Combinatorial strategies for improving multiple-stress resistance in industrially relevant Escherichia coli strains.

abstract：:Vibrio cholerae non-O1/non-O139 strains have caused several cases of ear, wound, and blood infections, including one lethal case of septicemia in Austria, during recent years. All of these cases had a history of local recreational activities in the large eastern Austrian lake Neusiedler See. Thus, a monitoring program...
