Objective To investigate the clinical characteristics and antimicrobial resistance of Acinetobacter baumannii(A.baumannii) in neonatal intensive care units (NICUs).Methods The clinical isolation and antimicrobial resistance of A.baumannii causing healthcare-associated infection(HAD in 4 NICUs of a hospital from October 2012 to October 2014 were analyzed statistically.Results A total of 11 640 neonates were admitted in 4 NICUs,500(4.3 ％) developed HAI,51 (10.2 ％) developed 52 cases of A.baumannii infection.Distribution of A.baumannii infection was as followsNICU of extremely premature infants,premature infants,full-term infants,and surgical NICU were 42,1,4,and 5 cases respectively.Incidences of A.baumannii HAI in 4 seasons were compared,difference was statistically significant(x2 =16.05,P＜0.05),infection mainly occurred in the spring and summer.A.baumannii had high resistance rates to β-1actam antibiotics (such as piperacillin/sulbactam,cefepime,imipenem)and gentamycin(＞90 ％),resistance rate to amikacin was the lowest (51.9 ％).Among 52 strains of A.baumannii,46 were multidrug-resistant strains,and 3 were extensively drug-resistant strains.Conclusion A.baumannii HAI is most serious in NICU of extremely premature infants,resistance rates to commonly used antimicrobial agents are high.
