Abstract

  Background: Bacterial pneumonia has been a medical burden, especially on hospitalized patients. The situation of multidrug-resistant bacteria has been a very emergency problem in treatment facilities. Objective: Detect the proportion of isolated bacterial strains from pneumonia patients at Da Nang C hospital and survey the antibiotic resistance of common strains of pneumonia-causing bacteria. Materials and methods: A cross-sectional descriptive study was conducted on 89 strains of bacteria isolated from patients with pneumonia at Da Nang C Hospital. Strains of bacteria that cause pneumonia were identified by a set of chemical organisms and antibiotic resistance was detected using the Kirby-Bauer technique. Results: In 89 isolated strains of bacteria, Gram-negative bacteria accounted for 93%; Gram-positive bacteria account for 7%. Pseudomonas aeruginosa was more than 30% resistant to group A and B antibiotics. Acinetobacter baumannii was resistant over 80% to antibiotics in the aminoglycoside group, the cephalosporin group and the carbapenem group. Klebsiella pneumoniae produced ESBL at a rate of 70.83%. The MRSA rate of Staphylococcus aureus was 100%, the bacteria was completely resistant to most group A antibiotics but sensitive to vancomycin and linezolid. Conclusion: The common pneumonia triggers were Gram-negative bacteria; the strains of bacteria were moderately resistant to the antibiotics.
