Mite allergen exposure has been widely related to sensitization and development of allergic diseases. This study intended to evaluate the degree of allergen exposure in Uberaba, Brazil, through the measurements of Der f 1 and Der p 1 allergen levels associated with the acarologic analysis in house dust samples. A total of 240 dust samples were collected from 60 houses through vacuuming sofas an...

In more than 20% of the world population, sensitization to house dust mite allergens triggers typical allergic diseases such as allergic rhinitis and asthma. Amongst the 23 mite allergen groups hitherto identified, group 1 is cysteine proteases belonging to the papain-like family whereas groups 3, 6, and 9 are serine proteases displaying trypsin, chymotrypsin, and collagenolytic activities, res...

The effectiveness of oxalic acid (OA) and Sucrocide (S) (AVA Chemical Ventures, L.L.C., Portsmouth, NH) in reducing populations of the varroa mite Varroa destructor Anderson & Trueman (Acari: Varroidae) in honey bee, Apis mellifera L. (Hymenoptera: Apidae) colonies was measured under the desert conditions of Arizona, USA. OA and S were applied three times 7 d apart. A 3.2% solution of OA was ap...

BACKGROUND Published studies relating pyrethroid use and subsequent mite outbreaks have largely been based on laboratory and field experiments, with some inferring a result of increased miticide use. The present study derived a mathematical model proposed to quantify the effect of pyrethroid use intensity on mite population density. The model was validated against and parameterized with actual ...

Background: House dust mite is common aeroallergen. It can cause type 1 allergy (IgE-mediated) symptoms from dust inhalation with different spectrums of the disease. The relationship between migraine headache and aeroallergen has been questioned for many years. Objective: To report a case of migraine headaches in a child due to house dust and mite allergy and the course of this allergy after sp...

BACKGROUND Sublingual immunotherapy (SLIT) as a therapy for the treatment of allergic rhinitis in children might be acceptable as an alternative for subcutaneous immunotherapy. However, the efficacy of SLIT with house dust mite extract is not well established. OBJECTIVE To investigate whether SLIT in house dust mite-allergic children recruited in primary care is effective and safe. METHODS ...

Identification and eradication of murine fur mite infestations are ongoing challenges faced by many research institutions. Infestations with Myobia musculi and Myocoptes musculinus can lead to animal health problems and may impose unwanted research variables by affecting the immune and physiologic functions of mice. The purpose of this study was to evaluate the utility and efficacy of soiled be...

Colony Collapse Disorder has become a global problem for beekeepers and for the crops which depend on bee polination. Multiple factors are known to increase the risk of colony colapse, and the ectoparasitic mite Varroa destructor that parasitizes honey bees is among the main threats to colony health. Although this mite is unlikely to, by itself, cause the collapse of hives, it plays an importan...

migratory birds are most often responsible for the distribution of avian diseases in different areas and serve as hosts for most parasites, including ectoparasites. the aim of the present study was to record the distribution range of a mesostigmatic mite species, dermanyssus gallinae in barn swallow nests in urmia suburb, north west of iran. the samples were collected from 161 bird nests in 44 ...

background: dermatophagoides farinae and dermatophagoides pteronyssinus are house dust mites (hdm) that they cause severe asthma and allergic symptoms. tropomyosin protein plays an important role in mentioned immune and allergic reactions to hdms. here, tropomyosin protein from dermatophagoides spp. was comprehensively screened in silico for its allergenicity, antigenicity and similarity/conser...
