title: [Bacteria isolated from surgical infections and its susceptibilities to antimicrobial agents--special references to bacteria isolated between April 2010 and March 2011].
abstract: Bacteria isolated from surgical infections during the period from April 2010 to March 2011 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 631 strains including 25 strains of Candida spp. were isolated from 170 (81.7%) of 208 patients with surgical infections. Four hundred and twenty two strains were isolated from primary infections, and 184 strains were isolated from surgical site infection. From primary infections, anaerobic Gram-negative bacteria were predominant, followed by aerobic Gram-negative bacteria, while from surgical site infection aerobic Gram-positive bacteria were predominant, followed by anaerobic Gram-negative bacteria. Among aerobic Gram-positive bacteria, the isolation rate of Enterococcus spp. such as Enterococcus faecalis, Enterococcus faecium, and Enterococcus avium was highest, followed by Streptococcus spp. such as Streptococcus anginosus and Staphylococcus spp. such as Staphylococcus aureus, in this order, from primary infections, while Enterococcus spp. such as E. faecalis and E. faecium was highest, followed by Staphylococcus spp. such as S. aureus from surgical site infection. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae, Klebsiella oxytoca, Enterobacter cloacae, and Pseudomonas aeruginosa in this order, and from surgical site infection, E. coli and R aeruginosa were most predominantly isolated, followed by E. cloacae and K. pneumoniae. Among anaerobic Gram-positive bacteria, the isolation rates of Parvimonas micra, Eggerthella lenta, Streptococcus constellatus, Gemella morbillorum, and Collinsella aerofaciens were the highest from primary infections, and the isolation rate from surgical site infection was generally low. Among anaerobic Gram-negative bacteria, the isolation rate of Bilophila wadsworthia was the highest from primary infections, followed by, Bacteroides fragilis and Bacteroides ovatus, and from surgical site infection, B. fragilis was most predominantly isolated, followed by Bacteroides thetaiotaomnicron, in this order. In this series, vancomycin-resistant MRSA (methicillin-resistant S. aureus), vancomycin-resistant Enterococcus spp. and multidrug-resistant P. aeruginosa were not observed.
