Objective To explore and analyze the etiologic analysis of 1 200 children under 5 years old with lower respiratory tract infections (LRTI) in Shangzhou city. Methods Sputa specimens for bacterial cultures were collected from 1 200 children with LRTI.The antibiotic susceptibility tests were performed after bacteria had been identified. Results Children under 3 months with LTRI had the highest positive rate of pathogen detection up to 75.9%.RSV infection was the most common virus for children under 3 months.K.pn was the most common bacterial for children followed by SP and E.coli.SP was sensitive to cephalosporins,rifampicin,chloromycetin and vancomycin.K.pn and E.coli were sensitive to imipenem. Conclusion The results of pathogen distribution and drug resistance are important to the diagnosis and treatment in lower respiratory tract infection.
