Increased loss of duplicated genes in streptomycin-resistant (strA) mutants of Escherichia coli k-12.
نویسندگان
چکیده
The recombination-dependent loss of a duplicated portion of the Escherichia coli chromosome is five- to tenfold greater in strains containing streptomycin resistance (strA) mutations than in the strA+ parental strain. Streptomycin (500 mug/ml) partially reverses the increase. These results suggest an interaction between strA mutations and recombination.

Expression of tolC and organic solvent tolerance of Escherichia coli ciprofloxacin resistant mutants
AcrAB-TolC is a major efflux pump in Escherichia coli. It was reported that tolC is overexpressed and involves in improving the organic solvent tolerance level in Escherichia coli marR mutants that are resistant to several antibiotics, such as ciprofloxacin. Low and intermediate levels resistance did not improve organic solvent tolerance. Thus, in this descriptive-experimental study it was deci...
متن کاملStudy of Mutations in the DNA gyrase gyrA Gene of Escherichia coli
Quinolones are a large and widely consumed class of synthetic drugs. Expanded-spectrum quinolones, like ciprofloxacin are highly effective against Gram-negative bacteria, especially Escherichia coli. In E. coli the major target for quinolones is DNA gyrase. This enzyme is composed of two subunits, GyrA and GyrB encoding by gyrA and gyrB, respectively. Mutations in either of these genes cause qu...

متن کاملDevelopment of auxotrophy by streptomycin-resistant mutation.
Several streptomycin-resistant mutants of Escherichia coli have been isolated which require exogenous isoleucine for growth. The majority of these strains were of streptomycin-dependent phenotype. If grown in the absence of streptomycin, these streptomycin-dependent auxotrophs (Sm(d-aux)) strains were unable to produce beta-galactosidase and aldolase activities and also failed to exhibit donor ...
