Correlation of β-Lactamase Production and Colistin Resistance among Enterobacteriaceae Isolates from a Global Surveillance Program.

abstract：:The multidrug resistance profiles of Klebsiella pneumoniae carbapenemase (KPC) producers have led to increased clinical polymyxin use. Combination therapy with polymyxins may improve treatment outcomes, but it is uncertain which combinations are most effective. Clinical successes with intravenous minocycline-based com...
