has been collectively referred to as zygomycosis. Clinical disease associated with both the Mucormycota and the Entomophthoramycota is rarely encountered in horses. Potentially life-threatening, mucormycosis is an angioinvasive disease that principally affects immunocompromised individuals. The order of Entomophthorales include two genera: Conidiobolus and Basidiobolus. The most common of these, Conidiobolus coronatus, typically causes chronic necrohaemorrhagic tumefactions in the nostrils, nasal passages and nasopharyngeal walls of immunocompetent equine hosts, most commonly seen in the south-eastern USA and parts of Australia. Infection by Basidiobolus ranarum is reported less frequently and usually causes solitary ulcerative skin lesions with pruritus. This short commentary intends to complement the accompanying review of conidiobolomycosis by summarising reported cases of mucormycosis and basidiobolomycosis in horses. Moreover, some new information regarding taxonomic challenges to traditional ‘Zygomycosis’ classification is presented.

除了分生孢子菌病 - 其他“接合菌病”

由接合菌属真菌（包括两组同卵型真菌病原体：毛霉菌门和虫媒菌门）感染引起的疾病统称为接合菌病。与毛霉菌门和虫霉菌门有关的临床疾病在马身上很少遇到。可能危及生命的毛霉菌病是一种血管侵袭性疾病，主要影响免疫功能低下的个体。Entomophthorales 目包括两个属：Conidiobolus 和 Basidiobolus。其中最常见的是Conidiobolus coronatus，通常会导致具有免疫活性的马宿主的鼻孔、鼻道和鼻咽壁出现慢性坏死性出血性肿胀，最常见于美国东南部和澳大利亚部分地区。感染者Basidiobolus ranarum的报道较少，通常会引起伴有瘙痒的孤立性溃疡性皮肤损伤。这篇简短的评论旨在通过总结报告的马毛霉菌病和担子菌病病例来补充伴随的分生孢子菌病综述。此外，还介绍了一些关于传统“接合菌病”分类面临的分类学挑战的新信息。
