Abstract
India is endemic to bovine brucellosis, and there is a high potential for transmission of disease from ruminants to dogs. A total of 18 bitches belonging to five different breeds at different stage of abortion (30 days to 65 days of gestation) were selected for this study. Majority of them were showing abortion (88.89 per cent) at 45 to 65 days of the gestation. Microscopic examination of Stamp stained smear obtained from the aborted foetal stomach contents revealed red coccobacillary organisms suggestive of Brucella spp.in three cases. RBPT on paired sera samples on day of presentation and three weeks after abortion showed agglutination within four minutes in five out of 18 female dogs. DNA extracted from the aborted tissues of a RBPT positive Labrador dog yielded amplicons of 193 base pair specific for Brucella spp. on PCR. The results obtained from this study stress the need for screening dogs for canine brucellosis in the current brucellosis surveillance and control programmes.

Canine brucellosis is an infectious disease of dogs caused by Brucella spp. (B. canis, B. abortus, B. suis and B. melitensis) (Wanke, 2004)
A total of 18 female dogs with a history of abortion at different stages of gestation presented to the UniversityVeterinary Hospitals, Kokkalai and Mannuthy were selected for this study
Summary
India is endemic to bovine brucellosis, and there is a high potential for transmission of disease from ruminants to dogs. Canine brucellosis is an infectious disease of dogs caused by Brucella spp. Hollett (2006) opined that canine brucellosis is one of the major causes of abortion and infertility in dogs and possessed a potential health hazard to humans. The Center for Food Security and Public Health (CFSPH, 2018) reviewed that canine brucellosis could end the reproductive life of a breeding animal.
