Recent advances in the potential interconnection between antimicrobial resistance to biocides and antibiotics

Workshop on biocides: do they select for antimicrobial resistance? Second International Conference on Antimicrobial Research, Lisbon, Portugal, 21–23 November 2012.

Interconnection between microbial resistance to biocides and antibiotics is a topic of increasing interest given the recent changes in European legislation and claims of a risk of biocide use on bacterial resistance. In the second International Conference on Antimicrobial Research held in Lisbon in November 2012, a workshop specifically addressed this topic, presentations included approaches to risk assessment and investigations into the molecular mechanisms of biocide resistance and co- and cross-resistance to antibiotics. The overall conclusion was that, even if each biocide represents a specific case, there is scientific evidence that biocides select for biocide resistance, but that there is, so far, no conclusive evidence that this also determined or will determine an increase in antibiotic resistance.

All main speakers agreed that overuse or micuse of biocides may present a risk for selection of  biocide resistance, and it may be advisable to monitor use of biocides base on the “precaution principle”. Conversely, all speakers agreed that, so far, the extension of the correlation between biocide use and reduced biocide susceptibility cannot be extended to o clinically relevant antibiotic resistance  at present.
