Genotypic characterization of Echinococcus granulosus in Iranian goats
Journal Title: Asian Pacific Journal of Tropical Disease - Year 2013, Vol 3, Issue 5
Abstract
Objective: To isolate and characterize the genotype of Echinococcus granulosus (E. granulosus) from goats in Mazandaran Province, Northern Iran. Methods: A total of 120 goats were screened from abattoirs of Mazandaran Province, Northern Iran. Forty out of 120 samples were infected with cystic echinococcosis and 29 out of 40 infected samples were fertile hydatid cysts (containing protoscolices) which were collected from the livers and lungs of infected goats. DNA samples were extracted from the protoscolices and characterized by mitochondrial DNA sequencing of part of the mitochondrial cytochrome C oxidase subunit 1 gene. Results: Sequences analysis of nine fertile hydatid cysts indicated that all isolated samples were infected with the G1 sheep strain and two sequences were belonged to G1 4 and G1c microvarients of the G1 genotype. Conclusions: The results showed that goats act as alternative intermediate hosts for sheep strain. G1 genotype seems to be the main route of transmission and it should be considered in further studies.
