Introduction:
The home environment is one of the most favorable spaces for the development of mites because of its low light, humidity, and temperature. Thus, it contributes to the growing cases of allergies among atopic individuals.Objective:
To investigate the faunal profile of house dust mites in the city of Rio de Janeiro and the allergenic potential in this region.Methods:
Thirty dust samples were collected from homes in the city of Rio de Janeiro, and the species found were classified according to their morphology, family, and genus by classification key. For the collection region, the total protein level was assessed by the Lowry method and electrophoresis under denaturing conditions (SDSPAGE).Results:
There was a predominance of Pyroglyphidae mites, accounting for 84.9% of samples; Tyrophagus putrescentiae accounted for 8%, Blomia tropicalis for 6%, Cheyletus malaccensis for 1%, and Acarus siro for 0.1%. The allergen protein content of the samples was the following group 1 25 kDa (Der 1, Der p 1, and Blo t 1), group 2 15 kDa (Der f 2, Der 2, Tyr p 2, and Blo t 2), and group 3 29-30 kDa (Der f 3 and Blo t 3), which indicates that people in this region are susceptible to sensitization to these mites.Conclusion:
Knowledge of the mite fauna in the region under study allows the guidance of health care professionals to perform skin tests for specific mites and conduct treatment according to the pool of mite extracts containing antigens, making immunotherapy more effective.
