Incidence of listeriosis in farm chinchillas (Chinchilla laniger) in Croatia

Listeriosis is an infectious disease of domestic and wild animals coused by Listeria monocytogenes, and is transferable to humans. There are two clinical forms of listeriosis: septicemic and encephalitic. This paper deals with two cases of listeriosis in chinchillas (Chinchilla laniger), originating form a farm in the County of Međimurje in Croatia, and were pathomorphologically and bacteriologically examinated. This particular breed consisted of 64 chinchillas, 34 of which have died due tue same symptoms. History reveals that animals had suffered loss of appetite, and abortion occurred about 5 days before dead. Gross lesions included general anaemia and cachexia. Whithis-grays nodules the size of millet grain or little larger were noticed along the capsule of liver, serosa of colon and in mesenterial lymph nodes. Numerous vaiably-sized granulomas in liver, intestines, lymph nodes and kidneys, with no special pattern, were observed histopathologically. They consisted of necritic cells with somewhat more granulocytes in the center and scattered individual giagantocytes. Bacteriological examination of liver specimens revealed Listeria monocytogenes in pure culture in both cases. This is the first description of listeriosis in chinchillas in Croatia.
