Hemorrhagic septicemia is an acute pasteurellosis, which occurs notably in cattle and water buffalo, and to lesser degrees in other ruminants as well as other animals. It is caused by Pasteurella multocida bacteria, and can be rapidly fatal.[1] It is "characterized by a sudden onset of high fever, dyspnea, salivation, hot painful subcutaneous swellings and submucosal petechiae and death in about 24 hours."[2]
