The Difference

SummaryThe distribution of plasmids was studied in a representative collection of salmonella strains which comprised 98Salmonella typhimuriumand 96 other serotypes. Plasmids were detected in 72% of strains (mean 1·3 plasmids/strain) and individual strains harboured between 0 and 7 plasmids. They were more common amongS. typhimuriumthan other serotypes (incidence 92 and 53%; mean 1·9 and 0·8 plasmids/strain respectively). Although a higher proportion ofS. typhimurium(33%) were antibiotic-resistant compared to other serotypes (14%) the evidence presented indicated that R-plasmids were not responsible for the difference observed in the number and distribution of plasmids in these strains. These results were discussed in comparison with similar studies ofEscherichia coliand other enteric genera.
