In 3 out of 4 attempts strains of a Theileria sp. of low virulence were isolated in the laboratory by feeding adult Rhipicephalus appendiculatus collected from the field on susceptible cattle. One of the strains, previously identified as Theileria? taurotragi (Tzaneen), was found to be serologically cross reactive with the other 2 strains. It was concluded that T.? taurotragi is prevalent in So...

The genome of the sheep scab mite, Psoroptes ovis, was analysed for presence neuropeptide and neurohormone precursors their G protein-coupled receptors (GPCRs). Many these showed significant similarities to those known or predicted from other Acaridae also insect species. Similarities orthologous Ovis aries, host P. were evaluated. roles neuropeptides neurohormones in control behavioural physio...

Based on mitochondrial DNA (mtDNA) cytochrome b (cyt b) gene was partially sequenced and analysed in order to investigate genetic diversity between domestic sheep (Ovis aries) synthetic line BCP n=16 and wild sheep mouflon (Ovis musimon) n=24 from the Sowie Mountains in Poland. All 18 haplotypes were observed which formed two distinct clades in O. aries BCP synthetic line and three clades in mo...

The origins of domesticated sheep (Ovis sp.) in China remain unknown. Previous workers have speculated that sheep may have been present in China up to 7000 years ago, however many claims are based on associations with archaeological material rather than independent dates on sheep material. Here we present 7 radiocarbon dates on sheep bone from Inner Mongolia, Ningxia and Shaanxi provinces. DNA ...

The prevalence of Anaplasma infection was studied in cattle, sheep, and goats in the Mashhad area from 1999 to 2002. A total of 160 cattle from 32 farms and 391 sheep and 385 goats from 77 flocks were clinically examined for the presence of Anaplasma spp. in blood smears. The study revealed that 19.37% of cattle were infected with Anaplasma marginale and 80.3% of sheep and 38.92% of goats were ...

Theileria annulata, a protozoan parasite of cattle and domestic buffaloes, is transmitted by ticks of the genus Hyalomma, and causes a disease named Mediterranean or tropical theileriosis. In this research 50 cattle naturally infected with Theileria annulata were treated with the extract of the plant Peganum harmala. The treatment was continued for 5 days, the dose of the extract being 5 mg/kg ...

background: rhipicephalus sanguineus and hyalomma marginatum are the most common spe­cies in sheep herds in northeast of iran. there is preliminary evidence that these species may be the vectors of babesia ovis in iran. we carried out two experiments in mashhad area, khorasan razavi province to determine whether b. ovis could be transovarially transmitted by r. san­guineus and h. marginatum . m...

Babesia ovis plays an important role in causing anemia and kidney dysfunction in affected animals. There are few extensive studies about hematological and biochemical findings of small ruminants' babesiosis caused by B. ovis. The aim of this study was to evaluate the effect of babesiosis on some hematological and biochemical parameters in infected small ruminants with B. ovis. A total of 280 sh...

To develop an ELISA technique for the detection of antibodies against Babesia ovis, the infectederythrocytes were lysed and the supernatant soluble antigen, after sonication and ultracentrifugation of thelysate was used as antigen. Optimal dilution of the antigen was determined by checkerboard titrations, usingpositive and negative control sera. A correlation of 85% was observed between the res...
