Post outbreak profile of peste des petits ruminants (PPR) virus antibodies in relation with vaccination in recovered goats

Peste des petits ruminants (PPR) disease was confirmed in a herd of goats (n=45) at an organized form. The disease was controlled by administration of symptomatic treatment. Disease confirmation was done by detection of both antigen and antibodies using enzyme linked immuno-sorbent assay (ELISA). Following clinical recovery in diseased animals, all the animals were vaccinated with the PPR vaccine. Serum samples were collected with monthly interval and analyzed for the detection of antibodies against PPRV using competitive ELISA (cELISA). Mean percent inhibition (PI) values of all the goats post-vaccination ranged 61-85 at first month but remained 80-93 afterward. All the animals developed the antibodies titers one month post-vaccination and remained high even one and half year post-vaccination.
