Research Article: Chromosome-Mediated Colistin Resistance in Clinical Isolates of Klebsiella pneumoniae and Escherichia coli: Mutation Analysis in the Light of Genetic Background
Introduction:
The increasing prevalence of multidrug-resistant Gram-negative bacteria, together with the lack of new antibiotics has led to the reintroduction of disused drugs such as colistin. For many years this antibiotic was used only as a topical treatment in human medicine, because of its nephrotoxicity.
