Abstract:
Background:Echinococcosis is from animals to humans and cause cestode zoonoses. Genetic variations within of echonoccocus and their genotypes may cause a disease as well as can indicate transmission dynamics to human and pets. At present, there are no available data for the typing of echinococcosis isolated in MongoliaMaterials and Methods:A total of 50 human hydatid samples from collected from State Centre on Maternal and Child Health, Oncology Centre of Mongolia. All samples were examined by PCR using cox1. The PCR products with a molecular size of 578 bp were amplified from human hydatid samples. Also we used RFLP method.Results:Genotype and strains of E. multilocularis and Е. granulosus were identified by RFLP. PCR products were digested using Ssp I, Hind III, Bgl II endonucleases. PCR products were digested by Ssp I endonuclease we found E. multilocularis. PCR products were digested by Bgl II endonuclease. Two major bands were seen in human hydatid sample. The bands have molecular weight of 420 and 158 bp respectively. It was infected by E. granulosus G6. Digestion with Hind III revealed two major bands within samples from human hydatids. These bands have molecular weight of 168, 410 bp respectively. These samples were infected by E. granulosus G1. Most of E. granulosus materials obtained from human patients by surgery confirmed the presence of sheep strain G1 (Bowles and McManus, 1993 a & c). In 24 cases of human hydatid echinococcosis in Mongolia sheep strain was found to be infective to humans.Conclusions:1. Echinococcosis caused by E. granulosus, E. multilocularis in human.2. G1, G6 genotypes of E. granulosus found in human hydatids.
