Zoonotic ectopic fascioliasis: review and discussion

ABSTRACT

Ectopic fascioliasis [EF] has direct and indirect effects on both humans and animals. The phenomenon of EF was individual cases in the period from 1950 up to the end of last century. From the period of 2000 up .to 2006, plenty of researches were on EF in the developed and undeveloped countries. Nineteen EF cases infected with the immature and few with the mature worms were 13 females and 6 males. Three cases of lymphatic, pleural and breast fascioliasis reached the adults and laid their eggs in a lymph node in the cervical region pleural cavity and breast tissues. Until recent, knowledge about the ectopic fascioliasis pathway is little. Fasciola hepatica was the commonest species in most cases. The effect of fascioliasis might be direct to liver as ectopic foci or indirect on other organs due to the metabolites and secretory excretory products. All ages and both sexes were EF infected. Watercress topped the list of water plants born encysted metacercariae followed by lettuce, mint, and alfalfa. Nearly 24 million Egyptians at risk and about 800.000 were infected. On the global scale, about 180 million are at risk of infection
