1975 ~ 1985年在牛系统性真菌病中发现9例播散性毛霉菌病，占尸检病例的1.3%，占全身性真菌病的20.0%。在肺（3头牛）、心脏（2头牛）、肝脏（2头牛）、脾脏（1头肉牛）、肾脏（1头牛）、中枢神经系统（1头牛）和淋巴结（1头牛）中发现了播散性病变。组织学检查显示肉芽肿性病变、坏死灶（包括梗死）和血栓性脉管炎伴接合菌菌丝和中性粒细胞反应。肝脏中发现带有小行星体的肉芽肿病变。从消化器官中发现的原发性病变（4例来自前胃或皱胃，1例来自舌）建立转移灶。1例为子宫毛霉菌病，其余3头牛均未发现原发病变。4例消化道毛霉菌病合并呼吸道曲霉菌感染。所有9头牛均存在易感性疾病。有6头牛表现出长期虚弱状况。4头牛出现贫血，2头牛出现白细胞减少，1头牛出现淋巴细胞减少。
Nine cases affected with disseminated mucormycosis (1.3% of all autopsy cases and 20.0% of systemic mycosis) were found among bovine systemic mycosis examined from 1975 to 1985. The disseminated lesions were found in the lungs (3 cattle), heart (2 cattle), liver (2 cattle), spleen (1 beef cattle), kidneys (1 cattle), central nervous system (1 cattle) and lymph node (1 cattle). Histological examination revealed granulomatous lesions, necrotic foci including infarcts, and thromboangiitis with the hyphae of a member of the Zygomycetes and neutrophil reaction. Granulomatous lesions with asteroid bodies were found in the liver. Metastatic foci were established from the primary lesions found in the alimentary organ (4 from the forestomach or abomasum and 1 from the tongue). One case resulted from uterine mucormycosis, and no primary lesion was found in the other 3 cattle. Complicated infection with respiratory aspergillosis occurred in 4 cases with alimentary mucormycosis. All of the 9 cattle had predisposing disorders. Six cattle had been manifested with prolonged debilitating conditions. Anemia was present in 4, leukopenia in 2 and lymphopenia in 1 cattle.
