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.
