Abstract
Bacterial resistance remains a major concern. Recently, genetic transfers from saprophytic, non-pathogenic, species to pathogenic S. pneumoniae and N. meningitidis have introduced multiple changes in the penicillin target molecules, leading to rapidly growing penicillin resistance. In enterobacteriaceae, a succession of minute mutations has generated new β-lactamases with increasingly expanded spectrum, now covering practically all available β-lactam antibiotics. Resistance emerges in the hospital environment but also, and increasingly, in the community bacteria. Widespread resistance is probably associated with antibiotic use, abuse and misuse but direct causality links are difficult to establish. In some countries as in some hospitals, unusual resistance profiles seem to correspond to unusual antibiotic practices. For meeting the resistance challenge, no simple solutions are available, but combined efforts may help. For improving the situation, the following methods can be proposed. At the world level, a better definition of appropriate antibiotic policies should be sought, together with strong education programmes on the use of antibiotics and the control of cross-infections, plus controls on the strategies used by pharmaceutical companies for promoting antibiotics. At various local levels, accurate guidelines should be adapted to each institution and there should be regularly updated formularies using scientific, and not only economic, criteria; molecular technologies for detecting subtle epidemic variations and emergence of new genes should be developed and regular information on the resistance profiles should be available to all physicians involved in the prevention and therapy of infection.
