Abstract
Peste des petits ruminants (PPR) is endemic to Sudan. It is considered as a priority disease in the list of transboundary animal diseases (TADs). The aim of this study was to assess the reliability of the detection of PPR antibodies by a competitive enzyme-linked immunosorbent assay (cELISA) in naturally infected or vaccinated sheep. Sera were collected from 3,186 sheep from flocks located in six states of Sudan and additionally 100 sheep were vaccinated with a PPR homologous vaccine (produced locally) in a quarantine station. The percentages of PPR antibody-positive sera from the field varied between 72% and 100%, according to state. All sheep vaccinated in the quarantine station were PPR-seropositive. This study shows, first, that the percentages of PPR-seropositive animals were all very high, whether naturally infected or vaccinated. It also shows the reliability of the cELISA test used in this study.
