title: Idiopathic thrombocytopenia in Japanese black cattle.
abstract: A female Japanese Black cow showed hemorrhage under the mucous membrane of the eye conjunctiva and the vagina, and thrombocytopenia in peripheral blood. The clinical manifestations repeated spontaneously during long-term observation. The clinical findings were stable except for severe periodic bleeding. Prothrombin time, activated partial thromboplastin time and fibrinogen levels were normal. The anti-platelet antibody in the serum was analyzed by indirect platelet coagulation tests. Because the platelets in the micro-plate wells of the subject series showed coagulation up to 1:128, it was judged that anti-platelet antibody was present in the serum. A number of megakaryocytes were recognized in smear samples obtained from bone marrow of the scapula immediately after euthanasia. Therefore, this case was diagnosed as idiopathic thrombocytopenia.
