The diversity of populations in domestic species offers great opportunities to study genome response to selection. The recently published Sheep HapMap dataset is a great example of characterization of the world wide genetic diversity in sheep. In this study, we re-analyzed the Sheep HapMap dataset to identify selection signatures in worldwide sheep populations. Compared to previous analyses, we...

Previous studies based upon competition between different organic anions for biliary excretion in vivo have suggested that all organic anions share a common hepatic secretory mechanism. Corriedale sheep with an inherited defect in organic anion excretion by the liver were used to study this problem directly without the need for competition studies, the results of which are difficult to analyze....

ONCEL, T., G. VURAL: Occurrence of Toxoplasma gondii antibodies in sheep in Istanbul, Turkey. Vet. arhiv 76, 547-553, 2006. ABSTRACT This study was carried out in order to determine the occurrence of Toxoplasma gondii antibodies in sheep in five districts of Istanbul, Turkey. A total of 181 sera taken from sheep were examined for antibodies to Toxoplasma gondii using an enzyme-linked immunosorb...

Sheep betaretroviruses represent a fascinating model to study the complex evolutionary interplay between host and pathogen in natural settings. In infected sheep, the exogenous and pathogenic Jaagsiekte sheep retrovirus (JSRV) coexists with a variety of highly related endogenous JSRVs, referred to as enJSRVs. During evolution, some of them were co-opted by the host as they fulfilled important b...

The aim of the investigation was to off-line compare parameters of uterine EMG signals recorded during pregnancy in humans and sheep. Uterine corpus EMG recording sessions were performed in humans and in sheep. Sixty-five women underwent uterine corpus EMG recording sessions using abdominal surface skin electrodes. Six sheep underwent multiple EMG recording sessions using implanted electrodes. ...

In 1995 several outbreaks of food poisoning in humans occurred in Iceland, that were traced to salmonella contamination of singed sheep heads. This prompted us to study the prevalence of salmonella infection in sheep and to trace where and how infection might have occurred. Faecal, intestinal contents and tonsillar samples were collected in the spring and autumn from sheep on 50 farms in the so...

This study aimed to determine the prevalence and risk factors for C. tenuicollis among goats and sheep in slaughterhouses in Paraíba. 390 animals (195 goats and 195 sheep) in the municipalities of Patos and Esperança, Paraíba, Brazil, were inspected between February and May 2014. The prevalence of C. tenuicollis was 39% (76/195) in goats and 17.4% (34/195) in sheep. In both species, most of the...

Anti-sheep erythrocyte antiserum suppressed the in vitro immune response of swine spleen cells to sheep erythrocytes. Inhibition of the in vitro anti-sheep erythrocyte response was also observed in neonatal spleen cells, which were obtained from piglets recently fed colostrum. Addition of purified protein derivative (PPD) to spleen cell cultures prepared from animals previously sensitized to My...

The present study was conducted for isolation, identification and characterization of Clostridium perfringens organism from lamb dysentery in Dinajpur district of Bangladesh. Affected sheep showed clinical signs as dysentery, diarrhea, anorexia, weakness, and dehydration. A total of 20 faeces and rectal swab were collected from different sheep farms of different area of Dinajpur District of Ban...

In this study, C. perfringens strains isolated from healthy and diseased sheep were analysed by multiplex PCR in order to to detect the presence of the alpha, beta, epsilon, iota and enterotoxin genes. C. perfringens was isolated from 52 of 104 sheep with enterotoxemia signs and from 61 of 194 clinically healthy sheep. Genotyping of 52 strains from diseased sheep indicated that 33 (64%) were ty...
