To evaluate whether acquired resistance to cationic antimicrobial peptides (CAMP) group molecules, being normal components of the human immune system, may select co-resistance to antibiotic peptides such as polymyxins, considering they share the same mechanism of action. We aimed to evaluate strains producing the recently identified plasmid-encoded polymyxin resistance determinant MCR-1,...

The polymyxin antibiotic colistin is an antibiotic of last resort for the treatment of extensively drug-resistant Gram-negative bacteria, including carbapenemase- producing Enterobacteriaceae. The State of the World’s Antibiotics report in 2015 highlighted South Africa (SA)’s increasing incidence of these ‘superbugs’ (3.2% of Klebsiella pneumoniae reported from SA were carbapenemase...
