in this study, the immunogenicity of three types of antigens (hydatid fluid, protoscolices and whole body of e. granulosus) was investigated in lambs by elisa. sixteen 4–6-month-old lambs of mixed sexes were divided into 4 groups of 4 lambs (three immunized and one control group). twelve lambs as immunized groups received 2 mg of hydatid fluid, protoscolices and whole body of e. granulosus ant...

Cystic echinococcosis is a re-emerging disease in central Asia. A total of 120 soil samples taken from 30 gardens of rural homesteads in southern Kazakhstan were analyzed for the presence of taeniid eggs using a concentration technique. Of these, 21 (17.5%) were shown to be contaminated with taeniid eggs. These isolated taeniid eggs were further analyzed using a polymerase chain reaction specif...

Hydatid disease (echinococcosis) has a two-host cycle involving the domestic dog and grazing animals. Humans are also infected by the dog. Both unilocular (Echinococcus granulosus in yaks, sheep, and goats) and multilocular (alveolar) (E. multilocularis in hares and rodents) hydatids are common in western Sichuan in the People's Republic of China. Humans and dogs are equally infected with both ...

The cases of nine Polish patients with diagnosed cystic echinococcosis (CE) were examined. A total of nine isolates obtained postoperatively were investigated using PCR and sequencing. The mitochondrial region of nad1 gene was amplified. This PCR and sequencing analysis revealed the presence of Echinococcus canadensis G7 in seven patients and E. granulosus G1 in two patients. These data demonst...

Human hydatid disease (cystic echinococcosis, CE) is a chronic parasitic infection caused by the larval stage of the cestode Echinococcus granulosus. As the disease mainly affects the liver, approximately 70% of all identified CE cases are detected in this organ. Optical molecular imaging (OMI), a noninvasive imaging technique, has never been used in vivo with the specific molecular markers of ...

Echinococcus multilocularis (EM) is caused by the larval stage of the tapeworm. The main endemic regions for human alveolar echinococcosis are Central Europe, Russia, Turkey, Japan, China, Eastern France, North America. EM is an endemic disease in Turkey and especially common in the eastern Anatolia Region as seen in our case. The liver is the primary focus of the disease, cerebral localization...

Over the last decade, studies have begun to shed light on the distribution and genetic characterization of Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), in North America. Recent findings indicate that the parasite is likely expanding its range in the central region of the United States and Canada and that invasions of European strains might have occurred. In ...

The aim of this study was to obtain uniformity in strobilar development of Echinococcus multilocularis from protoscoleces in vitro. The isolate of E. multilocularis used was derived initially from a human case in France and subsequently maintained in the laboratory by intraperitoneal passage in Meriones unguiculatus. Protoscoleces used for culture were obtained using preparative procedures in w...

BACKGROUND One of the most important zoonotic helminths in the world is known as Echinococcus granulosus. Different strains of the E. granulosus have been described based on morphological and molecular characterizations, however, there is limited information regarding the characteristics of the phenotypes and genotypes of E. granulosus in Iran. METHODS The present study was prepared to evalua...

OBJECTIVE Echinococcus granulosus is a globally important cestode parasite causing remarkable medical and economical losses in the world. Ten genotypes (G1-G10) have been identified within this complex species. Protoscoleces rostellar hook characters e.g. total large and small hook lengths may be useful to differentiate genotypes. This study investigates the value of rostellar hook morphometry ...
