Genotypes of Echinococcus Species from Stray Dog in Wasit /Iraq

Abstract

The dog tapeworm Echinococcus granulosus is a cosmopolitan parasite. The adult worms reside in the small intestine of their definitive hosts (dogs). In this study presents the results of a study of feces of 110 dogs from AL Kut center, AL - Numaniya, AL Hayy, Jassan, AL- Zubaydiya & AL- dubuni regions for Echinococcus granulosus, collected in from January 2022 to May 2022. Eggs of Taeniia spp. were found using copro-pcr methods. Based on the analysis of the nucleotide sequences of 40 egg samples, 22 samples were identified as E. granulosus. Based on the (cox1) gene, the G1, G2, G3, G5and G6 genotype was established, genotypes G1 and G3 of E. granulosus show that sheep strain and buffalo strain are unambiguously circulating in the region. These samples were deposited in the NCBI GenBank database. This study is considered the first to identify the genotype of Echinococcus spp. in Wasit/ Iraq.
