An investigation on the prevalence of peste des petits ruminants in the camels of Sindh, Pakistan

AbstractThe present study investigated the status of peste des petits ruminants (PPR) for the first time in the camels of Pakistan. The samples were collected from the camel residing area of Sindh, Pakistan, and analyzed for breeds (Dhatti and Larri), districts (Tharparkar and Umerkot), age (young, adult, and old), and sexes (male and female). The sera samples (n = 200) were analyzed for the detection of antibodies using a competitive enzyme-linked immunosorbent assay (cELISA). Moreover, the nasal and fecal samples were screened for the PPR virus. Finally, the positive nasal and fecal samples were validated using reverse transcriptase-polymerase chain r eaction (RT-PCR) and immunocapture enzyme-linked immunosorbent assay (Ic-ELISA). The cELISA results showed an overall prevalence of 8.5% PPR in the study area. The camels of Tharparkar (10.9%; 95% confidence interval (CI) 9.2–12.9) showed higher seroprevalence of PPR antibodies than those of Umerk ot (5.5%; 95% CI 4.1–7.2). Moreover, the Larri breed exhibited slightly greater resistance against the disease, because the camels of Dhatti breed (9.0%; 95% CI 7.5–11.0) exhibited a numerically higher (p  > 0.05) seroprevalence of PPR in comparison with those of Larri breed (7.9%; 95% CI 6.4–9.9). Furthermore, the young and old camels were more susceptible to the disease attack, because the adults (6.3%; 95% CI 5.0–7.8) exhibited significantly (p <  0.05) lower prevalence rate than the young (9.2%; 95% CI ...
