ampC beta-lactamase hyperproduction in Escherichia coli: natural ampicillin resistance generated by horizontal chromosomal DNA transfer from Shigella.
Six ampicillin-resistant clinical isolates of Escherichia coli that hyperproduced the chromosomal ampC beta-lactamase were studied. By DNA sequence analysis, we found that five of them were identical over an entire 449-base-pair sequence and carried a novel strong ampC promoter [Olsson, O., Bergströ...
