General Description

Infectious, non contagious, rickettsial disease of domestic and wild ruminants found in parts of Africa infested by Amblyomma - Bont ticks (Genus). (B101

Clinical signs:

  • The disease presentation forms are: (B101)
    • Acute: Animals show anorexia and severe CNS signs. (B101)
    • Peracute: Animals develop high fever followed by CNS signs.  (B101)

In Elephants:

Loxodonta africana - African Elephant

Clinical signs:

  • Frequent urination, restlessness, weakness of the hindquarters and frequent falls; death (J3.133.w3)
Further Information Information is available from a single case report.

Diagnosis/ Investigations:

  • Impression smears from the brain, stained with Giemsa, showed "clusters of dark blue, coccoid intracytoplasmic bodies in the endothelia of the brain". These were identified by light microscopy as Cowdria ruminatum. (J3.133.w3)

Gross pathology:

  • Thoracic cavity: Serohaemorrhagic exudate with fibrin. (J3.133.w3)
  • Heart: Ecchymoses of the epicardium and atrioventricular surfaces. (J3.133.w3)
  • Abdominal cavity: Serohaemorrhagic exudate with fibrin. (J3.133.w3)
  • Gastrointestinal tract: Congestion of the serosal surface of the small and large intestines, and ulcers. (J3.133.w3)
  • Liver: Enlarged. (J3.133.w3)
