Background: SMART (Study for Monitoring Antimicrobial Resistance Trends) is an ongoing global antimicrobial surveillance programme focused on clinical isolates from intraabdominal infections (IAI). The 2005 analysis assessed antimicrobial susceptibility patterns among inducible Enterobacteriaceae from Europe.
Methods: 25 European sites tested the in vitro activity of 12 antimicrobial agents. Microdilution techniques followed CLSI guidelines. All Enterobacter, Serratia, Citrobacter, Providencia spp., Morganella morganii, Hafnia alvei, & Proteus vulgaris were considered to have inducible b-lactamases for this study.
Results: Inducible Enterobacteriaceae were recovered from 19% of pts (347/1820); 18% (350/1964) of the total isolates. 42% (145) of these isolates were recovered <48 hrs of hospitalisation. Enterobacter spp. (46%), Citrobacter spp. (25%), M. morganii (12%) & Serratia spp. (6%) were the most common isolates. Susceptibility rates are listed in the table.
Conclusion: The majority of isolates were recorded >48 hrs of hospitalisation. Enterobacter species were the most common isolates. Cefoxitin & ampicillin-sulbactam were the least active agents; ertapenem, imipenem & amikacin were the most active agents in vitro.
