Comparison of Coxiella burnetii Shedding in Milk of Dairy Bovine, Caprine, and Ovine Herds

Median and quartile of the delay in days between the beginning of the study and the calving of the cows of the control herd (E), or of the infected herds (V, F, L), according to their shedding of Coxiella burnetii. The lines represent the greatest and least delay between parturition and wk 0. No significant difference was observed between the tested cows (V, F, L) and those shedding C. burnetii (V+, F+, L+).

Median and quartile of the delay in days between the beginning of the study and the lambing of the ewes of the control flock (Fi) or of the infected flocks. The lines represent the greatest and least delay between parturition and wk 0. No significant difference was observed between the tested sheep (B, M, H) and those shedding Coxiella burnetii (B PCR+, M PCR+, H PCR+).

Median and quartile of the delay in days between the beginning of the study and the kidding of the goats of the infected herds. The lines represent the greatest and least delay between parturition and wk 0. No significant difference was observed between the tested goats (T, R, D) and those shedding Coxiella burnetii (T+, R+, D+).
