Scrapie is transmissible spongiform encephalopathy (TSE), which causes neurological signs in sheep, but confirmatory diagnosis is usually made postmortem on examination of the brain for TSE-associated markers like vacuolar changes and disease-associated prion protein (PrP(Sc)). The objective of this study was to evaluate whether testing of brainstem auditory evoked potentials (BAEPs) at two dif...

Classical scrapie is an environmentally transmissible prion disease of sheep and goats. Prions can persist and remain potentially infectious in the environment for many years and thus pose a risk of infecting animals after re-stocking. In vitro studies using serial protein misfolding cyclic amplification (sPMCA) have suggested that objects on a scrapie-affected sheep farm could contribute to di...

1. During development of the sheep, the activities of UDP-glucose-alpha-glucan glucosyltransferase and UDP-glucose pyrophosphorylase and the glycogen content are highest in the liver of lambs 2 weeks old and considerably lower in liver from adult sheep. 2. The activity of hexokinase and the rate of incorporation of [(14)C]-glucose into glycogen are much lower in liver from postnatal sheep than ...

INTRODUCTION Studies about the use of sheep in surgical training and experimental otologic surgery are rare. This study intends to contribute to the knowledge on this field. AIM To study sheep inner ear structures using computerized tomography and serial cross-sections to collect more accurate morphometric data to compare sheep and human ears. MATERIAL AND METHODS This descriptive study com...

Sheep scab caused by the mite Psoroptes ovis (Hering) is a highly contagious disease of sheep. As a first step in developing a mite-derived vaccine for controlling the disease, the soluble antigens in mite extracts which induce an immune response in sheep were identified by electrophoretic and immunoblotting techniques. At least 22 proteins were present in P. ovis extracts as revealed by Coomas...

We present Scalable Host-tree Embeddings for Efficient Partitioning (Sheep), a distributed graph partitioning algorithm capable of handling graphs that far exceed main memory. Sheep produces high quality edge partitions an order of magnitude faster than both state of the art offline (e.g., METIS) and streaming partitioners (e.g., Fennel). Sheep’s partitions are independent of the input graph di...

background : the role of minerals on parasite persistency and the interaction between minerals and animal responses to the parasite infestation is not clear. for these reasons, the present re­search was aimed to compare copper, zinc and iron status in sheep with parasitic myocarditis and healthy ones in 2009. methods : blood and heart tissue samples were collected from 145 slaughtered sheep and...

background:ticks are obligatory blood sucking arthropodsthat can transmit important pathogens. objectives: thedistribution and diversity of ticks fauna were last studied in the northof iran in 2007. mazandaran province has a humid climate, whichis favourable to animal husbandry such as sheep breeding. due tohumid climate, the likelihood of exposure to tick infestation isincreasing. the aim of t...

infectious keratoconjunctivitis (ikc) is a painful, highly contagious ocular disease in sheep and goats. this study was carried out for identification and characterization of causative agent of ocular disease in a sheep flock consisting of 300 ewes in mashhad, iran. several ocular swabs were taken from affected animals. the samples were pooled and processed in a laboratory for isolation of susp...

livestock have made major contribution to human societies by providing food, shelter, fuel, and services.  sheep and goat are economically important livestock play an important socioeconomic role for small and large farmers in libya.  small ruminant animal meat is popular for libyan customers, and demand is particularly high during religious and cultural festivals.  small ruminants is valued fo...
