dc.description.abstractA field study was conducted to determine serologically the aetiological role of Chlamydophila abortus in small ruminant abortion in northern and central areas of Taraba State, Nigeria. A total of 368 serum samples from aborted ewes and does were collected from 39 randomly selected villages in four Local Government Areas (LGAs) in the study area. The sera were tested for the presence of raised levels of Chlamydophila abortus antibodies using ELISA technique. Brucella-antibody test was also conducted as differential diagnosis to Chlamydophila abortus using the same technique. The prevalence of abortion in small ruminants in the study area was determined as a percent of breeding females in the sheep flocks and goat herds that were investigated. The result revealed an overall prevalence of 25.6% abortion in ewes and does over a two-year period. There was no significant (P>0.05) difference in the prevalence of abortion between sheep and goats. Fourteen animals tested positive for Chlamydophila abortus antibodies which gave a prevalence of 3.8%. Chlamydophila abortus-positive animals were detected in each of the four LGAs sampled. There was no significant (P>0.05) difference between sheep and goats in the prevalence of Chlamydophila abortus in this study. Brucella-antibodies were detected in nine animals in only one out of the four LGAs. The study has established for the first time, an evidence of chlamydial abortion in sheep and goats in northern and central areas of Taraba State. The higher prevalence and wider geographical spread of Chlamydophila abortus-related abortions compared to Brucella-related abortions indicated that Chlamydophila abortus may be a more important pathogen causing abortion in small ruminants in the study area than Brucella spp.en_US
