Antimicrobial drug resistance genes do not convey a secondary fitness advantage to calf-adapted Escherichia coli
Article Abstract:
A study was conducted on the effect of antimicrobial drug resistance genes on Escherichia coli. It was observed that the greater fitness advantage of anti-microbial-resistant Escherichia coli in calves is in no way affected by the antimicrobial resistance genes, but the farm environment and the diet are clearly responsible for the maintenance of the microbial resistance genes.

Multiple environmental stress tests show no common phenotypes shared among contemporary epidemic strains of Salmonella enterica
Article Abstract:
The comparison of phenotypic traits of coexisting epidemic and nonepidemic strains of Salmonella enterica serovars Typhimurium and Newport identified specific upregulated genes during defined stress conditions but no common traits were shared by epidemic serovars.
