Abstract:
The conditions of the mosquito-borne HBsAg were investigated with the RPHA method in Henan Province. The number of capture of Anopheles hyrcanus sinensis was small, and no HBsAg was detected from them. HBsAg was detected in both Culex pipiens pallens and Armigeres subalbatus and their positive rates of HBsAg were 10.3 and 4.6% respectively. The positive rates varied with different physiological conditions of mosquitoes, being 15.0, 7.2 and 7.5% respectively for fed, unfed and gravid females.With the digestion of the blood in the mosquito's stomach, most of the HBsAg was excreted in the feces gradually. This new finding of the transmission of HBsAg inside the mosquito's body has not been reported. The fact that HBsAg was not detected in eggs and larvae showed that it is not transmitted by eggs.
