The role of wild ruminants in the epidemiology of bovine petechial fever.

After experimental inoculation of Cytoecetes ondiri, the agent of bovine petechial fever (BPF), multiplication occurred in impala, bushbuck, Thomson's gazelles and wildebeest, as shown by infectivity studies and clinical findings. Similar attempts to infect one eland failed. As a sequel to this, blood and spleen samples were collected from four species of wild ruminants in an area where BPTF was endemic. Isolations of C. ondiri were made from three of five bushbuck, but not from any other species.
