This study reports the epidemiological, pathological and mycological findings of cutaneous pythiosis in cattle in southern Brazil. 23 calves, that were kept next to a river with extensive marshy regions, presented ulcerated cutaneous lesions in thoracic and pelvic limbs, sometimes extending to the ventral thoracic region. Histopathological examination revealed multifocal pyogranulomas in the superficial and deep dermis. The Grocott-Methenamine silver, immunohistochemistry anti-, ELISA serology and molecular characterization demonstrated the agent in these cases.
本研究报告了巴西南部牛皮肤腐皮病的流行病学、病理学和真菌学研究结果。23头犊牛饲养在有大片沼泽地区的河流附近，其胸肢和盆腔肢出现溃疡性皮肤病变，有时病变会延伸至胸前腹侧区域。组织病理学检查显示，浅表和深部真皮有多灶性脓性肉芽肿。Grocott六胺银染色、免疫组织化学、ELISA血清学和分子特征鉴定在这些病例中均证实了病原体的存在。
