Fifty-four White Rock hens were infested with 2,000 northern fowl mites/ bird and six hens were sampled at nine time periods during the 28,week study. Hens supported an average of 15,028 mites when mites were collected from infested bird carcasses digested with a modification of the Cook's technique. Mite-specific Ilrccipitating antibodies were quantified from hen serum samples with rocket elec...

Tyrophagus putrescentiae (Schrank, 1781) is an emerging source of allergens in stored products and homes. Feces proteases are the major allergens of astigmatid mites (Acari: Acaridida). In addition, the mites are carriers of microorganisms and microbial adjuvant compounds that stimulate innate signaling pathways. We sought to analyze the mite feces proteome, proteolytic activities, and mite-bac...

A chimeric human IgE monoclonal antibody was developed against the house dust mite allergen Der p 2. This chimeric antibody (hIgE-Dp2A) was composed of the heavy-chain variable domains and light chains of the original murine monoclonal antibody retaining its binding characteristics, whereas the heavy-chain constant domains were exchanged with the human IgE heavy chain. The chimeric IgE expressi...

Mange is a contagious skin disease affecting various groups of animals. Psoroptic mange severe condition farm animals; it highly and responsible for huge economic losses in many Infestation with Psoroptes has been reported all over the world animals, but none ever swine. A male weaner large white breed pig age 3 months weighing 10kg was presented lesions areas alopecia during routine visit by h...

The enzyme amylase was shown to be present in extracts prepared from both house dust and spent growth medium used in the culture of the mite Dermatophagoides pteronyssinus. In dust, it was shown to correlate with both mite counts and concentrations of the faecally derived mite allergen, Der p I. Mite amylase was isolated from the culture medium and shown to be a single chain protein with a mole...

This nation-wide survey including 382 Swedish apiaries is the first to document base-line information of prevalence and distribution ectoparasitic mite Varroa destructor, mite-associ...

Miniature inverted-repeat transposable elements (MITEs) are ubiquitous, non-autonomous class II transposable elements. Here, we conducted genome-wide comparative analysis of 20 MITE families in B. rapa, B. oleracea, and Arabidopsis thaliana. A total of 5894 and 6026 MITE members belonging to the 20 families were found in the whole genome pseudo-chromosome sequences of B. rapa and B. oleracea, r...

Scabies is a parasitic infestation of the skin by the mite Sarcoptes scabiei that causes significant morbidity worldwide, in particular within socially disadvantaged populations. In order to identify mechanisms that enable the scabies mite to evade human immune defenses, we have studied molecules associated with proteolytic systems in the mite, including two novel scabies mite serine protease i...

The wheat curl mite, Aceria tosichella Keifer, transmits at least three harmful viruses, wheat streak mosaic virus (WSMV), high plains virus (HPV), and Triticum mosaic virus (TriMV) to wheat (Triticum aestivum L.) throughout the Great Plains. This virus complex is considered to be the most serious disease of winter wheat in the western Great Plains. One component of managing this disease has be...

BACKGROUND The prevalence of allergic diseases, particularly asthma and allergic rhinitis, has increased tremendously in Thailand and worldwide. House dust mite (HDM) is the major IgE sensitizer among allergic children and adults. We have developed local standardized mite allergen extracts, Siriraj Mite Allergen Vaccine (SMAV) from Dermatophagoides pteronyssinus (Dp) and Dermatophagoides farina...
