Molecular Identification of Echinococcus granulosus in Tunisia: First Record of the Buffalo Strain (G3) in Human and Bovine in the Country
نویسندگان
چکیده
It has been demonstrated that human hydatidosis was generally due to G1 genotype of Echinococcus granulosus throughout the world. Nevertheless, some other genotypes, such as G3, were recently identified for human cyst. The present work confirms the predominance of the sheep strain G1 in humans, bovine and ovine and demonstrates for the first time the occurrence of the buffalo strain G3 in human and bovine in Tunisia.

Molecular characterization of a new microvariant of the G3 genotype for Echinococcus granulosus in water buffalo in Iran
In this study, molecular characterization of Echinococcus granulosus sample obtained from water buffalo originating from southwest of Iran was performed using comparative sequence analysis of cox1 mitochondrial gene. DNA was extracted from protoscoleces removed from hydatid cyst from the liver of a 2-year-old male buffalo slaughtered in Khuzestan province. Molecular and phylog...

BACKGROUND Cystic echinococcosis (CE) caused by the Echinococcus granulosus, is a major public health problem worldwide, including India. The different genotypes of E. granulosus responsible for human hydatidosis have been reported from endemic areas throughout the world. However, the genetic characterization of E. granulosus infecting the human population in India is lacking. The aim of study ...

Background and purpose: India and Iran are an important endemic focus of cystic hydatid disease (CHD), where several species of intermediate host are commonly infected with Echinococcus granulosus. Strain characterization of E. granulosus is significant for the development of an effective control programme and to asses the infectivity. In present study, genetic variations in tapeworms causing...

In view of the medical, veterinary and economic importance of hydatid disease in India, our study aimed to determine the prevalence and genotypes of Echinococcus present in domestic livestock in India. Out of 21,861 animals examined, cattle were found with the highest prevalence of hydatid cysts (5.10%) followed by buffaloes (3.81%), pigs (0.87%) and sheep (0.075%). Phylogenetic analysis of the...
متن کاملIs the Goat a New Host for the G3 Indian Buffalo Strain of Echinococcus granulosus?
Four goats bred in Central Italy (province of Rieti) revealed, in the liver, metacestodes of Echinococcus granulosus. The cysts, unilocular and fertile, were examined by microscopy and molecular diagnostics. Morphological data on the rostellar hooks are in agreement with the original description of the strain found in buffaloes and are largely compatible with those reported in Europe for cattle...
