BlaCMY-2 positive Inc A/C plasmids from Escherichia coli and Salmonella enterica are a distinct component of a larger lineage of plasmids

Call, Douglas R.; Singer, Randall S.; Meng, Da; Broschat, Shira L.; Orfe, Lisa H.; Anderson, Janet M.; Herndon, David R.; Kappmeyer, Lowell S.; Daniels, Joshua B.; Besser, Thomas E (Antimicrobial Agents and Chemotherapy, 2009-11)

Large multidrug resistance plasmids of the A/C incompatibility complex (IncA/C) have been found in a diverse group of Gram-negative commensal and pathogenic bacteria. We present three completed sequences from IncA/C plasmids ...

Genotypic-phenotypic discrepancies between antibiotic resistance characteristics of Escherichia coli from calves in high and low antibiotic use management settings

Davis, Margaret A.; Besser, Thomas E.; Orfe, Lisa H.; Baker, Katherine N. K.; Lanier, Amelia S.; Broschat, Shira L.; New, Daniel; Call, Douglas R (Applied and Environmental Microbiology, 2011-05)

We hypothesized that bacterial populations growing in the absence of antibiotics will accumulate more resistance gene mutations than bacterial populations growing in the presence of antibiotics. If this is so, the prevalence ...
