Abstract OBJECTIVE: To study the clinical features and antimicrobial resistance of community-acquired pneumonia caused by Klebsiella pneumoniae in infants. METHODS: The clinical data of 65 infants with community-acquired pneumonia caused by Klebsiella pneumoniae between 2007 and 2011 were retrospectively studied. RESULTS: Of the 65 infants, 37 cases (57%) were aged ≤3 months, 17 cases (26%) over 4 months, 7 cases (11%) over 7 months and 4 cases (6%) between 13 and 24 months. There were no significant differences in clinical manifestations and chest X-ray features between the infants with community-acquired pneumonia caused by Klebsiella pneumoniae and those with other bacterial pneumonia. Forty strains (62%) of ESBLs-producing Klebsiella pneumoniae were detected. Klebsiella pneumoniae was 100% sensitive to imipenem, meropenem and amikacin but resistant to penicillins and cephalosporins. The resistance rates of ESBLs-producing strains to penicillins, cephalosporins, amoxicillin/clavulanic acid, ampicillin/sulbactam, compound sulfamethoxazole, gentamycin, ciprofloxacin and aztreonam were significantly higher than for non-ESBLs-producing strains. ESBLs-producing strains also showed multiple-drug resistance. CONCLUSIONS: Community-acquired pneumonia caused by Klebsiella pneumoniae is common in infants aged ≤3 months. ESBLs-producing strains are prevalent in community-acquired pneumonia caused by Klebsiella pneumoniae and demonstrate both high rates of drug resistance and multiple-drug resistance.
