The results showed that the positive rate ranged from 2% to 30% with average of 10%. The positive rate varied with pigs at different ages, and especially that of 30-day-old to 70-day-old weaned piglets reached 25%. Thus, there were various infections of HaemophUus parasuis in some regions of Sichuan Province, and the statistic data provided a reference for effective prevention and control of Haemophilus parasuis in Sichuan Province.展开更多
