An outbreak of salmonellosis in a gerbil colony was investigated. The clinical, bacteriologic, and pathologic findings are reported. Clinical signs included an occasional sudden death, depression, emaciation, dehydration, rough hair coat, and testicular enlargement. Not every sign was observed in every infected gerbil. At necropsy, 11 animals had lesions consistent with salmonellosis. Histopathologic lesions consisted of interstitial pneumonia, hepatic and splenic necrosis, meningitis, and suppurative orchitis. Splenic and intestinal amyloidosis were also noted. Salmonella, group D, was recovered from gerbil feces, a container in which adult mosquitos were reared, filarial inoculum, and a cockroach. An epizootiologic investigation led to salmonella-infected cockroaches as the possible source of animal contamination via mosquitos and the subsequent filarial inoculum.
对沙鼠群体中沙门氏菌病的一次爆发进行了调查。报告了临床、细菌学和病理学发现。临床症状包括偶尔的突然死亡、抑郁、消瘦、脱水、毛发粗糙以及睾丸肿大。并非每只受感染的沙鼠都出现了所有症状。尸检时，11只动物有与沙门氏菌病相符的病变。组织病理学病变包括间质性肺炎、肝脾坏死、脑膜炎和化脓性睾丸炎。还注意到脾和肠道淀粉样变性。从沙鼠粪便、饲养成年蚊子的容器、丝虫接种物和一只蟑螂中分离出D组沙门氏菌。一项流行病学调查表明，感染沙门氏菌的蟑螂可能是通过蚊子以及随后的丝虫接种物导致动物污染的源头。
