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. Tungau debu rumah (TDR) adalah alergen dalam rumah terbanyak yang tersebar di seluruh dunia yang dikaitkan dengan manifestasi alergi pada saluran pernapasan dan kulit, seperti asma bronkial, rinitis alergi dan dermatitis atopik. TDR yang paling sering ditemukan adalah dari famili Pyroglyphidae, empat di antaranya memiliki hubungan yang erat dengan kejadian alergi: Dermatophagoides pteronyssinus, Dermatophagoides farinae, Dermatophagoides microceras, dan Euroglyphus maynei. Penelitian ini bertujuan untuk mengetahui jenis dan kepadatan tungau debu rumah pada beberapa habitat di rumah penderita penyakit alergi. Penelitian ini adalah penelitian deskriptif dengan menggunakan metode cross-sectional. Sampel penelitian adalah debu di rumah penderita alergi di Kelurahan Malalayang I yang diambil dari 3 habitat, yaitu tempat tidur (kasur dan sprei), lantai kamar tidur, dan sofa sebanyak 96 sampel. Dari 96 sampel, 60 sampel positif tungau debu dan 36 sampel negatif. Pada penelitian ini ditemukan 157 tungau (124 tungau dewasa dan 33 larva). Dari 124 tungau dewasa yang terindentifikasi, dari ordo Astigmata sebanyak 122 dengan spesies yang dominan adalah Dermatophagoides pteronyssinus, dan dua lainnya dari ordo Prostigmata. Pada masing-masing habitat yaitu di tempat tidur (kasur dan sprei), lantai kamar tidur dan sofa, famili Pyroglyphidae paling banyak ditemukan.Kata kunci: tungau debu rumah, alergi

AbstractHouse dust mites live in house dusts and affect the health of humans. Among the many species, Dermatophagoides farinae, D. pteronyssinus, and Euroglyphus maynei have been found to be commonly associated with Ig-E-mediated allergic diseases. As a result, there is increasing effort to develop methods for the diagnosis and treatment of diseases caused by these species. The purpose of the current study was to explore the evolutionary relationships among house dust mites. After adult D. farinae were separated and isolated for total RNA extract, the cDNA coding for Der f 1 and Der f 2 were cloned and sequenced. Then amino acid sequences for group 1 and 2 allergens of two of the most common house dust mites, D. pteronyssinus, E. maynei, were obtained from databases. Interestingly, homological analysis of amino acid sequences showed that both Der p 1 and Der p 2 from D. pteronyssinus had more similarities to Eur m 1 and Eur m 2, respectively, than they had to Der f 1 and Der f 2 from D. farinae. In the phylogenetic trees, D. pteronyssinus clustered with E. maynei, but not with D. farinae, although D. pteronyssinus and D. farinae belong to the same genus according to morphological taxonomy. It was previously assumed that D. pteronyssinus was more similar to E. maynei than to D. farinae at evolutionary levels.

Feeding Interactions

Abstract The feeding interactions between house dust mites (HDM) and microorganisms are key factors in the survival of mites in human environments. The suitability of different microbes for HDM is not known. Here, microbial species isolated from HDM cultures were offered to HDM in food preference tests under laboratory conditions. The microbial species were added to the rearing diet of mites to reach 7% of Saccharomyces cerevisiae and 10% of each tested microorganism. The suitability of each microbe-supplemented diet for Dermatophagoides pteronyssinus and Dermatophagoides farinae was compared in terms of mite population growth and mite preference in a cafeteria test. The effect of mite feeding on the respiration of microorganisms in the diet was observed in microcosms. HDM were able to feed and reproduce on some bacterial and fungal species, but the suitability of microbial species differed. Increasing the yeast Sa. cerevisiae in the diet from 7 to 17% appeared the most suitable for both mite species. Staphylococcus spp. bacteria were preferred for D. farinae and were suitable for reproduction. The population growth and feeding preferences of D. pteronyssinus and D. farinae with respect to microorganisms indicate that D. farinae can develop on a diet with bacterial (Staphylococcus nepalensis and Staphylococcus kloosii) additions, whereas D. pteronyssinus was successful on a diet with fungal (Aspergillus jensenii and Aspergillus ruber) additions. The bacteria Kocuria rhizophila and Bacillus cereus decreased population growth in D. pteronyssinus, whereas the yeasts Hyphopichia pseudoburtonii, Hyphopichia burtonii, and Candida ciferrii decreased population growth in D. farinae. These results indicate that some microorganisms are an important food source for HDM.

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.
