In vitro activities of enoxacin, enrofloxacin, sparfloxacin, and ciprofloxacin against Escherichia coli strains isolated from diarrheic lambs and kids.

abstract：:Using the techniques of gap misrepair mutagenesis and site-directed mutagenesis, we have generated two novel quinolone resistance mutations of the Escherichia coli DNA gyrase A protein. DNA sequencing showed these mutations to be Ser-83----Ala and Gln-106----Arg. The mutant proteins were overproduced and purified, and...
