Risk of seroconversion to peste des petits ruminants (PPR) and its association with species, sex, age and migration

Abstract The present investigation included a detailed description of risk of PPR in small ruminants and its association with various host and environmental factors. A total of 432 serum samples comprising of 216 samples (108 sheep and 108 goats) from migratory and 216 samples (108 sheep and108 goats) from non-migratory flocks of sheep and goat were screened for PPR antibodies using competitive-ELISA. The overall seroprevalence of PPR in migratory flocks (33.79%) was significantly ( p p 12 months age group (39.58%) followed by 8–12 months (26.38%) and 4–8 months (20.83%) age group. On risk factor analysis, it was observed that at 95% confidence interval, odd ratio was higher in migratory (1.610) than non-migratory (0.612) flocks, in sheep (1.023) than goats (0.978), the value of odd ratio was higher in >12 months age group (2.490 and 1.828) as compared to 4–8 months and 8–12 months, respectively. The overall sex wise seroprevalence in males (33.33%) was significantly ( p
