Abstract Stachytarpheta jamaicensis L. Vahl has traditionally been used as an anti-trematode, but its effectiveness needs to be scientifically tested. This study aimed determine the anti-trematode activity of leaf extract in vitro. The leaves were extracted using water, and their secondary metabolites characterized by phytochemical screening. Paramphistomum sp isolated from rumen was identified...

the present study was carried out to determine parasitic infection of sheep with gastrointestinal helminthes in a slaughterhouse in fereidoonkenar city, iran. a total number of 50 sheep were examined from april to september 2008. nematodes were removed from abomasums, small and large intestines, and kept in a.f.a. solution (alcohol, formaldeyde, acetic acid, distilled water, and glycerine) for ...

Parasite life-history traits should reflect past environmental and host-related selective pressures acting to produce strategies that maximize transmission success. The evolution of adult body size and egg production in 804 species of trematode parasites was investigated using independent contrasts derived from a phylogeny of trematodes. Contrasts in trematode body size were positively correlat...

Parasites are integral members of natural communities, but large-scale determinants of their abundance and diversity, including the importance of biotic and abiotic factors, both natural and anthropogenic, are often not well understood. Here, we examine which factors best predict larval trematode communities in the mudsnail host Ilyanassa obsoleta across a regional landscape. At 15 salt marsh s...

rats are capable to harbor various pathogens, among which certain species of zo-onotic parasites are included. a long-term detection of parasite fauna of rats has sporadically been carried out in iran. abundance of these vertebrate pests is of great importance as regards public health issue. the present paper is focused on a digenean trematode plagiorchis muris, obtained during a comprehensive ...

An extinction necessarily affects community members that have obligate relationships with the extinct species. Indirect or cascading effects can lead to even broader changes at the community or ecosystem level. However, it is not clear whether generalist parasites should be affected by the extinction of one of their hosts. We tested the prediction that loss of a host species could affect the st...

The study of the functional morphology reproductive system trematodes, as well its individual parts, provides an opportunity to solve important problem that plays a huge role in theoretical and practical terms directed regulation fecundity endoparasites. article is devoted vitelline glands Mehlis process formation resistant egg shells on example Parastrigea robusta trematode. mechanisms are rev...
