The etiology of abomasal ulcers/tympany was investigated in 48 animals from 36 ranches in Wyoming and Nebraska. Results indicate that subclinical trace mineral deficiencies of copper and/or selenium exist in the range cattle in west central Nebraska and Wyoming. Etiological agents most frequently incriminated by bacteriologic cultures and/or histopathic examination were Clostridium perfringens and Campylobacter species. Histopathologic evaluation of abomasums revealed 31 of 38 cases contained abundant gram-positive bacteria associated with the damaged abomasal mucosa. Campylobacter-like organisms were demonstrated in 9 of 38 cases using the modified Dieterle stain. Clostridium perfringens was isolated in 14 of 38 cases, and Campylobacter jejuni was recovered from 5 of 38 cases.
对来自怀俄明州和内布拉斯加州36个牧场的48只动物的皱胃溃疡/气胀病因进行了调查。结果表明，在中西部内布拉斯加州和怀俄明州的放牧牛群中存在铜和/或硒的亚临床微量矿物质缺乏情况。通过细菌培养和/或组织病理学检查最常确定的病原体是产气荚膜梭菌和弯曲杆菌属。皱胃的组织病理学评估显示，38例中有31例含有与受损皱胃黏膜相关的大量革兰氏阳性菌。使用改良的迪特尔勒染色法在38例中的9例中发现了弯曲杆菌样生物体。在38例中的14例中分离出产气荚膜梭菌，在38例中的5例中分离出空肠弯曲杆菌。
