Here's my 2 scents worth....in Salmonella typhimurium srl::tn10dTet is
often used as a closely linked marker for the transduction of recA1
(approx. %12). When TetR cannot be used people often try srl::Tn10dCam.
There are also strains (both E.coli and S.typhimurium) which has a
Kanamycin cassette inactivating recA. You can do P1 transductions between
S.typhimurium and E.coli (with a commensurate reduction in efficiency)
I hope some of the above core dump is useful
