Abstract

Introduction. Giardiasis is one of the health problems in the world including Iran. To determine the biochemical and biological problems and also identification of various strains, it is essential to obtain PURE CULTURE and then mass production of GIARDIA LAMBLIA. The goal of this study was to isolate this protozoa purely.Methods. GIARDIA LAMBLIA cysts were isolated from 50 stool samples by use of floating of a four - layer of sucrose method. The cysts were transfered to an inducing solution. Subsequently, they were cultured in a modified culture medium (TYIS-33). Following excystation of trophozoite and its multiplication, the parasite was caltured and purified.Findings. Excitation of trophozoite was observed in 40 samples (80 percent) from which 22 samples (55 percent) yielded PURE CULTURE. The doubling time was approximately 13hr and the peak of parasite was observed between third and fourth days.Conclusion. The proliferation and growth rate of GIARDIA LAMBLIA have enabled us to use this method widely. Cystein and ascorbic acid which are present in the induction solution, have a key role in excystation of trophozoite. Purification and passage of samples has facilitated the culture of this parasite in vitro. Therefore this method has yielded better results in comparison with other studies. This is probably due to a decrease in the amount of bovine bile or using different strains of GIARDIA LAMBLIA in the present study.
