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

The results showed that astragalus polysaccharide （APS）, epimedium polysaccharide （EPS）, Chinese angelica polysaccharide （CAPS）, propolis flavone （PF）, and astrogalosides （AS） promoted IL-2 mRNA levels in T lymphocytes in vitro and in vivo to differing degrees, and the level of IL-2 mRNA induced by propolis polysaccharide （PPS） in vitro was higher than that induced by the control, which differed from that of PPS in vivo.展开更多
The known mycoplasmas isolated from goats and sheep were listed. The pathogenicity of these mycoplasmas and their effects during occurrence of mycoplasmosis were summarized.
