The highest infection rate occurred in internal medicine wards(6.27%) . The most common infection site was lower respiratory tract(28.8%) ,followed by gastrointestinal tract(18.8%) . There were 263 pathogenic strains isolated from 322 clinical infectious specimens,among which the Gram-negative bacilli were predominant(42.97%) ,Gram-positive bacilli and fungus were 34.97% and 22.06% respectively.Conclusions The management of nosocomial infection must be enforced by supervising strictly the regulation of disinfection and isolation,rationalizing the usage of antibiotics to reduce the resistance of the germs.
