The study from four states have found accidently that Aspergillus fumigntus and Clostridium were possibly involved in etiology of HBS,since they were detected in all samples of feed,gastrointestinal(GI) contents,GI wall,lymph nodes and blood collected from HBS.
而从俄勒冈大学的实验中意外地发现,在HBS患病奶牛和对照奶牛的饲料、胃肠内容物、胃肠壁、淋巴结和血液等病料中都检测到烟曲霉菌和梭菌,怀疑这两种微生物可能是HBS的致病病原。
