ABSTRACT
OBJECTIVE To investigate the distribution and drug resistance of pathogenic bacteria which caused respiratory infection among suscepted patients and offer scientific basis for reasonable usage of antibiotics.METHODS Oropharyngeal swabs among 709 cases of respiratory infection neonates were investigated by the routine methods and drug resistance was analyzed by K-B method.RESULTS Totally 438 bacterial strains were isolated from 709 neonates.most of these bacteria were Gram-negative bacilli(70.3%),among which Haemophilus influenzae and Klebsiella pneumoniae were accounted for 39.8% and 10.3%,respectively;fungi and Gram-positive cocci were accounted for 23.5% and 6.2%.CONCLUSIONS Most strains present higher resistance rates to penicillin and ampicillin;but cefoxitin,amikacin,vancomycin,imipenem and the third generation cephalosporins are revealed with higher sensitivity rates for pathogenic bacteria in newborns.
