“…In populations at risk, such as agriculture workers dealing with fruit trees or greenhouse vegetables, the sensitization rates are high, in the range of 36% [13] to 100% [32]. Epidemiologic studies have also demonstrated high rates of sensitization in the surrounding population, which is not occupationally exposed to apple trees [21] or citrus trees [24][25][26]. Significant differences in the rate of sensitization to these mites have also been identified between children residing in rural or urban areas [33].…”

“…Among the mites present in horticultural environments, the following have clinical importance: phytophagus mites belonging to the family Tetranychidae [10][11][12][13][14][15][16][17][18][19][20] (genera Tetranychus and Panonychus) [21][22][23][24][25][26], and predator mites belonging to the families Phytoseiidae (genera Phytoseiulus and Amblyseius), Dermanyssidae (genus Hypoaspis) [27,28,29•], and Hemisarcoptidae (genus Hemisarcoptes) [30]. The main symptoms associated with sensitization and exposure to Tetranychidae mites (red spiders) are rhinoconjunctivitis and asthma.…”

There is an increasing awareness of the health implications of mite sensitivity, as it is closely related to asthma. Mite allergy constitutes a complex worldwide problem, with sanitary and economical implications. Not only are mite species present in house dust, producing potent allergens, but other, less studied species are also responsible for significant allergic reactions in occupational settings. In this review, we focus on the growing number of mite species that are implicated in allergic cutaneous and respiratory diseases in humans. Mite allergy is not restricted only to the human "indoor" environment, because numerous reports clearly demonstrate that many species that can induce sensitization and symptoms are encountered in occupational settings. An important component of allergy research is the evaluation of the allergenic cross-reactivity to verify to what extent different mite species have unique, species-specific, or cross-reactive allergens. The results of these investigations have important clinical consequences for the diagnosis and treatment of allergic diseases. Internationally standardized mite extracts are needed to compare sensitization rates around the world and clearly establish risk factors associated with sensitization and asthma. In spite of recent controversial results, a significant reduction in the exposure to mite allergens continues to be an important challenge and one of the main goals in the treatment of mite-induced respiratory symptoms. In many cases, this reduction must be achieved in the workplace as well as in the home environment.

This paper highlights a clinical case of a patient suffering bronchial asthma and rhinoconjunctivitis due to sensitization to Tetranychus urticae (TU), commonly known as the red spider mite, which belongs to the Prostigmata sub-order of the Tetranychidae family, in relation to a work environment (a carnation nursery). Both prick and intradermal skin tests were positive, as well as specific bronchial challenge tests with TU extract. Specific IgE was demonstrated by RAST (Class 3). Unspecific bronchial provocation with methacholine was negative. Sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE) immunoblotting revealed the presence of seven main IgE binding proteins, the more intense bands being those appearing at 21, 17 and 15 kDa. This indicates a case of immediated type hypersensitivity to Tetranychus urticae with a clear correlation to occupational environment.

“…9,10 All previous TSM-related reports have been confined to occupational exposures. [2][3][4][5][6][7][8] Although house-dust mite (HDM) has been known as the most important allergen in Korea, 11 a recent investigation demonstrated that TSM could be one of the prevalent inhalant allergens in nonfarmers as well as farmers in pear orchards. 12 Skin prick test (SPT) results of adult asthmatic patients complaining of summer-type asthma indicated that TSM was second in prevalence of sensitivity to HDM.…”
