conclusions: e. coli herb-resistance plasmid can replicate and be expressed in s. aureus. results: the identified 45 kb herb-resistance plasmid could be transferred from e. coli cp9 isolates to e. coli dh5α. as a consequence e. coli dh5α transconjugant mic increased from 0.0125 g/ml to 0.25 g/ml. the plasmid was easily transferred from e. coli cp9 strain to s. aureus rn450rf with a mean transfe...

Objective(s): Chemotherapies used to treat colon cancer might often fail due to the emergence of chemoresistance and side effects. Escherichia coli Nissle 1917 (EcN) is a beneficial probiotic, whose molecular mechanisms in the prevention of colon cancer are yet to be fully understood. The present study assessed the anti-cancer effects of EcN treatments in human colorec...
