Abstract:
OBJECTIVE:To investigate the situation of antibiotic resistance of S.pneumoniae(Sp)of clinical isolates from children in Guangzhou.METHODS:The authors cultured,isolated and identified the Sp strains from nasopharyngeal secretion of patients who visited Guangzhou children's hospitals because of upper respiratory tract infections in2000and2001.The paper strip method and E-Test of antibiotic susceptibility were done for157isolates.RESULTS:The penicillin resistant Sp(PRSP)isolates accounted for53.5%.PRSP isolates showed a higher resistance to other?-lactam antimcrobal,erythromycin and trimethoprim/sulfamethoxazole as compared to penicillin susceptible Sp(PSSP)isolates.More than90%of PRSP were mul?tidrug resistant strains.The strains of Sp were susceptible to amoxicillin/clavulamic acid and ceftriaxone.Strains had decreaced susceptibility(59%)to cefuroxime.In2001,the rate of cefaclor resistance was56%.The prevalence of erythromycin resistant Sp in this study was up to78%.The rate of tetra-cycline resistance were87.9%.Trimethoprim/sulphamethoxazole(TMP/SMX)resistant rate was as high as69%.The chloramphenicol resistant isolats were in stable low levels(33.3%).CONCLUSI_ ON:The resistant Sp isolated from children with respiratory tract infections in this area would be a severe problem.PRSP rate was increased and was characterized by a multi-resistance to erythromycin,tetracycline and TMP/SMX.
