An epizootic of an acutely fatal enteric disease in a colony of squirrel monkeys (Saimiri sciureus) was attributed to infection by Yersinia pseudotuberculosis serotype III. Of a total adult population of 96 animals at risk, there were six fatal cases of yersiniosis. Serological evaluation of the colony just after the outbreak ended revealed that 22 of 60 monkeys tested (37%) had significant antibody to Y. pseudotuberculosis (microagglutination titer of greater than or equal to 1:80) but did not have clinical disease. The outstanding pathological lesions noted in dying monkeys were acute, purulent, necrotic and focal enteritis primarily affecting the jejunum and ileum and focal hepatic necrosis and abscessation. Y. pseudotuberculosis was isolated from the organs of two of the dying monkeys. Using cold enrichment techniques, Yersinia was also isolated from the feces of two apparently healthy monkeys (both seropositive), from the spleen of a monkey dying of other causes, and from the colon contents of a stillborn squirrel monkey baby. All isolates had the same biotype and serotype. An episode of abortions was associated both temporally and spatially with the fatal cases of yersiniosis, and Y. pseudotuberculosis was cultured from the uterus of two of the dying monkeys, suggesting that yersinia infection may be associated with abortion, as well as with enteric infection, in these animals.
松鼠猴（松鼠猴属）群体中一场急性致命性肠道疾病的流行被归因于III型假结核耶尔森菌感染。在96只处于危险中的成年动物总数中，有6例耶尔森菌病死亡病例。疫情结束后对该群体进行的血清学评估显示，在检测的60只猴子中，有22只（37%）对假结核耶尔森菌有显著抗体（微量凝集效价大于或等于1:80），但没有临床疾病。在濒死猴子身上发现的突出病理病变是急性、脓性、坏死性和局灶性肠炎，主要影响空肠和回肠，以及局灶性肝坏死和脓肿形成。从两只濒死猴子的器官中分离出了假结核耶尔森菌。使用冷增菌技术，还从两只看似健康的猴子（均为血清阳性）的粪便、一只死于其他原因的猴子的脾脏以及一只死产松鼠猴幼崽的结肠内容物中分离出了耶尔森菌。所有分离株具有相同的生物型和血清型。一次流产事件在时间和空间上都与耶尔森菌病的致命病例相关，并且从两只濒死猴子的子宫中培养出了假结核耶尔森菌，这表明耶尔森菌感染在这些动物中可能与流产以及肠道感染有关。
