S. enterica serovar Typhimurium LT2 SL4213 and E. coli K-12 W3110 harboring pKK661 and one of seven pKK641 series plasmids were used as donor strains. S. enterica serovar Typhimurium LT2 and E. coli K-12 with and without various waa+ plasmids were used as recipient strains. Liquid matings were carried out at 37°C for 1.5 h. For each recipient strain, the ratio of the frequency of transfer of pKK661 from E. coli K-12 or serovar Typhimurium LT2 donor cells expressing various PilV adhesins to the highest transfer frequency (1.0) is estimated. High ratios are indicated by boldface type.
+, sensitive; ±, partially sensitive; −, resistant.
