[Adult hospital acquired pneumonia: a multicenter study on microbiology and clinical characteristics of patients from 9 Chinese cities].

Abstract

Common pathogens were A. baumannii, P. aeruginosa, S. aureus and K. pneumonia. The common bacteria of HAP in China showed high resistance rates to antibiotics.
