In this study, we report an abortion outbreak in a ruminant herd consisting of goats, sheep, and cows, with scenarios in two consecutive years. In early 2017, abortions occurred in ∼70% of goats and 66% tested positive for Coxiella burnetii (C. burnetii) and 40% of goats were positive for Chlamydophila abortus (C. abortus). In February 2018, the same herd reported an abortion rate of 75%, with 55% positive for C. burnetii, 36% for C. abortus, and 22% for Toxoplasma gondii. Six goat milk samples were positive for C. burnetii by molecular analysis. Three family members were positive for C. burnetii. C. burnetii could be considered as the main cause of abortions in the first and second year. Animals that undergo an infection and abortion are prone to secondary infections. Vaccination or other rapid interventions should be initiated to protect animals and humans.
