Abstract:
Objective To understand the prevalence,drug resistance and clinical features of children with acute lower respiratory tract infection(ALRI) caused by escherichia coli.Methods From Oct. 2005 to Oct. 2006,659 patients with ALRI who were admitted to hospital were chosen and their nasopharyngeal secretions were obtained and cultured.K-B disc diffusion for antibiotic susceptibility were performed for these clinical isolates.Results Among 659 patients,118 cases were isolated escherichia coli,the rate was 17.99% which had 90 boys and 28 girls.Eighty-seven of 118 E.coli strains were with extended-spectrum ?-lactamase(ESBLs),the rate was 73.73%.All of strains were sensitive to imipenem.For ESBLs-producing strains,the ratio of resistance tocefotaxime,ceftriaxone,cefuroxime,ampicillin,piperacillin were 78.81%,73.73%,73.73%,76.27%,78.81%,respectively.Conclusions The positive rate of ESBLs producing E coli in Kunming area is high and drug resistance is severe gradually.Imipenem can be the first selection for treatment on these infections.
