Abstract
An Anaplasma was not recovered from 2 splenectomized calves at 17 days after A. ovis inoculation, but was recovered from 1 of the calves at 177 days after inoculation. In a 3rd calf exposed to A. ovis, an Anaplasma was recovered at 177 and 262 days after inoculation. The Anaplasma recovered from these calves was determined to be A. ovis on the basis of cross-infectivity trials, using A. marginale.
