Figure 1From: A multicopy suppressor screening approach as a means to identify antibiotic resistance determinant candidates in Yersinia pestisReduction of ofloxacin susceptibility conferred by plasmids pGEM-OFXr1 and pGEM-Rob Yp . E. coli (Ec) and Y. pestis (Yp) strains were streaked on solid media without or with ofloxacin: 0.35 μg/ml (the concentration used in the screen) for E. coli and 0.15 μg/ml for Y. pestis. Ampicillin (100 μg/ml) was also added to the media for plasmid-carrying strains.Back to article page
