Determining quality of food ingested and digestibility can be helpful in understanding the mechanisms that determine trophic plasticity, which is the ability of a given species to use a more advantageous food source at a given time. In this study, the chemical composition and digestibility of food ingested by various trophic fish groups at different sites of the Upper River Paraná floodplain ar...

Echinococcosis is cosmopolitan zoonosis caused by adult or larval stages of tapeworrns belonging to the genus Echinococcus Rudolphi, 1 80 1 . Within the genus Echinococcus four species are presently recog­ nised, namely Echinococcus granulosus, E. multiloc­ ularis, E. oligarthrus and E. vogeli, and taxonomic revision of the genus is probably needed (Thompson RCA, McManus DC, 2002, Trends Parasi...

background: echinocuccus granulosus, the causative agent of cystic echinococcosis has long been recognized as having a high degree of genetic divergence. the strains characterization seems to be essential for the establishment of a preventive and control strategy in every endemic area. using dna based methods for strain /genotype characterizations of e. granulosus have some difficulties, especi...

background: hydatid cyst disease (hcd) or echinococcosis has a worldwide distribution and is endemic in many countries of mediterranean region. in iran, due to various climatic conditions, the rate of the disease is diverse in different parts. the most infected regions are the domains of alborz and zagros mountains where there is a high rate of ruminants and the main carrier of people are anima...

case presentation here, we report three rare but well-documented cases of central nervous system hydatid cysts that occurred in patients in iran. conclusions we also provide a brief review of the literature examining similar occurrences. this article intends to provide thorough information about the disease for readers. introduction hydatid disease is caused most common by echinococcus granulos...

this study has been conducted in the slaughter- house of the city of kerman, for one year, starting march 1993. a total number of 16402 livestocks including 5013 sheep, 8163 goats and 3226 cattle were examined in a regular manner, 120 days, with a mean of 30 days per season. after recording the king, sex and origin of each animal, liver and lungs were examined carefully for hydatid cyst. in gen...

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...

BACKGROUND Cystic echinococcosis (CE), a zoonotic parasitic infection caused by the metacestode (larvae) stage of dog tapeworm Echinococcus granulosus and recognized as a major economic and public health concern in the world. This study aimed to investigate the in vitro scolicidal effect of methanolic extract of Berberis vulgaris L. roots and its main compound, berberine against protoscoleces o...

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 ...
