Hemorrhagic septicemia 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 and B:3,4 have caused a septicaemic disease
Equus scotti assigned fossils from the Anza-Borrego Desert in California, tentatively interpreted to represent "E. bautistensis", to "E. scotti". One of the reported locations farthest south in the Americas is Pali Aike National Park in Chile. Equus scotti Equus scotti (translated from Latin as Scott's horse, named after vertebrate paleontologist William Berryman Scott) is an extinct species of "Equus", the genus that includes the horse. "E. scotti" was native to North America and likely evolved from earlier, more zebra-like North American equids early in the Pleistocene Epoch. The species may have crossed from North America to Eurasia over the Bering land bridge
