ABSTRACT
Objective To investigate the pathogens and their drug resistance of neonatal skin infection in Maternal-Neonatal Unit to provide evidence for rational selection of antibiotics.Methods Secretions of skin lesions from newborns with skin infections delivered in Maternal-Neonatal Unit,Department of Obstetrics of Beijing Daxing People's Hospital from Jan.2009 to Dec.2010 were collected,cultured and identified for bacterial serotype.Antibiotic resistances of pathogens were determined.Enumeration data was presented by frequency and rate.The difference between groups was compared with Chi-square test.Results Two hundred and six newborn skin infection cases were diagnosed,which accounted for 2.3% of all newborns (n=9131) delivered in the hospital during the study period.Two types of skin infection were identified,impetigo (n=192,93.2%) and omphalitis (n=14,6.8%).Totally 154 pathogens were found,including 95 (61.7%) Gram-positive cocci and 59 (38.3 %) Gram-negative bacilli.The major pathogens among Gram-positive cocci were Staphylococcus aureus (45/154, 29.2%), followed by Staphylococcus epidermidis and Staphylococcus haemolyticus.Staphylococcus was sensitive to Cefazolin,Amoxicillin/clavulanic acid and Piperacillin/tazobactam,while resistant to Penicillin,Ampicillin and Erythromycin.The major pathogens among Gram-negative bacilli were Enterobacter cloacae (19/154,12.3%),followed by Escherichia coli and Klebsiella pneumoniae.Drug resistance rate of Gram-negative bacilli was high in penicillin,aminoglycosides and cephalosporins,while they were sensitive to piperacillin/tazobactam,Ampicillin/sulbactam,carbapenems and Quinolones.Conclusions Gram-positive cocci are the main pathogens of neonatal skin infection in the Maternal-Neonatal Unit,and among which Staphylococcus aureus is the major pathogen.Multi-drug resistance is common in the identified pathogens.Attentions should be paid to use antibiotics reasonably according to drug sensitivity test.
