Echinococcosis is one of the most important dog related zoonotic disease of animals and human (Soulsby, 1982). Infection with the larval forms of Echinococcus granulosus are responsible for considerable economic losses to meat industry because of liver damage in food animals. Whereas adult tapeworms in the gut of infected dog may produce clinical signs. The prevalence of E. granulosus in stray ...

abstract hydatid disease is caused by echinococcus spp. especially echinococcus granulosus that is the most common cause of hydatid disease in humans. this disease occurs either through direct contact with infected dogs or indirectly from the ingestion of contaminated water or food with eggs of worms. the most common site in human is the liver (59-75%), followed in frequency by lung (27%), kidn...

OBJECTIVE This study was to clone, identify and analyze the characteristics of egG1Y162 gene from Echinococcus granulosus. METHODS Genomic DNA and total RNAs were extracted from four different developmental stages of protoscolex, germinal layer, adult and egg of Echinococcus granulosus, respectively. Fluorescent quantitative PCR was used for analyzing the expression of egG1Y162 gene. Prokaryo...

BACKGROUND Cystic echinococcosis (CE) is caused by the larva of tapeworm Echinococcus granulosus. Dogs and other canids are the primary definitive hosts for this parasite. CE may develop after accidental ingestion of tapeworm eggs, excreted with the feces of these animals. In the intestine, the larvae released from the eggs are nested in the liver, lungs or other organs of livestock as intermed...

40 Echinococcus isolates from sheep and cattle in Southern Brazil were genetically analysed in order to obtain further data on the presence of different taxa of the Echinococcus granulosus complex. Differentiation was done using a PCR technique and sequencing of mitochondrial cytochrome c oxidase subunit 1 (CO1). Most samples (38) could be allocated to the sheep strain (G1) of E. granulosus, wh...

This investigation aimed to evaluate the differential expression of HoxB7 and notch genes in different developmental stages of Echinococcus granulosus sensu stricto. The expression of HoxB7 gene was observed at all developmental stages. Nevertheless, significant fold differences in the expression level was documented in the juvenile worm with 3 or more proglottids, the germinal layer from infec...

Hydatid cyst commonly occurs in liver, followed by lungs. It may occur in other organs also. But isolated retroperitoneal hydatid cyst occurring in right iliac fossa is rare. A 25 years old male presented with a slowly growing mass in right iliac fossa for two years. He had dull aching pain in right iliac fossa, early satiety and occasional history of pain during micturation. No history of ches...

An update on our understanding of molecular variation in Echinococcus and Taenia is provided. Genetic variation within certain species of Echinococcus is now a well accepted phenomenon and a number of intraspecific variants or strains of E. granulosus, in particular, have been characterized hitherto using a range of procedures. Newly acquired molecular information has now been used in epidemiol...

Cystic echinococcosis (CE) is an important worldwide zoonotic disease that causes large economic losses and human suffering. Echinococcus granulosus, the causative agent of CE, exhibits different genotypes in different locations. In order to identify its genotypes and analyze its genetic structure on the Tibetan Plateau, we collected 72 hydatid cysts from different intermediate hosts and amplif...

Echinococcus granulosus is widespread in Australian wildlife where its reproductive potential may be greater than in domestic animals. The parasite is zoonotic; humans may develop hydatid cysts following ingestion of eggs. Infected definitive hosts, dingoes, their hybrids and foxes may pose a public health risk but even heavy parasites loads are of no significance to the animals’ health. The pa...
