associated proliferative abomasitis in a roan antelope.

A 2-y-old, intact male roan antelope () was submitted for routine postmortem investigation after a prolonged history of diarrhea and weight loss. The abomasal mucosa was diffusely thickened and corrugated. Abomasal gland hyperplasia was associated with abundant apical organisms consistent with spp. Genomic DNA was extracted from abomasal and intestinal contents and subjected to PCR using primers specific for the 18S rRNA gene of spp., followed by Sanger sequencing. The sequence was >99% homologous to -associated proliferative abomasitis has not been reported previously in a captive hippotraginid, to our knowledge.
