title: [Bacteria isolated from surgical infections and its susceptibilities to antimicrobial agents - Special references to bacteria isolated between April 2011 and March 2012].
abstract: Bacteria isolated from surgical infections during the period from April 2011 to March 2012 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 785 strains including 31 strains of Candida spp. were isolated from 204 (78.8%) of 259 patients with surgical infections. Five hundred and twenty three strains were isolated from primary infections, and 231 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. was highest, followed by Streptococcus spp. and Staphylococcus spp., in this order, from primary infections, while Enterococcus spp. was highest, followed by Staphylococcus spp. from surgical site infection. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae, Pseudomonas aeruginosa and Enterobacter cloacae, in this order, and from surgical site infection, E. coli was most predominantly isolated, followed by P. aeruginosa, K. pneumoniae, and E. cloacae. Among anaerobic Gram-positive bacteria, the isolation rate of Eggerthella lenta was the highest from primary infections, followed by Parvimonas micra, Collinsella aerofaciens, Lactobacillus acidophilus and Finegoldia magna, and from surgical site infection, E. lenta was most predominantly isolated, followed by P micra and L. acidophilus, in this order. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroidesfragilis was the highest from primary infections, followed by Bilophila wadsworthia, Bacteroides thetaiotaomicron, Bacteroides uniformis and Bacteroides vulgatus, and from surgical site infection, B. fragilis was most predominantly isolated, followed by Bacteroides caccae, B. thetaiotaomicron, Bacteroides ovatus and B. wadsworthia, in this order. In this series, vancomycin-resistant MRSA (methicillin-resistant Staphylococcus aureus), vancomycin-resistant Enterococcus spp. and multidrug-resistant P. aeruginosa were not observed. We should carefully follow up B. wadsworthia which was resistant to various antimicrobial agents, and also Bacteroides spp. which was resistant to many β-lactams.
