This complementary scheme of phage-typing is based on the use of 15 new phages from sewage; 39 phage-types were found among a group of the non-tvpable strains isolated in several hospitals in Lisbonne. The relations between the serotypes, the pyocinotypes and the new liysotypes are investigated.Environ 20% des souches de Pseudomonas aeruginosa isolées au Portugal ne sont pas typables par le système de lysotypie de Lindberg. Grâce à un système de lysotypie complémentaire comportant 15 nouveaux bactériophages, il a été possible de typer la majorité de ces souches.fraPseudomonas aeruginosaPhage typingSerotypingEpidemiologyPortugalLysotypieSérotypieÉpidémiologiejournal article
