It has been reported that monoclonal antibodies (MAbs) to the E1E2 glycoproteins may have the potential to prevent hepatitis C virus (HCV) infection. The protective epitopes targeted by these MAbs have been mapped to the regions encompassing amino acids 313-327 and 432-443. In this study, we synthesized these two peptides and tested the reactivity of serum samples from 336 patients, 210 of whic...

OBJECTIVE To determine prevalence of anthelmintic resistance in cyathostome nematodes of horses in the southern United States. DESIGN Cross-sectional study. ANIMALS 786 horses on 44 farms and stables in Georgia, South Carolina, Florida, Kentucky, and Louisiana. PROCEDURE Fecal egg count (FEC) reduction tests were performed on 44 large farms and stables.

OBJECTIVE Determining Leptospira spp . antibody seroprevalence in an apparently healthy population and in groups at risk plus their associated factors in the town of Villavicencio in the Meta department of Colombia MATERIALS AND METHODS A cross-sectional epidemiological model was used (subjects being selected by convenience sampling). Blood-samples were obtained by cubital puncture from (n: 5...

BACKGROUND The aim of this study was to evaluate the content of mercury (Hg), arsenic (As), nickel (Ni) and tin (Sn) in raw cow's milk of traditional and industrial sites from 8 different sites in Arak City, Markazi Province, Iran. METHODS In this cross sectional study, a total of 32 samples were collected from sub-cities of Arak, Iran via subjective sampling method. Both industrial and tradi...

A cross-sectional survey was performed to estimate the prevalences of antibodies to Toxoplasma gondii (ELISA, IFAT), Sarcocystis spp. (ELISA, using S. miescheriana as antigen) and Neospora caninum (ELISA, immunoblotting) in sows from breeding farms in southern Hesse, Germany. A total of 2041 plasma samples of sows from 94 randomly selected farms was examined. Data on farm profiles, husbandry ma...

The aim of this study was to determine the seroprevalence of avian influenzaH9N2 subtype in the industrial ostrich farms and its geographical distribution. This cross-sectional study was conducted from January to June 2015. A total of 40 farms were selected from different provinces of Iran, from each of which 11 ostriches (n=440) were sampled. The sera samples were examined using 4 hemagglutina...
