Prevalence of Peste-des-petits-ruminant virus antibodies in cattle, buffaloes, sheep and goats in India.

Abstract

The present study describes the prevalence of Peste-des-petits-ruminant virus (PPRV) antibodies in cattle, buffaloes, sheep and goats carried out during the period 2011 using the serum samples randomly collected from different villages of five states of India. A total of 1,498 serum samples [n = 605 (cattle); n = 432 (buffaloes); n = 173 (sheep); n = 288 (goats)] were collected from 52 districts in five states (Andhra Pradesh, Gujarat, Jammu and Kashmir, Maharashtra and Rajasthan) of India and were screened for PPRV-specific antibodies by using PPR monoclonal antibody-based competitive ELISA kit. Analysis of 1,498 samples indicates that an overall seroprevalence of 21.83 % with 11.07 % in cattle, 16.20 % in buffaloes, 45.66 % in sheep and 38.54 % in goats. This report presents the results of PPRV-specific antibodies in situations where the subclinical, inapparent or nonlethal or recovery of infection was suspected in cattle, buffaloes, sheep and goats. The presence of PPRV antibodies demonstrate that bovines are exposed to PPRV infection and it implies the importance of cattle and buffaloes as subclinical hosts for the virus besides widespread presence of the disease in sheep and goats. Further, the study showed that the prevalence of PPRV antibodies in apparently healthy livestock under natural situation, 21.83 % of the animals were protected from PPRV re-infection. This inturn help in the implementation of disease control strategies such as vaccination in that particular geographical area.
