Abstract

Evidence is presented for the isolation and characterization of Anaplasma avis in both indigenous (Korean) and exotic goats imported from Australia. These studies were carried out in response to epidemic scenario whereby farmers reported noticing what was described as a mysterious disease characterized by anemia, anorexia, general malaise and a significant morbidity and mortality rate in both types of goat breeds. The syndrome consistent with caprine anaplasmosis was associated with an intraerythrocytic agent occuring in single initial bodies characteristically surrounded by a single-layered membrane whereas the marginal body was typically surrounded by a double-layered membrane. The identity of the etiologic agent was confirmed as Anaplasma avis by light and ultrastructural microscopy.
