Isolation of Parasites

چکیده
Fasciola hepatica, a liver fluke, is a causative agent of fascioliasis in mammals (sheep, cattle, goat, ox and other ruminants, pig, hare rabbit, beaver, elephant, dog, cat and kangaroo). In the unusual hosts, such as man and the horse, the fluke may be found in the lungs, under skin or other situations. The parasite Fasciola hepatica is a hermaphroditic trematode, which is particularly common in sheep and cattle. Transmission of F. hepatica is dependent on the presence of its lymnae snail intermediate hosts. Following ingestion of metacercaria by the hosts, the juvenile worms burrow through the host gut walls and migrate to the liver, where they cause extensive damage before moving into the bile ducts. Finally, the parasites pass through the bile duct walls and develop into mature forms that live in the microenvironment of the bile ducts. This worm causes important economic losses due mainly to liver damage and reduced production of meat and milk [11, 13, 14].

Presence of Immunoglobulins on the Surface of Lesion-Derived Amastigotes of Leishmania major As a Tool for Isolation of Amastigote Stage from BALB/c Mice
The onset of infections by Leishmania parasites mainly caused by amastigote growth inside the macrophages. One of the important properties of lesion-derived amastigote is thought to be the attachment of various host proteins including immunoglobulins on the surface of amastigote. In this study, the presence of immunoglobulins on the surface of lesion-derived amastigotes was detected by Western ...
متن کاملParasites contribute to ecologically dependent postmating isolation in the adaptive radiation of three-spined stickleback
Spatial variation in parasitic infections is common, and has the potential to drive population divergence and the reproductive isolation of hosts. However, despite support from theory and model laboratory systems, little strong evidence has been forthcoming from the wild. Here, we show that parasites are likely to cause reproductive isolation in the adaptive radiation of three-spined sticklebac...

Background and purpose: Study of intestinal parasites in the rodents has medical, hygienic, veternary and biologically importance. Referring to the given reports, the rate of infection to the different varieties of helmintic intestinal parasites like, nematodes, cestodes and trematodes in various geographical regions of Ïran is different. Hence in order to determine all types of helmintic int...
متن کاملResearch Article: Morphometric study and identification of external parasites in Hypophthalmichthys molitrix breeders in Guilan, Iran
The parasites that normally cause fish disease under farming condition possess a direct life cycle with no need to intermediate hosts for dissemination. The ensuing infection can therefore spread rapidly inducing more damaging lesions in the external parts of host especially the gills. In this study, in order to isolate and identify foreign parasites of phytophagous fish in Guilan province, 4 f...
متن کاملTechniques for Isolation and Evaluation of Fungal Parasites of Heterodera glycines.
A facultative fungal parasite, Arkansas Fungus 18 (ARF18), was isolated from at least 10 different sources of Heterodera glycines in different areas in the United States. Techniques used for isolation and in vitro evaluation of fungal parasites of H. glycines were described. Successful isolation of probable egg parasites depends on isolation from individual eggs. Selective isolation and a simpl...
