Abstract
The aim of the present study was to examine the prevalence of leptospiral antibodies against serovars of L.interrogans, L.icterohaemorrhagiae, L.grippotyphosa, L.canicola, L.pomona and L.autumnalis among domestic animals and Humans in and around Namakkal. The serovars used in this study were chosen because of their clinical importance in human disease. Blood samples were received from clinically ailing human patients attending various hospitals, with the history of fever, myalgia, headache, nausea, conjunctival effusion, oliguria and disturbed sleep. Data relating to the illness were collected from the patients or their relatives through questionnaires. Blood samples were also collected from apparently healthy individuals who had associated with dogs. A sero-prevalence of 47.4% to 51.6% patients was found to be positive for Leptospirosis in Namakkal, Tamilnadu. The main serogroups identified in human cases are also found in animals (icterohaemorrhagiae and autumnalis). The maximum (MAT) titres observed were 1:640 (autumnalis) and 1:320 (icterohaemorrhagiae). Notably, the dominant serovar icterohaemorrhagiae is associated with most cases of weil’s disease in humans and dogs.
