N1 - Of eight Salmonella, serB-linked hsd genes for the restriction and modification of DNA transferred to Escherichia coli/Salmonella hybrids, only two--those with SM and ST (S. muenchen and S. thompson, respectively) specificities--may have weakly complemented rSB- and none complemented rK-. An A-specific DNA probe failed to hybridize to HindIII-restricted fragments of each of the hybrids, but an SB (S.

An A-specific DNA probe failed to hybridize to HindIII-restricted fragments of each of the hybrids, but an SB (S. typhimurium)-specific probe hybridized to DNA from the hybrid with ST specificity. These results indicate that additional families of the type I hsd genes may exist.
