title: [Intergeneric conjugational hybridization of Escherichia coli and Salmonella typhimurium. 1. Obtaining a salmonella hybrid possessing greater recipient activity in crosses with Escherichia coli].
abstract: Intergeneric hybrids were selected from mating HfrH Escherichia coli with F- Salmonella typhimurium. The hybrid obtained from E. coli leu+ and pro+ genes possessed the increased recipient ability in the mating with E. coli HfrR1 (O--ilv--metE--ara). This hybrid lacked the ability to restrict the phage P1 DNA propagated on E. coli K-12. The replacement of mutated uvrA gene of Salmonella for uvrA+ gene of E. coli restore uvr+ phenotype of Salmonella mutant.
