Serological prevalence of ovine and caprine chlamydophilosis in Riyadh region, Saudi Arabia

Abstract

The serological prevalence of Chlamydophila abortus was determined in 399 sheep and 171 goats in Riyadh region, Saudi Arabia, using the CHEKIT enzyme-linked immunosorbent assay (ELISA). Sera from 30 (7.52%) sheep and 59 (34.50%) goats were positive for anti-C. abortus antibodies. Higher serological prevalence and antibody concentration (percent optical density) was recorded in goats as compared to sheep. In both species, the prevalence of chlamydophilosis was markedly higher in female than male animals. Statistical analysis showed highly significant species and sex effects on prevalence. Further studies should be undertaken to assess the role of chlamydophilosis in ovine and caprine abortion in Saudi Arabia, its economic impact and the need for implementing effective control strategies such as vaccination.
