Variant B. anthracis
satA alleles confer impaired streptothricin resistance to S. enterica. Strains carrying wild-type alleles (B. anthracis
satA+, open circles), variant B. anthracis
satA alleles, or empty vector (open squares) were grown in glycerol (22 mM) minimal medium and challenged with 5 μM streptothricin (columns E and F) or 10 μM streptothricin (columns G and H) with either 250 μM l-(+)-arabinose (columns E and G) or 500 μM l-(+)-arabinose (columns F and H) for induction. Error bars represent standard deviations. Symbols shown refer to growth curves on that row. All strains carried chromosomal ΔmetE2702 ara-9 mutations and carried the indicated plasmids: JE22263 (/pCV1; squares), JE24022 (/pBaSAT1; circles), JE24312 (/pBaSAT3; triangles), JE24313 (/pBaSAT4; inverted triangles), JE24456 (/pBaSAT12; diamonds), JE24457 (/pBaSAT13; asterisks), JE24586 (/pBaSAT20; stars), JE24314 (/pBaSAT5; triangles), JE24458 (/pBaSAT14; inverted triangles), JE24459 (/pBaSAT15; diamonds), JE24315 (/pBaSAT6; asterisks), JE24460 (/pBaSAT16; stars), JE24461 (/pBaSAT17; triangles), JE24316 (/pBaSAT7; inverted triangles), JE24317 (/pBaSAT8; diamonds), JE24588 (/pBaSAT21; asterisks), JE24318 (/pBaSAT9; triangles), JE24319 (/pBaSAT10; inverted triangles), JE24462 (/pBaSAT18; diamonds), JE24463 (/pBaSAT19; asterisks), and JE24320 (/pBaSAT11; stars). vector, pCV1 (27).
