A 16-year-old Westphalian mare aborted a dead fetus at 7 months of gestation without prodromal signs. The chorioallantois was diffusely thickened and discoloured, with fibrinous plaques, congestion and haemorrhage. Small colonies of 1-μm, Gram-positive bacilli were scattered throughout the exudate overlying the chorionic epithelium, and within macrophages. Bacillus safensis was isolated from the fetal lungs and from a swab sample of the mare's uterus. This strain represents the first case of a B. safensis-associated equine abortion and the first case of any infection caused by this bacterium.
