Coxiella burnetii seroprevalence in primiparous and multiparous ewes from southern Australia: a cross-sectional study

Abstract: Coxiella burnetii can cause reproductive disease in sheep and zoonotic Q-fever infections in humans. The role of infectious diseases including coxiellosis in causing poorer reproductive performance of primiparous ewes is not well studied. The aim of this study was to determine if natural exposure to C. burnetii is associated with poor reproductive performance of primiparous ewes and compare seroprevalence of primiparous and multiparous ewes. Coxiella burnetii seroprevalence was 0.08% (95% confidence interval 0… Show more

“…Abortions, stillbirths and polyarthritis associated with Chlamydia pecorum were identified in a subset of farms from WA 27, 30 . Exposure of ewes to Toxoplasma gondii , 37 Neospora caninum 25 and Coxiella burnetii 26 were identified on farms in this study, but there was no evidence that these were important contributors to foetal and lamb mortality in these flocks. Further investigations using data from this study will include multivariable analysis to evaluate the relative importance of different pathogens on reproductive performance.…”

“…Blood samples were collected for maiden and mature ewes as previously described 25, 26 . Briefly, blood samples were collected for all maiden ewes at five time‐points: pre‐mating, scan 1, scan 2, pre‐lambing (approximately 140 days from the start of mating) and lamb marking.…”
