摘　　要：To investigate the infection of Haemophilus parasuislin some regions of Sichuan Province, indirect hemagglutination from 2006 to 2008 was tested by Haemophilus parasuis antibody, and 1 062 serum samples from 10 different regions and sources in Sichuan Province were also examined. 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.To investigate the infection of Haemophilus parasuislin some regions of Sichuan Province, indirect hemagglutination from 2006 to 2008 was tested by Haemophilus parasuis antibody, and 1 062 serum samples from 10 different regions and sources in Sichuan Province were also examined.
