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...

in order to study the seroprevalence of pestivirus infection in small ruminants of ahvaz at khouzestan province of iran, 148 sheep sera and 143 goat sera were randomly collected and tested by seroneutralization. seroneutralization was performed by nadl strain of bovine viral diarrhea virus genotype 1. the results indicated the overall seroprevanelces of 46.62% in sheep and 32.871% in goats. pre...

Paratuberculosis as well as the slow virus infections maedi/visna and jaagsiekte came to Iceland in 1933 when 20 sheep of the Karakul breed were imported from Halle, Germany. At least five of these sheep were subclinical carriers of paratuberculosis. Within 16 years paratuberculosis together with the other Karakul diseases (maedi/visna and jaagsiekte) almost ruined sheep farming, the main agric...

We investigated commercially available dermal sheep collagen either cross-linked with hexamethylenediisocyanate, or cross-linked with glutaraldehyde. In previous in vitro studies we could discriminate primary, i.e. extractable, and secondary cytotoxicity, due to cell-biomaterial interactions, i.e. enzymatic actions. To develop dermal sheep collagen for clinical applications, we focused in this ...

BACKGROUND Animal models should display important characteristics of the human disease. Sheep have been considered particularly useful to study allergic airway responses to common natural antigens causing human asthma. A rationale of this study was to establish a model of ovine precision-cut lung slices (PCLS) for the in vitro measurement of airway responses in newborn and adult animals. We hyp...
