Abstract:
OBJECTIVE To investigate the drug resistance of Gram-positive organisms infection in our hospital and offer scientific basis for reasonable usage of antibiotics.METHODS The 318 strain organisms were isolated from the specimens of Aikang Hospital since Jan 2001 to Dec 2005.Gram-positive organisms were isolated from the specimens by the routine methods.The drug susceptivity was tested by K-B method.We got the results by 1999 standard of NCCLS.RESULTS Among the 318 strains,Staphylococcus aureus were 128 strains,40.3% of the total organisms;coagulase-negative S.aureus were 69 strains,21.7% of the total organisms;Enterococcus faecalis were 67 strains,21.1% of the total organisms;meticillin-resistant S.aureus(MRSA) were 32.8%;Meticillin-resistant coagulase-negative S.aureus(MRCNS) were 29.0%.The results of drug sensitivity test showed the drug resistant rate of Gram-positive strains for commonly used antibacterials was lower than in Shenzhen,Beijing,Shanghai,Wuhan,Guangzhou and other cities.CONCLUSIONS We should attach in our city importance to supervise the drug-resistance of Gram-positive organism,and preclude dissemination and epidemic of drug resistant strains.
