چکیده

background: echinococcus granulosus , a zoonotic cestode parasite, causative agent of hydatid cyst is endemic in many parts of the world including the middle east. study on different aspects of this parasite is very important and valuable. however, working with adult worms which their habitat situated in the small intestine of canids, is dangerous and risky. achieving such risky situa­tion needs a controlled condition which is cultivation of the organisms in the laboratory. in this regard, cultivation of e. granulosus protoscoleces leading to adult worms was established in the laboratory for the first time in iran. methods: under aseptic conditions a number of protoscoleces were cultivated in diphasic s.10e.h medium using co2 incubator to produce adult worms. results: different forms of parasites including pre-segmentation stages (ps1 - ps4) and segmenta­tion stages (s5-s8) and developing stages in segmented worms (s10-s11) were ob­served and evaluated in these medium. finally adult worms contained four proglottids with a large and distinct genital pore were observed 50-55 days post cultivation. these parasites do not produce fertile eggs and conclusively do not have risk of hydatid disease transmission to the research­ers. conclusion: the mentioned method for producing e. granulosus adult worms can open a new window for researches and facilitate working on different aspects of hydatidosis especially for diagnosis, protection and treatment studies.

BALB/c Mice Immunity to Hydatidosis Induced by In-vitro Reared Echinococcus granulosus Adult Worm Antigens

Background: Echinococcosis is a zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. Several native and recombinant antigens, derived from different stages of E. granulosus life cycle, have been used for vaccine trials. In vitro reared adult worms are good candidates for vaccination as they do not produce fertile egg/s and do not have any risk of contamination for r...

Immune Responses to Antigens of in vitro Reared Echinococcus granulosus Adult Worms in Balb/c Mice

Background: Cystic echinococcosis (CE), also known as echinococcosis/hydatidosis, is one of the most important parasitic diseases in the world. It enhances both humoral and cellular (Th1 and Th2) responses in infected host. Different antigens of the worm may favor the Th1 or Th2 immune responses in CE patients. Objective: To evaluate the humoral and cellular immune responses of Balb/c mice agai...

In vitro effects of nitazoxanide on Echinococcus granulosus protoscoleces and metacestodes.

OBJECTIVES Infection of humans and domestic ruminants with the larval stage (metacestode) of Echinococcus granulosus results in cystic echinococcosis (CE). The metacestode causes a space-occupying lesion in visceral organs, most commonly in the liver. Benzimidazole carbamate derivatives, such as mebendazole and albendazole, are currently used for chemotherapeutic treatment of CE. In human patie...
