The production of fimbriate (Fim+) recombinants was observed in transductional crosses between different pairs of wild-type strains of different biotypes of Salmonella typhimurium. Fim+ recombinants were readily produced in transductions from Fim+ donor strains to Fim- recipient strains and, less frequently, between some pairs of Fim- strains, for example, between almost any strain of the firn biogroup (Fim- Inl- Rha- Bxyl-) and many strains of the non-FIRN Fim- biogroup. None of numerous crosses between different pairs of FIRN strains gave Fim+ recombinants, suggesting that the fim mutation was present at the same intragenic site in all FIRN strains. FIRN strains are thought to have descended from a single ancestral FIRN bacterium which originated by a series of mutations from a strain of the common biotype 1a (Fim+ Inl+ Rha+ Bxyl+). Two FIRN-like (Fim- Inl+ Rha- Bxyl-) strains that did not yield Fim+ recombinants in crosses with FIRN strains were probably wild-type Inl+ mutants from FIRN strains.
