Zoonosis Update T he term ehrlichiosis has been broadly applied to a variety of diseases of humans and animals caused by pathogens formerly classified in the genus Ehrlichia. However, a recently proposed taxonomic reorganization 1 has recommended the reclassifications of some former Ehrlichia species under the genera Anaplasma and Neorickettsia and Cowdria ruminantium under the genus Ehrlichia....

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 ...

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...

Serological methods were utilized to detect Anaplasma and Ehrlichia infection in domestic animals in Xinjiang Uygur Autonomous Region, China. By using an indirect immunofluorescence assay (IFA), antibodies that reacted with Anaplasmaphagocytophilum and Ehrlichiachaffeensis were detected mainly in ruminants kept on pastureland in Altai, Ili and Kashgar area. Antibody titers up to 1:320 were reco...

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...

That lurks inside white-footed mice and white-tailed deer. Ferried by blood-thirsty ticks in the sticks, This Anaplasma soul is passed on to its bodily incarnations— Larva to nymph to tick. A new generation of infected vampires is born. Our love for the outdoors encroaches on tick territory. A tick bite injects Anaplasma storming defender neutrophils, Using MSP2 hooks to scale the walls. Zombie...

A total of 27 ticks, comprising Rhipicephalus sanguineus (Latreille) (n = 21), Haemaphysalis leachi (Andouin) (n = 4) and Haemaphysalis paraleachi (Camicas, Hoogstraal & El Kammah) (n = 2) were recovered from two clinically healthy female dogs in the Democratic Republic of the Congo. DNA of Anaplasma platys was detected in a female R. sanguineus, using primers derived from the 16S rRNA gene, wh...

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...
