The subject of this study was to compare the seropre valence of Border Disease Virus (BDV) infection using an indirect Enzyme-linked immune sorbent assay (ELISA) test among imported and native sheep herds. The present study was carried out between January and June 2012. Totally، 182 serum samples was tested. Antibodies against BDV were detected using an indirect ELISA test. Data were analyzed u...

The aim of the present study is to determine the characteristics of genotype and phenotype of Echinococcus granulosus derived from wild sheep and to compare them with the strains of E. granulosus sensu stricto (sheep-dog) and E. granulosus camel strain (camel-dog) in Iran. In Khojir National Park, near Tehran, Iran, a fertile hydatid cyst was recently found in the liver of a dead wild sheep (Ov...

background: the acute phase response is beneficial to theanimal in restoring homeostasis, and measuring the circulatingacute phase proteins, cytokines, and enzymes can be used toevaluate the innate immune system's responses to invader agentssuch as bacterial lipopolysaccharide. measurement of theseparameters has shown to be useful as diagnostic and prognosticmarkers in animal endotoxemia. objec...

Blood samples were collected from the jugular vein of 101 clinically healthy Iranian fat-tailed sheep according to their age (5 years) and sex. Serum haptoglobin (Hp) was measured based upon the preservation of the peroxidase activity of haemoglobin, which is directly proportional to the amount of Hp. The reference value for serum Hp of apparently healthy Iranian fat-tailed sheep was 0.05-0.18 ...

Mitochondrial DNA (mtDNA) has been used extensively to study population genetics because it has the unique features of maternal inheritance, a relatively fast rate of evolution and lack of recombination. A total of 82 unrelated sheep from 10 Iranian indigenous sheep breeds were investigated to determinate the maternal genetic diversity using a sequence of a 685 bp segment of the displacement lo...

The major histocompatibility complex (MHC) plays a central role in the control of disease resistance and immune response. Extensive genetic diversity in MHC genes provides a valuable source for genetic improvement, via selection, in many domestic animals. Exon 2 of the class II MHC, termed Ovar-DRB1 in domestic sheep (Ovis aries), has been suggested as important disease resistance and immune re...

BACKGROUND The purposes of the present study were morphometric characterization of rostellar hooks of Taenia multiceps and to investigate the association of hook length variation and the variability within two mitochondrial genes of sheep isolates of the parasite. METHODS Up to 4500 sheep brains were examined for the presence of C. cerebralis. Biometric characters based on the larval rostella...
