Salmonellosis in gerbils induced by nonrelated experimental procedure.
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.
