Abstract:
OBJECTIVE To study the distribution and drug resistance of the cancer patient′s pathogenic bacteria.METHODS The clinical nosocomial infection of 1451 cancer patients was analyzed by using the soft WHONET-5.RESULTS Of 955 strains isolated from sputa,the G-bacilli were 31.2%,and their main bacteria were Pseudomonas aeruginosa and Klebsiell pneumoniae,the G+ coccis were 31.2%,and their main bacteria were Staphylococcus epidermidis,and the fungi were 43.3%,and their main molds were Candida.albicans.Of 284 strains isolated form stool,the G-bacilli were 64.4%,and their main bacteria were Eschericha coli,the G+ cocci were 10.2% and their main bacteria were S.epidermidis,and fungi were 25.5%.Of 72 strains isolated from blood,the G-bacilli were 62.5%,and their main bacteria were E.coli,the G+ cocci were 30.5% and the fungi were 7.0%.Of 140 strains isolated from pharyngeal swab,the G-bacilli were 15.0%,and the G+ cocci were 43.0% and the fungi were 42.0%.The results of sensitivity tests showed as followed: The G-bacilli had a highly sensitive to imipenem,and had a high drug resistance against the first and second generation cephalosporin,ampicillin,piperacillin.The G+ cocci were highly sensitive to vancomycin and had a high drug resistance against oxacillin,penicillin,and erythromycio,the fungi had an obvious drug resistance against azoles.CONCLUSIONS It is high prevalence of ESBLs among MRS,and Staphylococcus.The application and selection of antibiotics must be based on the results of sensitivity tests,and the drug resistance of pathogenic bacteria must be controlled.
