Pathogenic Bacteria in Senile Patients with Lower Respiratory Tract Infection: Their Distribution and Resistance / 中华医院感染学杂志

ABSTRACT

Stenotrophomonas maltophilia.At the same time 136 strains of fungi were isolated.Candida albicans was the most predominant accounted for 60.3%.50.7% Strains of K.pneumoniae and 75.7% strains of E.coli produced ESBLs.The resistance rates of all K.pneumoniae and E.coli to ?lactams were above 50%.All isolates of Enterobacteriaceae were sensitive to imipenem or meropenem.The activity of antibacterial agents against P.aeruginosa was coming down. CONCLUSIONS K.pneumoniae and E.coli are the major pathogens in senile patients with lower respiratory tract infection.Increasing of nonfermenters and fungi as an infection should bring great concern.
