ABSTRACT
OBJECTIVE To isolate bacteria from three second-class hospitals in Zhenjiang Jiangsu Provine,to detect their drug(-resistance) to antibacterial(agents) and analyzed the results in order to find out pathogen distribution and drug(-resistance) trend of the common causative organism.METHODS We isolated 1661 strains of bacteria from clinical samples between 2002 and 2004,and analyze their drug-resistance.RESULTS The number of Gram-positive(bacteria) was 634,accounting for 38.2%,from them there were 312 strains of coagulase-negative Staphylococcus epidermidis,and 148(coagulase)-positive S.aureus.Drug-fast of two above staphylococci was similar.The(resistance) rate to penicillin and to oxacillin surpassed 85%,that to erythromycins exceeded 75%,to quinolones and cephalosporins surpassed 30% and 35%,respectively.The resistance rate to(vancomycin) was zero.Gram-(negative) bacteria were 1 027 strains,accounted for 61.8%.(According) to quantity order,the first was Enterobacter(249 strains);then were Klebsiella(226 strains);Escherichia(167 strains);Pseudomonas aeruginosa(136 strains);and Proteus(62 strains).The resistant rate to semisyhthesized penicillins among the first five Gram-(negative) bacteria species,was the most,especially the Proteus.CONCLUSIONS Clinical doctors,the(laboratorians) and detecting infection department in hospital should markedly pay attention to drug-resistant(bacterium) detection,pathogen mutation and drug-resistance trend,in(order) to reasonably use antibacterial(agents).
