Feeding-associated gene expression in sheep scab mites (Psoroptes ovis)

The mite Psoroptes ovis is the causative agent of sheep scab. Although not usually fatal, the disease can spread rapidly and is a serious animal welfare concern. Vaccine development against ectoparasites has primarily focussed on two sources of candidate vaccine antigens - "exposed" antigens that are secreted in saliva during feeding on a host and "concealed" antigens that are usually expressed...

Antigens of the sheep scab mite Psoroptes ovis.

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...

Reverse engineering the ovine gene network under Psoroptes Ovis infestation

Host preference of the sheep scab mite, Psoroptes ovis.

Sheep scab mites, Psoroptes ovis, collected from a Merino donor sheep, were used to infest Merino and Dorper sheep, and Angora and Boer goats. Mites were placed on the sheep on 1 or 2 occasions and on 5 occasions on the goats. All the animals were examined at regular intervals for the presence of scab lesions and living mites. Both sheep breeds developed lesions, but those on the Merino sheep w...

گزارش یک مورد بروز گری ناشی از آلودگی همزمان به مایت های Sarcoptes scabiei و Psoroptes ovis در یک گله گوسفند

Molecular characterization, expression and localization of a peroxiredoxin from the sheep scab mite, Psoroptes ovis.

The sheep scab mite, Psoroptes ovis, induces an intensely pruritic exudative dermatitis which is responsible for restlessness, loss of appetite and weight loss. Within the first 24 h of infection, there is a rapid inflammatory influx of eosinophils and apoptosis of the keratinocytes at the site of infection. The former cell type is capable of a sustained respiratory burst, toxic products of whi...
