Serodiagnosis of leptospirosis in domestic animals and humans

2013

A total of 3430 serum samples from various animal species and humans were tested using microscopic agglutination test (MAT) to determinethe frequency of the important leptospiral serovars involved in animals and humans. The sera were screened against 14 serovars of pathogenic Leptospira interogans and 1 serovar of non-pathogenic Leptospira biflexa. Altogether, 441 (12.86%) of the tested serum samples were found to be positive serologically. Tested sera reacted to all 15 serovars used in this study. The most predominant serovar in cattle and sheep is hardjo (39.60% and 66.67%). However, in goat, buffalo and horse, the most frequent serovar detected is hebdomadis (30.00%, 32.58% and 57.14%). In dog, the most predominant serovar is bataviae (19.23%). In humans, the most predominant serovar is cynopteri (3.26%). Among all the samples tested, there were no positive samples from pig and cat. Domestic animals, rodents andpets can infect the environment or transmit the disease to human or other animals. This study showed that domestic animals could play a role in the epidemiology of leptospirosis and represents a threat topublic health.
