Four species of house dust mites recovered from houses of patients with allergic respiratory diseases

ABSTRACT

In the present study, 4 species of mites were isolated from the dust collected from the houses of patients with allergic respiratory diseases. The species were Dermatophagoides pteronyssinus, D. farinae, Ornithonyssus bacoti and Hemogamasus pontiger. The 2 species of Dermatophagoides were the predominant mites, which are known to produce the most potent allergens. Studying the serum immunoglobulins level showed that the IgE had a highly significant concentration among respiratory allergic patients [28] with [5] or without [23] atopic dermatitis. It was concluded that house dust mites, that cause inhalant allergens, are one of the main etiological factors of allergic respiratory diseases, with or without atopic dermatitis
