Biofilm formation by asymptomatic and virulent urinary tract infectious Escherichia coli strains.

abstract：:We have observed significant cell lysis upon temperature up-shift of recombinant Escherichia coli cultures harboring CI857-repressed lambda-based expression vectors. This event, that becomes evident about 30-40 min after the heat shock, takes place when using the lambda promoter system in Ind- lysogenic strains, but n...
