Pathogen Epidemiology of Community-Acquired Pneumonia in Adults of Tangshan Area / 天津医药

ABSTRACT

Objective To investigate the distribution of pathogens in adult patients with community-acquired pneumonia (CAP) in Tangshan area. Methods The clinical data of 530 hospitalized patients with CAP were retrospectively collected in department of respiratory medicine from 6 hospitals in Tangshan area from October 2011 to September 2012. The sputum samples were isolated and cultured. Results A total of 195 strains were isolated from 530 patients with CAP. The most common types of pathogens included Klebsiella pneumoniae (64 strains,12.08%), Streptococcus pneumoniae (24 strains, 4.53%) and Bauman Acinetobacter (19 strain, 3.58%). The detective rates of Klebsiella pneumoniae and Pseudomonas aeruginosa were significantly higher in patients with basic diseases than those of patients without basic diseases (P0.05). Conclusion The gram-negative bacterial pathogens were the majority isolated from patients with CAP in Tangshan area. And Klebsiella pneumoniae was the primary bacteria. Patients with serious illness, above 60 years old, without antibiotic treatment before hospitalization, with basic diseases and above PORTⅢlevels should be given treatment of anti-gram-negative bacteria.
