Abstract:
OBJECTIVE To investigate pathogenic bacteria isolated from children with respiratory tract infection and bacterial resistance to commonly used antimicrcrobial agents. METHODS Routine methods were used to isolate and identify fastidious bacteria and Streptococcus from children throat swabs. The drug susceptibility tests were performed by Kirby-Bauer method. RESULTS One hundred and twenty four pathogenic bacteria were isolated from 300 samples. The isolation rate was 41.3% and the fastidious bacteria were 78 strains(62.9%). The resistant rate of Haemophilus influenzae to clarithromycimn, trimethoprim-sulfamethoxazoe(SXT) and ampicllin was 70.0%, 60.0%and 66.7%, respectively. The resistant rate of Streptococcus pneumoniae to tetracycline, clindamycin, SXT and azithromycin was 96.2% 92.3% 92.3% and 92.3%, respectively; the resistant rate of Streptococcus pyogenes to tetracycline, clidamycin and azithromyoin was 100.00%, 94.45% and 83.33%, respectively. CONCLUSIONS Fastidion bacteria and S. pyogenes are the main Pathogenic bacteria in children with respiratory tract infection. The antimicrobial agents should be chosen according to antimicrobial sasceptibility test results.
