Objective:This study was carried out to detect house dust mites in houses and to investigate group 1 antigens of Dermatophagoid species in Ordu, Giresun, Trabzon and Rize provinces of the Central and Eastern Black Sea Region.Methods:Dust samples obtained from the beds were subjected to both microscopic and antigenic examination. Samples prepared by the lactic acid method for microscopic examination were evaluated under a light microscope. Antigenic analysis was performed by investigating Der p 1 and Der f 1 belonging to D. pteronyssinus and D. farinae by ELISA test.Results:90.3% of the dust samples were evaluated positive by microscopic examination (10x, 40x) and 149 mites were detected. D. pteronyssinus 74%, D. farinae 13%, Dermatophagoides spp. growth forms 5%, Cheyletus spp. 1%, E. maynei 1%, C. arcuatus 1%, T. putrescentiae 1%, L. destructor 1% and unidentified mites were detected at the rate of 3% respectively. Der p 1 antigen was detected in 93% and Der f 1 antigen in 84.7%. The highest amount of antigen detected in one gram of powder was 1,272 μg for Der p 1 and 0,482 μg for Der f 1.Conclusion:No difference was observed between mite species and distribution in the provinces where the study was conducted (p

Objective:The aim of this study was to determine the species of house dust mites and their prevalence in Giresun.Methods:Dust samples taken from 15 houses which were visited monthly for one year were examined by the lactic acid method.Results:A total of 2251 mites were detected in the study. The distribution of mites was as follows: 81.8% Dermatophagoides pteronyssinus, 0.5% Dermatophagoides farinae, 0.04% Euroglypus maynei (E. maynei), 4.2% Dermatophagoides spp. 0.06% A. siro, 2.4% Glycphagus domesticus, 0.9 % Lepidoglyphus destructor, 1.4% Tyrophagus putrescentiae, 4.5% Campunatus arcuatus, 1.3% Cheyletus spp. Pyroglyphid species were detected in all houses (100%). Dermatophagoides pteronyssinus was found in 100%, D. farinae 5% and E. maynei 4% of the houses.Conclusion:The mites in Giresun were found in all houses throughout the year and were detected in all of the samples. Although they were detected in greater amounts in the spring and summer, only a moderate relationship could be detected with temperature. In August-October period, mite existence was significantly higher than the January-March period (p
