BACKGROUND Cystic Echinococcosis(CE), caused by infection with the larval stage of the cestode Echinococcus granulosus (E. granulosus), is a chronic parasitic zoonosis, with highly susceptible infection in sheep. However, the comprehensive molecular mechanisms that underlie the process of E. granulosus infection in the early stage remain largely unknown. The objective of this present study was ...

elevated amount of the free radicals due to ionizing radiation causes deteriorating damage on immune system. therefore, we made attempts to investigate the protective effect of vitamin e (vit-e), a biological antioxidant in balb/c mice, so as to find an affordable prophylactic supplementation for individuals who are at risk. several groups of mice were selected and exposed to sub-lethal g -irra...

A survey of coccidia in the Rocky Mountain bighorn sheep (Ovis. c. canademis) in Alberta and Kootenay NationaI Park, British Columbia, was conducted from the winter of 1967 to the spring of 1969. Ninety percent of 530 fecal samples cxaniined were positive for coccidia. The species recovered, in order of prevalence, were Eimeria ovina ( syn., E. arloingi) (S6%), E. parva (3579, E. crandallis (34...

Enterohemorrhagic Escherichia coli (EHEC) of the O157:H7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human EHEC disease. The aim of the present study was to investigate the prevalence of E. coli O157: H7/NM in raw meat samples from two provinces of Iran. During a period from March 2010 to March 2011. Two hundred and ninety five raw meat samples were...

An epidemiological and molecular survey on the occurrence of Echinococcus hydatid cysts in livestock was conducted in Greece. In total 898 sheep, 483 goats, 38 buffaloes, 273 wild boars and 15 deer were examined and 30.2% (6.45% cyst fertility), 7.86% (3.2% cyst fertility), 42% (7.9% cyst fertility), 1.1% (0% cyst fertility), 0% of them were found infected, respectively. Infection rate in diffe...

This study aimed to characterize the role of phosphorylation of caseins in selective allergy to goat milk (GM) and sheep milk (SM) in patients with good tolerance to cow milk (CM). We performed skin prick tests with milk and caseins from CM, GM, and SM and immunoblotting and specific immunoglobulin (Ig) E determinations with milk and casein from cow and GM and SM. Sensitization to milk and case...

The objectives of this study were to determine the influence of application site and sheep breed on the efficacy of a flumethrin (1% m/v) solution for the control of 'bont'-legged (Hyalomma spp.) and red-legged ticks (Rhipicephalus evertsi evertsi). This study was conducted from November 1996 to February 1997 on 3 farms in the southwestern Free State Province. Two trials were conducted on Dorpe...

Blood sera samples from 99 clinically healthy goats, 230 sheep and 171 rams were investigated by CF test and indirect ELISA. In case of goats, 3.03% seroprevalence was detected, in sheep it was 3.04%, whereas, in case of rams seroprevalence was 0% by using complement fixation test. Using iELISA in the same groups the seroprevalences observed were, 24.24% in goats, 11.30% in sheep and 5.30% in r...

Ovine interferon-gamma (IFN-γ) cDNA was isolated from total mRNA of peripheral blood mononuclear cells from indigenous sheep by reverse transcription PCR. The cDNA was successfully cloned, sequenced and expressed in Escherichia coli as thioredoxin fusion protein. Sequence comparison of Indian sheep IFN-γ showed high nucleotide homology with published IFN-γ sequences of sheep and other species o...
