Hemobartonella-like parasites in cynomolgus monkeys (Macaca fascicularis).
Red blood cell parasites were identified electron microscopically in five anemic adult female cynomolgus monkeys (Macaca fascicularis), two of which died during anemic episodes. Organisms typically were 0.3-0.5-micron round, oval, or reniform bodies on the surface or within vacuoles of erythrocytes. Based on their size, location in the erythrocyte, and internal ultrastructural features, organisms were classified as Hemobartonella-like. The relationship between the organisms and the anemias in these monkeys was unclear. This report adds rickettsial erythrocyte infections to the list of latent infections that can complicate research studies with cynomolgus monkeys.
