Pathological Investigations of Experimental Leptospirosis in Hamsters

Abstract

Forty-eight Syrian hamsters (Cricetus auratus), aged 1.5-2 months, were used in this study. Forty of the animals were infected with Leptospira interrogans serovar grippotyphosa by intraperitoneal route. Eight hamsters were given physiological saline solution by same route. A systematic necropsy was performed on 9 animals that died during the study period and on 31 animals that were euthanized on days 7, 14, 21 and 28 of the trial. Remaining 8 animals was necropsied on day 28 as control group. Macroscopically, the hamsters included in Group 1. presented with mild icterus and marked anaemia throughout the study period. The lungs were swollen and dark red coloured, and some of the cases displayed haemorrhagic lesions. In Group 2., the liver was swollen and dark red-coloured and the kidneys were swollen and pale. Groups 3. and 4. presented with multiple greyish white foci that varied in number, in the kidneys. Microscopically, Hematoxylin-Eosine (HE) staining in Group 1. demonstrated the presence of haemorrhages in multiple organs, including primarily the lungs, as well as degenerative alterations, necrosis and mild neutrophil leukocyte and mononuclear cell infiltrations in the liver, and degenerative changes in the kidneys. In Group 2., degenerative changes and mononuclear cell infiltrations in the liver were observed to be of greater intensity. In Groups 3. and 4., lesions were generally limited to the kidneys and findings related to interstitial nephritis were observed. The presence of the infectious agent was detected in all trial groups, by the silvering methods and Avidin-Biotin Complex Peroxidise (ABC-P) staining.
