Certain circular DNA molecules called plasmids that confer antibiotic resistance in bacteria found in meat and poultry also have been discovered in the plague bacillus Yersinia pestis, according to a research team led by investigators at the Institute for Genomic Research, in Rockville, Md (Welch TJ et al.

"This reservoir of mobile resistance determinants has the potential to disseminate to Y pestis and other human and zoonotic bacterial pathogens and therefore represents a significant . . . [Full Text of this Article]
