In order to determine Schistosoma mansoni infection rates in Biomphalaria tenagophila and B.straminea, low stringency polymerase chain reaction (LS-PCR) technique was used as a complementary method to light exposure technique.LS-PCR has already been standardized 3 Piece Full Bookcase Bed in our laboratory to detect the trematode DNA in B.glabrata.
Higher S.mansoni infection rates were detected using conventional method and LS-PCR.The parasite DNA profile was detected in both species after 7-day exposure to miracidia, using LS-PCR.This technique enables early detection of schistosomiasis transmission focuses, in endemic areas, before ORG STEVIA NATURAL the beginning of cercariae shedding.
