Heartwater in Angora goats. II. A pathological study of artificially infected, treated and untreated goats.

Pathological lesions in untreated Angora goats infected with the Ball3 strain of Cowdria ruminantium corresponded with those previously reported. A severe nephrosis was the most prominent pathological lesion in the animals treated after the 1st day of the febrile reaction. Renal ischaemia appears to be central to the pathogenesis of the kidney lesions.
