The emergence of disease caused by penicillin-resistant and
multidrug-resistant pneumococci has become a global concern,
necessitating the identification of the epidemiological spread of such
strains. The Pneumococcal Molecular Epidemiology Network was
established in 1997 under the auspices of the International Union of
Microbiological Societies with the aim of characterizing,
standardizing, naming, and classifying antimicrobial agent-resistant
pneumococcal clones. Here we describe the nomenclature for 16 pneumococcal clones that have contributed to the increase in
antimicrobial resistance worldwide. Guidelines for the recognition of
these clones using molecular typing procedures (pulsed-field gel
electrophoresis, BOX-PCR, and multilocus sequence typing) are
presented, as are the penicillin-binding profiles and macrolide
resistance determinants for the 16 clones. This network can serve as a
prototype for the collaboration of scientists in identifying clones of
important human pathogens and as a model for the development of other networks.
