Acute fatal infection with Pseudomonas pseudomallei caused pneumonia, placentitis and endometritis in a pregnant cow. Pneumonia was also present in the foetal lung. Mononuclear cell response with extensive karyorrhexis occurred in maternal and foetal lung and the same cellular pathology, but with diffuse distribution, was responsible for plaques on the endometrium. A more chronic disease with encapsulated caseous lesions in the lung, together with arthritis, occurred in a bull on the same property. Nutritional and physical stress caused by a flood were thought to be predisposing factors. An unusually wet summer with prolonged flooding apparently provided suitable environmental conditions for saprophytic growth of Ps. pseudomallei in an area far south of the region in which infection of animals with this organism commonly occur.
孕牛感染类鼻疽假单胞菌导致急性致命感染，引发肺炎、胎盘炎和子宫内膜炎。胎儿肺部也出现了肺炎。母胎肺部均出现了伴有广泛核碎裂的单核细胞反应，同样的细胞病理学变化（但呈弥漫性分布）导致了子宫内膜上的斑块形成。同一养殖场的一头公牛出现了一种更为慢性的疾病，肺部有包膜干酪样病变，并伴有关节炎。洪水造成的营养和身体应激被认为是诱发因素。异常潮湿且洪水持续的夏季显然为类鼻疽假单胞菌在该地区以南很远的一个通常不会感染该病菌的区域进行腐生生长提供了适宜的环境条件。
