Sensitivity of the genetic transfer system of F-like plasmid pAP42 marked with the transposons Tn1 and TN9 to fertility inhibitors of six reference Fin-groups was studied. It was shown that transfer function and donor-specific piliformation of the plasmid under study were inhibited by reference plasmids of FinU and FinV groups, surface exclusion by plasmids of FinU and FinQ groups. The different influence of the FinOP group plasmid on transfer functions of the marked plasmids pAP42::Tn1 and pAP42::Tn9 that is likely to be connected with the effect of incorporated transposons was determined.
