| Abstract: | The exclusion relationship between the IncI plasmids R144, R64 and ColIb was studied in such a way that incompatibility interference was avoided. Genetic crosses with an R144-derived Hfr donor, crosses with recipient strains carrying R144-derived exclusion genes on a recombinant plasmid compatible with R144, and measurement of transmission frequencies of a recombinant plasmid compatible with IncI plasmids after mobilization by R144 revealed that R144, R64 and ColIb belong to one exclusion group. |
