Abstract excerpt
Transposon Tn5 mutants of L. pneumophila were isolated and screened for loss of virulence-associated characteristics. Three mutants were found with normal ability to produce putative pathogenicity determinants and to be endocytosed by guinea pig alveolar macrophages in vitro but with a greatly reduced ability to multiply within them. These mutants showed considerable loss of virulence in an authentic animal model...
