N2 - Following a routine necropsy of a bovine fetus aborted at 5 months of gestation, placenta, fetal tissue samples, and stomach contents were subjected to a number of laboratory tests. Staphylococcus warneri was isolated in pure culture from the lung, liver, and stomach contents, whereas the placenta yielded S. warneri and a number of contaminants. Gross evaluation of agar plates showed predominant colonies to be morphologically consistent with those of S. warneri and the identity of the agent was further confirmed on a Trek Diagnostic Systems Sensititre, gram-positive identification (GPID) plate. Microscopic evaluation of fetal tissue sections showed extensive necrotizing lesions of the tongue, lung, and placenta in which there were numerous coccoid shaped gram-positive bacteria with morphology consistent with Staphylococcus spp. These results provide strong diagnostic evidence of S. warneri as a possible cause of bovine abortion and suggest there should be further investigations into the abortivirulence of this agent.
