Seroprevalence of the Cattle Leptospirosis in South Gujarat Region of India

To evaluate the serological findings of cattle Leptospirosis which is a zoonotic disease with worldwide distribution caused byLeptospirainterrogans. It is usually mild and often subclinical in cattle but it may lead to higher incidence of abortion, stillbirth, infertility, mastitis, weak progeny and decreased milk production in cattle. 676 cattle serum samples were collected during 2008-2011 and stored at -20 °C. All the collected serum samples were subjected to Micro-agglutination test (MAT) and Real time polymerase chain reaction (PCR) tests for leptospirosis.A total 676 cattles were included in present study from which 195 (29%) samples were positive by MAT and 75 (12%) positive by Real time PCR. 21(3%) samples were positive by MAT and PCR both tests.40% cattle detected as carrier of Leptospiraorganism in present study. So cattle act as a maintenance host for leptospirosis in this geographical area. The combined laboratory methods for Leptospiradiagnosis enable the Veterinarian officers to assure their decisions. Further investigation on physiological adaptation of cows as a host of this organism must be supported for studying and creating new preventive strategies.
