RESUMO
OBJECTIVE To explore the isolation,distributive characteristics and drug resistance of Acinetobacter baumannii producing AmpC enzyme in nosocomial infection.METHODS The distributive sections and infected parts of 42 A.baumannii strains in nosocomial infection were analyzed,and three dimensional test was used to(detect) AmpC enzyme.RESULTS Among them 18(42.86%) strains were AmpC positive.Among 40 strains of A.baumannii in non-nosocomial infection,6(15.00%) strains were AmpC positive.A.baumannii in nosocomial(infection) in clinical sections was mainly discovered in burn department,and the respiratory tract and skin soft tissue were the main infected sites(90%).The drug resistance in nosocomial infection was obviously higher than that of A.baumannii in non-nosocomial one.CONCLUSIONS The isolated rate and drug resistance rate of A.baumannii producing AmpC enzyme are rather high in nosocomial infection.It′s(neccessary) to take measures to prevent the nosocomial infection caused by A.baumannii.
