Direct detection of Listeria monocytogenes in 25 milliliters of raw milk by a two-step PCR with nested primers.

abstract：:The role of Escherichia coli as a pathogen has been the focus of considerable study, while much less is known about it as a commensal and how it adapts to and colonizes different environmental niches within the mammalian gut. In this study, we characterize Escherichia coli organisms (n = 146) isolated from different r...
