Clostridium infection (jisizheng) in yaks in Qinghai, China.
Since the mid-1980s, outbreaks of a disease characterized by a sudden onset, acute deaths and extensive haemorrhages in the viscera and digestive tract of yaks have been prevalent in Qilian, Qinghai, China. The disease is known as jisiheng by local people. Virulent Clostridium perfringens type A and Clostridium haemolytica were isolated from yaks that had died of jisizheng. In 1996 and 1997, yaks were immunized with a polyvalent inactivated vaccine against C. perfringens and with an inactivated vaccine against C. haemolyticum, and this prevented the occurrence of jisizheng.
