Abstract	A serological study on canine leptospirosis was conducted in healthy and suspected cases of (vaccinated and non-vaccinated) house dogs from urban areas of Tiruchirappalli district, Tamil Nadu. Totally 70 dogs blood samples were collected and tested for anti-Leptospira antibodies using MAT, 24 (34.3%) were positive. Leptospira spp. Serovar Grippotyphosa (11.4%), Canicola (10%) and Icterohaemoragiae (8.6%) has found to be higher predominant in urban areas, which includes the post-vaccinal titres <800 and titres of 800 or greater were classified as suggestive of acute/current infection. Amongst 17 suspected cases of clinical leptospirosis, 12 (70.6%) were seropositive which is 83.3% of the animals were vaccinated and in healthy house dogs 12 (22.8%) of 53 were seropositive and 50% of healthy dogs only vaccinated. Only 7.1% Leptospira serovar canicola and Icterohaemoragiae was identified as vaccinal serovars against vaccinated dogs with titre value 1:400 or below.
