Analysis of Bacterial Spectrum in Patients with Respiratory Tract Infection

Objective: To investigate the bacterial distribution in patients with respiratory tract infection,and provide evidence for using antibiotics.Methods: The distribution of 220 strains of pathogens detected from sputum culture of patients with respiratory tract infection was analyzed.Results: The positive rate of sputum culture was 31%.In total of 220 strains of bacteria,Gram-negative bacilli was 125 strains,and the percentage was 57%;Gram-positive cocci was 84 strains,and the percentage was 38%;fungus was 11 strains,and the percentage was 5%.Conclusions: Gram negative bacilli were the main pathogens in hospitalized patients with lower respiratory tract infection.Fungal infection was found in a certain proportion,and this must cause our attention.
