An outbreak of Salmonella enterica serotype Choleraesuis enteritis occurred in two juvenile goitered gazelles and an adult Malayan tapir over a period of 5 wk at the Minnesota Zoo. Diagnosis was made postmortem on one gazelle and one tapir, and a second gazelle was diagnosed via fecal culture. The death of the tapir was attributed to S. enterica serovar Choleraesuis septicemia, while salmonellosis was considered to be a contributing factor besides ostertagiasis for the death of one goitered gazelle and for the diarrhea of another goitered gazelle. A third gazelle became ill in the same time period, but Salmonella infection was not confirmed by culture. All exhibited the clinical signs of profuse, watery diarrhea. The gazelles developed a protein-losing enteropathy, and the tapir showed signs of sepsis and endotoxemia. Serotyping and pulsed-field gel electrophoresis revealed the Salmonella isolates to be indistinguishable from each other. One year prior to this outbreak, Salmonella sp. was cultured from a Visayan warty pig (Sus cebifrons) housed in the same building as the tapir. After further investigation into the outbreak, spread of this pathogen was speculated to be associated with human movement across animal areas.
在明尼苏达动物园，5周内两头幼年鹅喉羚和一头成年马来貘爆发了肠炎沙门氏菌肠炎。对一头鹅喉羚和一头貘进行了死后诊断，另一头鹅喉羚通过粪便培养确诊。貘的死亡归因于肠炎沙门氏菌败血症，除奥斯特他线虫病外，沙门氏菌病被认为是一头鹅喉羚死亡和另一头鹅喉羚腹泻的一个促成因素。第三头鹅喉羚在同一时期发病，但培养未确诊沙门氏菌感染。所有动物均表现出大量水样腹泻的临床症状。鹅喉羚出现了蛋白丢失性肠病，貘表现出败血症和内毒素血症的症状。血清分型和脉冲场凝胶电泳显示，分离出的沙门氏菌彼此无法区分。此次疫情爆发前一年，在与貘同一栋楼饲养的菲律宾疣猪（Sus cebifrons）中培养出了沙门氏菌。对此次疫情进行进一步调查后，推测该病原体的传播与人员在动物区域之间的流动有关。
