Elazığ'da mezbahanelerden toplanan sığır ve koyun hidatik kist örneklerinin moleküler karekterizasyonu

Echinococcosis is a life threatening zoonotic infection, recognized as seventeen neglected tropical diseases in the world by WHO, caused by the immature worms of cestodes species of genus Echinococcus and is responsible for significant economic as well as medical losses each year. Different molecular techniques have been used to study the genetic variations of Echinococcus spp, investigations have been made using different nuclear as well as mitochondrial regions for genotyping of the Echioncoccus spp. The purpose of this study is the identification, molecular analysis and genotyping of the Echinococcus spp. in sheep and cattle samples collected from slaughterhouses of Elazig, Turkey by using 446 bp of mitochondrial cytochrome c oxidase subunit 1 (mt-CO1) gene. 90 samples have been selected on the basis of cyst quality and PCR band quality and the samples were then sent for gene sequencing. 5 samples were not sequenced properly so alignment has been performed on 85 samples (19 sheep, 66 cattle) to identify the species of isolates. Out of 85 isolates, 84 were recognized as E. granulosus sensu stricto and one sheep isolate was found to be G6 genotype of E. canadensis which is reported for the first time in Turkey. However single nucleotide polymorphism has been observed in not only samples of different animals but also in samples collected from same cattle. Multiple organ infection has been observed in two of the cattle both in lungs and liver. As a result of haplotype analysis, 16 haplotypes of E. granulosus s.s. have been detected in 66 cattle isolates whereas 8 haplotypes were identified in 19 sheep samples.
