Summary 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.
