Abstract

SUMMARY: R-1818 increases swarming and abolishes proteolytic enzyme excretion by F67. R-TEM reduces swarming, increases proteolytic enzyme excretion by this organism and renders it susceptible to sodium deoxycholate. The properties of strains harbouring both R-1818 and R-TEM simultaneously are dependent on the order of introduction of the R factors, the R factor first present being dominant. Recombination between the R factors in this organism does not seem to be responsible for these observations.
