Epizootiological monitoring studies on parasitoses of domestic ruminants indicate that one the most common causes nematodes digestive tract in large and small cattle are helminths genus Trichuris. Those develop directly – without intermediate hosts, their embryonic stages became invasive environment under favorable conditions. The eggs those parasites incredibly resistant can be infective for a...

During ongoing surveys of parasites of wild animals in the Kruger National Park, a total of 96 kudu. Tragelaphus strepsiceros, were culled in the southern part of the park at monthly intervals from April 1981 to March 1983. A single kudu was shot in the same area in November 1983. Two more kudu were obtained from Pafuri in the northern part of the Park during October 1981 and another from near ...

Geohelminths parasitizing sheep are widespread throughout the world and have a significant pathogenic effect on animal body. Among them, one of leading places in terms distribution is occupied by helminths genus Trichuris. This due to high resistance trichurises effects chemicals adverse environmental factors. The presence viable eggs trichurosis pathogens surface layer soil sufficiently long p...

Abstract The introduction of non-indigenous organisms in new areas the context host-parasite interactions is still poorly understood. This study aimed at a parasitological and histopathological comparison two phylogenetically distinct forms freshwater snail Theodoxus fluviatilis River Rhine system: native Northern-European form, which showed decline for unknown reasons nowadays extinct Rhine, D...

This investigation was undertaken to verify the prevalence of helminths parasites in the gastrointestinal tract of catfish. A total number of 116 catfish (Silurus glanis) were collected from Zarrine-roud river and examined for helminths. Fish were examined after washing contents of gastrointestinal tract and observed for the presence of helminths using a stereo microscope and a light microscope...
