ABSTRACT
Anaplasma ovis infection is known to occur in elk experimentally, but without clinical signs or significant clinicopathologic changes. An elk farm in southern Indiana experienced the death of 3 neonates. Gross findings suggested hemolytic anemia as the cause of death. Splenic impression smears revealed numerous intra-erythrocytic parasites compatible with Anaplasma spp. Products of a semi-nested PCR targeting the msp4 gene of A. ovis were sequenced and had 100% identity with published A. ovis sequences. Given the clinical presentation, vertical transmission of A. ovis was suspected. Pathologic and molecular findings confirmed that natural A. ovis infection occurred in an elk calf.
