title: [Evolution of resistance to antibiotics from 1997 to 2005 in the Reunion Island].
abstract: OBJECTIVE
  The groupe hospitalier Sud Reunion (GHSR) is a 1130-bed hospital center, located on the Reunion Island, (Indian Ocean). We studied the profiles of antibiotic resistance in 2005, and compared those with previous data collected in 1997-1998, and with Metropolitan France and European data.
  
  
  METHODS
  All bacteriological strains isolated from diagnostic samples in 2005 were analyzed according to CA-SFM recommendations.
  
  
  RESULTS
  Since 1997, the rates of resistance to enterobacteria (betalactam, aminoside, quinolone, trimethoprim-sulfamethoxazole), Pseudomonas aeruginosa (ticarcillin, amikacin, ciprofloxacin, fosfomycin), Acinetobacter baumanii (amikacin) has decreased significantly. The rate of methicillin-resistant Staphylococcus aureus (1997: 3.6 %, 2005: 13.4 %) has increased but less than in Metropolitan France. The rate of Streptococcuspneumonia with decreased susceptibility to penicillin has increased (1997: 25.5 %, 2005: 42.9 %), as for Haemophilusinfluenzae which present an important increase of betalactam resistance (1997: 15.5 %, 2005: 37.8 %).
  
  
  CONCLUSIONS
  By comparing our data to 1997 and Metropolitan French data, it seems that the GHSR has managed to protect its hospital-based microbial ecology. However, community germs showed increasing resistance, probably because of an increasing antibiotic pressure, but with resistance rates often inferior to Metropolitan French ones.
