A total of 380 pseudomonad strains from 39 nomenspecies and 41 strains from 7 other bacterial genera were screened for a double-stranded ribonucleic acid modification and restriction system using the double-stranded ribonucleic acid bacteriophage φ{symbol}6. Of these 421 strains, 8 showed the low plating efficiency (10-5 to 10-7) characteristic of such a system. Howver, the phage propagated in 7 of the 8 were host-range mutants; the remaining strain showed some characteristics of a host-modification system but the results were equivocal.
