Abstract
During 1983 and 1984, ileocecal lymph node specimens were obtained from clinically normal cattle at 76 US Department of Agriculture-inspected cull cattle slaughterhouses in 32 states and Puerto Rico. Mycobacterium paratuberculosis was isolated from the lymph nodes of 119 of 7,540 cattle. The prevalence of bovine paratuberculosis was 1.6% overall, with 2.9% in dairy culls and 0.8% in beef culls. The prevalence for females and males did not appear to differ significantly.
摘要
在1983年和1984年期间，从美国32个州和波多黎各的76家经美国农业部检查的淘汰牛屠宰场的临床正常牛身上获取回盲部淋巴结标本。从7540头牛的淋巴结中分离出了副结核分枝杆菌。牛副结核病的总体患病率为1.6%，其中奶牛淘汰牛的患病率为2.9%，肉牛淘汰牛的患病率为0.8%。雌性和雄性的患病率似乎没有显著差异。
