              Abstract 
 Aim:
              The aim was to study the epidemiology of human and animal 
              leptospirosis in Central and Northern Kerala, by isolation 
              techniques and serology. 
              Materials and Methods: Kidney tissues from 35 rodents (11 
              bandicoots and 24 rats), autopsy specimens from two canines, blood 
              from 15 canines and 30 human beings were subjected to isolation 
              trials for Leptospira. Sera from these animals and human 
              beings were screened for leptospiral antibodies by microscopic 
              agglutination test (MAT). 
              Results: Leptospira could be isolated from human blood 
              as well as from rodent kidney tissues. The MAT could detect the 
              presence of leptospiral antibodies in 54.54% of human sera, 36.36% 
              of dog sera and 21.42% of rodent sera. Pomona and Australis were 
              the most predominant serovars detected in man, dog, and rodents. 
              Tentative serotyping of the isolates by MAT revealed its identity 
              as Leptospira interrogans serovar Pomona. 
              Conclusion: Detection of common serovars of Leptospira 
              in man and animals by serology as well as isolation reiterates the 
              major role played by animals in the epidemiology of human 
              leptospirosis. 
              Keywords: canine, epidemiology, human, isolation, 
              leptospirosis, microscopic agglutination test, rodent.
