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 ...

background: the prevalence and intensity of endo and ectoparasites in shrews inhabiting in the dasht-e razan of hamedan province, iran, were determined in this study. methods: by live traps, 64 shrews belong to species bicoloured white-toothed shrews ( crocidura leucodon ) were trapped during 2010-2012. captured animals were euthanized and their gender recorded. the blood thick and thin smears ...

gastrointestinal stromal tumors (gists) are uncommon tumors of the gastrointestinal (gi) tract that occur predominantly in adults. these tumors originated from cajal cells have positive mutations for kit (cd117) or platelet-derived growth factor receptor (pdgfra). gist especially multiple gists are very rare in children and lacking mutations in kit. we present a previously healthy 13 year- old ...

introduction: heterotopic gastrointestinal cyst of the oral cavity is an extremely rare lesion with fewer than 40 cases reported in the english literature. it usually involves the soft tissue covering the floor of the mouth and the tongue. lining of this lesion resembles gastric or intestinal mucosa. case report: in this report we describe the lesion in two boys and discuss their pathogenesis.

Parasitic helminthes remain important causative agents of human, plant and animal diseases. Helminthes seek out food sources and navigate toward potential hosts using olfaction of simple chemical cues in a process called chemoattraction. While several studies have examined how nematodes, including Caenorhabditis elegans, behave in response to a chemoattractant, how the characteristics of the ch...

BACKGROUND Carnivore carcasses on the roads can be regarded as study materials in parasitology and eco-epidemiology. Stray carnivores such as dogs and cats are known to harbor so many different pathogens like zoonotic helminthes. The current investigation, apparent the status of the helminthic parasites found in road killed carnivores from different parts of Guilan Province north of Iran. MET...

Dogs are definite hosts for several zoonotic helminthes and protozoan. Rural areas from the Lobos District in the northeast of Buenos Aires province, Argentina, are mainly used for livestock activity, increasing in this way the number of dogs on farms as well as the human risk of parasitic infections. The aims of this research were to evaluate the endoparasitic infections in dogs from farms in ...

Asthma is common in urban centers in Latin America, but atopic asthma may not be the main phenotype among children. Helminth infections are highly prevalent in poor populations and we hypothesized that they attenuate allergic asthma, while other factors are related to the expression of a non-atopic wheeze/asthma phenotype. A total of 1982 children aged 10.1 (0.76) years (SD) from Southern Brazi...
