The fate of verocytotoxigenic Escherichia coli C600 phi 3538(vtx(2)::cat) and its vtx(2) prophage during grass silage preparation

摘要

AimsSilage is grass, preserved by fermentation and used as winter feed for cattle. The impact of a range of current grass silage preparation practices on the survival of Escherichia coli C6003538(vtx(2)::cat) and on the induction, release and infectivity of free phage were investigated.
