Abstract

Six cases of disseminated intravascular coagulation in the horse are reported. They were characterised clinically by severe subcutaneous oedema of the head and neck, and clinocopathologically by abnormal partial thromboplastin and prothrombin times, a thrombocytopaenia and an increase in fibrin degradation product concentrations. Various aetiologies played a role in the pathogenesis of the condition including African horsesickness, babesiosis, lymphosarcoma and verminosis.
