Possible death of a buffalo calf (Syncercus caffer) due to suspected heartwater (Ehrlichia ruminantium) : clinical communication

Abstract

Rickettsial organisms resembling Ehrlichia ruminantium (the causative organism of heartwater) were demonstrated in brain smears and formalin-fixed brain sections derived from a buffalo calf that died on a private game reserve in northern KwaZulu-Natal. The possibility that the tick-free environment of a quarantine boma may have affected the calf 's immunity, is discussed. These findings suggest that monitoring heartwater in wild ruminants and making brain smears as a routine during post mortem evaluations of wild ruminants, should be encouraged.
