Seroprevalence of PPR Virus in Pre- and Post-Vaccinated Sheep and Goats of Saurashtra Region of Gujarat

Abstract

The seroprevalence study of peste des petits ruminants (PPR) in sheep and goats was carried out in 5 districts of Saurashtra region of Gujarat state. A total of 828 (prevaccinated) and 423 (postvaccinated) serum samples from sheep and goats were screened for PPR specific antibodies using PPR specific c-ELISA. Overall seroprevalence of PPR was found to be 53.86 (446/828) and 72.34 (306/423) % in pre- and post-vaccinated small ruminants, respectively. Overall pre-/post-vaccinated seroprevalance rates were highest in Bhavnagar district (83.89/96.30 %), followed by Surendranagar (73.61/77.78 %), Amreli (56.25/83.33 %), Jamnagar (32.22/43.33 %) and Rajkot (27.78/64.44 %) districts. Pre and post vaccination seropositivity was noted higher in goats (59.90/78.75 %) than in sheep (35.75/52.43 %). Males in both the species (goats and sheep) showed higher seroprevalence (60.11/89.01 %) as compared to their female counterparts (52.09/67.77 %). Higher prevaccinated seroprevalence was recorded among age group of 1 to 2 years (63.41 %), followed by below 1 year age group (53.99%) and above 2 years of age group (44.20%).
