Hemorrhagic septicemia and the greater economic impact of HS. Hemorrhagic septicemia Haemorrhagic septicaemia is one of the most economically important pasteurelloses. Haemorrhagic septicaemia in cattle and buffaloes was previously known to be associated with one of two serotypes of "P. multocida": Asian B:2 and African E:2 according to the Carter-Heddleston system, or 6:B and 6:E using the Namioka-Carter system. The disease occurs mainly in cattle and buffaloes, but has also been reported in goats ("Capra aegagrus hircus"), African buffalo ("Syncerus nanus"), camels, horses and donkeys ("Equus africanus asinus"), in pigs infected by serogroup B, and in wild elephants ("Elephas maximus"). Serotypes B:1
Equus lambei Furthermore, evidence from "E. lambei" mtDNA now proves that modern horses are not so far removed from their ancient ancestors. Many scientists believe that a good argument can be made that "E. caballus", too, should receive protection as a form of native wildlife in North America. However, this topic is still highly debated by wild horse management agencies. This debate has significant implications to wildlife management in North America, including protection and conservation for modern species. Equus lambei Equus lambei (common names include Yukon horse, and Yukon wild horse) is an extinct species of the genus "Equus". "Equus lambei" ranged
