SUMMARYThe mite fauna of dust from cloth-covered seats of four passenger trains and bedding from a British Rail linen store in Glasgow was investigated; 22 samples containing 4488 mg of dust from a total surface area of 5·5 m2 were taken. Sixteen samples were positive for mites and 33 specimens belonging to 10 species were found. The most common species were Dermatophagoides pteronyssinus (Trouessart), Glycyphagus domesticus (De Geer), G. destructor (Schrank) and Euroglyphus maynei (Cooreman). The species composition bore considerable resemblance to that of house dust (although the density of mites was far lower) and the mites have probably been transported from homes via clothing and pets. Only five intact specimens, which may have been alive at the time of sampling, were found. The dust from trains consisted mostly of particles of soot. Very few skin scales, the food source of house dust mites, were detected. The small numbers of intact mites found and the absence of an identifiable food source make it unlikely that permanent populations of mites survive in upholstered seats on trains.

Abstract. House dust mites are the most found allergens in homes scattered throughout the world that associated with allergic manifestations in the respiratory tract and skin, such as bronchial asthma, allergic rhinitis and atopic dermatitis. The most common house dust mite is from the family Pyroglyphidae, four of which have a close relationship with the incidence of allergy: Dermatophagoides pteronyssinus, Dermatophagoides farinae, Dermatophagoides microceras, and Euroglyphus maynei. This study aims to determine the type and density of house dust mites in several habitats in the homes of people with allergic diseases. This study is a descriptive study using cross-sectional method. Samples were dust in allergic patient’s home in Malalayang I, taken from three habitats, namely bed (mattress and bed linen), bedrooms floor and sofa, as many as 96 samples. Of the 96 samples, there are 60 samples positive of dust mites and 36 negative samples. This study found 157 mites (124 adults and 33 larvae mites). Of the 124 adult mites were identified, there are 122 from order Astigmata with the dominant species is Dermatophagoides pteronyssinus, and two others of the order Prostigmata. In each habitat that is in the bed (mattress and bed linen), bedrooms floor and sofa, Pyroglyphidae is the most prevalent.Keywords: house dust mite, allergiesAbstrak.

AbstractFrom houses and flats in Copenhagen inhabited by people allergic or non-allergic to house-dust, 69 samples of dust from mattresses have been collected and investigated for their content of mites and other arthropods. Three species of house-dust mites (Dermatophagoides pteronyssinus (Trt.), D. farinae Hughes, Euroglyphus maynei (Cooreman) Fain) were thus for the first time registered from Denmark besides some other mites and insects. The house-dust mites showed no preference for any of the rooms of the allergic patients nor for those of the controls (Table I). Outside the mattresses house-dust mites were found numerously below cross-bars, on wooden fillets and on floor panels beside the bed. In dust containing no skin scales living mites were not found; with air currents empty skins of mites had been transported around the room (Table 2). The house-dust mites are regarded ecologically to be the best adapted group of indoor mites to stand the low humidities (30-40 % R. H.) of centrally heated houses. Hypothetically it is proposed that the allergens of the house-dust mites are connected with the secretion of the lateral oil glands of hysterosoma.

Abstract This study was conducted to determine the influence of environmental factors on the prevalence of house dust mites in student dormitories of Bandar Abbas city. In this study, 64 dust samples were collected from seven randomly selected dormitories located in various areas of the Bandar Abbas. The collected mites were isolated and mounted in Hoyer’s medium and identified using a morphological key. The associations between the environmental factors and the density of house dust mites were investigated. In total, 1,093 adult mites were collected and identified. They consisted of four species including Dermatophagoides pteronyssinus Trouessart (57.6%), Dermatophagoides farinae Hughes (24.3%) and Dermatophagoides evansi Fain (14.9%) (Acari: Pyroglyphidae), and Cheyletus malaccensis Oudemans (3.2%) (Acari: Cheyletidae). All of the dormitories were contaminated by more than one house dust mites species and the mean density of house dust mites in dormitories was 8.3 ± 0.2 mites/g of dust. There was a significant relationship between average house dust mites density and some of environmental factors such as relative humidity, temperature, floor covering type, and number of occupants (P < 0.05). Results of this study revealed that two major allergenic dust mites, D. pteronyssinus and D. farinae, were the most prevalent and collected from all of dormitories and some of indoor environmental factors found to influence mites’ population.

Allergies in dogs have become a relatively frequent topic of discussion in veterinary surgeries. Many dogs, both purebred and of mixed breeds, are diagnosed for allergies. Allergies have many causes, from genetic predisposition to the environmental conditions in which the animal lives. Allergies in dogs are troublesome because they can lead to serious health complications when diagnosed late or left untreated. The results of the study support the hypothesis that the percentage of allergies to individual allergens varied by region (Tab. 4). Differences were observed in the case of Dermatophagoides pteronyssinus and Dermatophagoides farinae house dust mites, Acarus siro, and Tyrophagus. The remaining allergens caused allergic reactions in similar percentages of dogs from northern, central and southern Poland.

House dust mite was one of the most common allergens in homes around the world and associated with manifestations of allergies of skin and respiratory tract such as bronchial asthma, allergic rhinitis, and atopic dermatitis. This arthropod was commonly found on carpets, mattresses, children's toys, and other home furnishings. This study was aimed to identify and quantify the number of Dermatophagoides spp in Detention Center. This descriptive study was conducted using flotation method on 52 samples of mattress dust collected in February 2020. The results showed that 49 out of 52 mattress dust samples were positive of Dermatophagoidesspp..Of all Dermatophagoides spp, there were Dermatophagoides pteronyssinus (71.2%) and Dermatophagoides farinae (28.8%). In conclusion, this study found two species of Dermatophagoides spp. in Detention Center and suggested that the fascility maintain the cleanliness of the mattress by drying the mattress and changing the sheets at least once a week.

The growth of allergic diseases dictates the need to develop new forms of therapeutic allergens with high immunogenic and low allergenic activity. For many years, our laboratory has been developing drugs for the diagnosis and treatment of house dust mites (HDM) allergies. The purpose of this study is to summarize the results of the five-year development of therapeutic preparations of HDM allergens. During this period, we obtained the following forms of therapeutic allergens: a granular sublingual dosage form of a mixed allergen from Dermatophagoides pteronyssinus (Der.p) and Dermatophagoides farinaе (Der.f) and a succinylated monomeric HDM allergoid Der.p. The physicochemical and immunobiological properties of the obtained preparations were studied by methods: electrophoresis in PAGE in the presence of SDS-sodium, micropoint immunoblot, ELISA, inhibition of the binding reaction of allergen-specific IgE in the sera of patients. The research results showed that the obtained preparations have a reduced allergenic and increased immunogenic activity in comparison with native extracts. The created forms of mite allergens can be further used to treat patients sensitized to HDM of the genus Dermatophagoides.
