Abstract: Objective To investigate acarine fauna and correlation between mite density and allergen concentration in dust samples from asthma patients in the city of Haikou.Methods House dust samples were collected from asthma patients, then mites were identified and counted,and were detected for allergen concentrations Der P1.Results A total of 616 slides were made and identified as sixteen species of mites,the percentage of Blomia tropicalis and Dermatophagus pteronyssinus were 71.75% and 9.25%,respectively.The densities and mite allergen concentrations were higher in the samples from asthma patients than those in normal control group with significant difference(P<0.01).The correlation between mite density and allergen concentration was significant, too(r=0.716,P<0.01).Conclusion Blomia tropicalis is dominant in this area,and detection for mite allergen concentrations Der P1 may take place of mite counts to evaluate the mite pollution in house dust.
