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 of the modern wild horse, including the domestic horse, "Equus caballus". Controversy still surrounds "E. lambei" and the divergence of other similar extinct horse species. Through examinations of the bones and teeth of "Equus lambei", many similarities can be seen with the modern horse "Equus caballus". There is also a strong resemblance to "E. lambei" in the metapodials of "E. caballus przewalskii" and the phalanges of "E. caballus lenensis" "." Metrical and morphological studies of horse teeth from the Bluefish Caves confirm the close similarity between "Equus lambei" with wild and domestic horses alive today. "E. lambei" is a "caballus"
