OBJECTIVE: To explore the method of rapid detection of skin fungi and the significance of conventional diagnosis liquor worker tinea corporis and tinea cruris using arbitrarily primed polymerase chain reaction AP-PCR.
METHODS: Among liquor workers who were 50 tinea corporis patients, 58 tinea cruris patients and 50 health persons, we amplified the DNAs of the dermatophytes were amplified using AP-PCR and random primers OPD18 5'-GAGAGCCAAC-3' and OPAA11 5'-ACCCGACCTG-3', at the same time, the dermatophytes with microscope were detected and cultured.
RESULTS: AP-PCR analysis detected fungal DNA in 45 patients(90.00%) among 50 liquor worker patients with tinea corporis, 31 patients(62.00%) had the positive results of microscope detection, and 41 patients(82.00%) had the positive results of standard culture. Among these workers who suffered from tinea corporis, T.rubrum, T.mentagrophyte, M. canis and E.floccosum were detected by AP-PCR. T.rubrum, T.mentagrophyte and M.canis were detected by standard culture. AP-PCR analysis detected fungal DNA in 53 patients(91.38%) among 58 liquor worker patients with tinea cruris, 37 patients(63.79%) had the positive results of microscope detection, and 48(82.76%) had the positive results of standard culture. Among the 58 workers who had tinea cruris, T.rubrum, E.floccosum and T.mentagrophyte were detected by AP-PCR and standard culture. Among 50 health persons, AP-PCR analysis detected fungal DNA in 3 persons(6.00%). The detection result with AP-PCR indicated that the kinds of fungi were T.rubrum and T.mentagrophyte. No one health person had the positive result in detection of fungi using microscope detection. Only one(2.00%) health person was detected to be infected by fungus with cultural way. The kind of fungus was T.rubrum.
CONCLUSION: AP-PCR is a rapid, sensitive and specific detection method for occupational dermatophyte patients. It can be used to detect and diagnose professional dermatophytosis.
