Abstract:
OBJECTIVE To investigate the genes of disinfectant-sulfadiazine and antibiotic resistance of Escherichia coli strains in elderly wards.METHODS Polymerase chain reaction and dilution test were used to detect and analyze the disinfectant-sulfadizane drug resistance gene and drug resistance of the E.coli.RESULTS From 30 E.coli strains isolated from elderly patients,21 were detected carrying disinfectant-sulfadizine drug resistance genes,and the positive rate of qacE△1-sulⅠ was 70.0%.CONCLUSIONS The detection rate of disinfectant-sulfadiazine drug resistance gene from E.coli strains isolated from elderly patients,the bacteria detection rates are relatively high.Most of the isolates were resistant to commonly used antibiotics.It suggests that clinical drug-resistant strains may be resistant to disinfectants.This condition should be paid much attention by disinfection wotkers of our country.
