[Histochemical changes in Brugia malayi microfilariae-infected Anopheles sinensis]

Histochemical changes in normal and Brugia malayi microfilariae-infected Anopheles sinensis were observed using histochemical technique. The results showed that the activity of alkaline phosphatase (AKP) and acid phosphatase (ACP) and the content of glycogen and basic protein in Brugia malayi microfilariae-infected Anopheles sinensis were less obviously than those of the normal control. Esterase (EST) activity was reduced slightly and acetylcholinesterase (AChE) remained no change in infected mosquitoes compared with the normal control. It is suggested that the development of filaria larvae in vector mosquitoes has selective effect on their biochemical metabolism.
