AIM: To explore the characteristics of diarrhea caused by acaroid mites.METHODS: Acaroid mites in fresh stools of 241 patients with diarrhea were separated by flotation in saturated saline.Meanwhile, skin prick test, total IgE and mite-specific IgE were detected in all patients.RESULTS: The total positive rate of mites in stool samples of the patients was 17.01% (41/241), the positive rates of mites in male and female patients were 15.86 % (23/145)and 18.75 % (18/96), respectively, without significant difference (P＞0.05). The percentage of skin prick test as ″+++″″++ ″″+ ″″±″″-″ was″+++, ″++″,″ +″, ″±″ and ″-″was 9.13 % (22/241), 7.47 %(18/241), 5.81% (14/241), 4.98 % (12/241) and 72.61%(175/241), respectively. The serum levels of total IgE, mitespecific IgE in patients with and without mites in stool samples were (165.72±78.55) IU/ml, (132.44±26.80) IU/ml and (145.22±82.47) IU/ml, (67.35±45.28) IU/ml,respectively, with significant difference (P＜0.01). The positive rate of mites in stool samples in staffs working in traditional Chinese medicine storehouses or rice storehouses (experimental group) was 26.74 % (23/86), which was significantly higher than that (11.61%, 18/155) in people engaged in other professions (X2=8.97, P＜0.01).CONCLUSION: Acaroid mites cause diarrhea and increase serum levels of total IgE and mite-specific IgE of patients,and the prevalence of diarrhea caused by acaroid mites is associated with occupations rather than the gender of patients.

CONCLUSION:Acaroid mites cause diarrhea and increase serum levels of total IgE and mite-specific IgE of patients, and the prevalence of diarrhea caused by acaroid mites is associated with occupations rather than the gender of patients.
