Abstract
Maintenance of pathogenicity of viable but nonculturable Salmonella typhimu rium cells experimentally stressed with UV-C and seawater, was investigated relative to the viability level of the cellular population. Pathogenicity, tested in a mouse model, was lost concomitantly with culturability, wherea s cell viability remained undamaged, as determined by respiratory activity and cytoplasmic membrane and genomic integrities.
