A dairy herd (102 cattle) which had been enrolled under a paratuberculosis control program for two years utilizing a complement fixation test (carbohydrate antigen) and intradermal skin test (johnin PPD) was subjected to two further herd tests and followed to slaughter to determine infection status by culture and histology. Mycobacterium paratuberculosis infection was demonstrated in 37 of the animals of which only five were considered reactors on the basis of the last two herd tests applied. Cultural and histopathological evaluation indicated the testing procedures had eliminated heavily infected animals. The limitations of these testing procedures under free stall housing conditions are discussed.
一个奶牛群（102头牛）参加副结核病控制计划已有两年，该计划采用补体结合试验（碳水化合物抗原）和皮内皮肤试验（副结核菌素纯蛋白衍生物），之后又进行了两次全群检测，并跟踪至屠宰，以通过培养和组织学确定感染状况。在37头动物中检测出副结核分枝杆菌感染，其中根据最后两次全群检测结果，只有5头被视为反应动物。培养和组织病理学评估表明，检测程序已淘汰了重度感染的动物。本文讨论了在自由牛舍条件下这些检测程序的局限性。
