Antimicrobial activity of polymyxin A, and characterisation of the cognate biosynthetic gene cluster within the genome of the producing Paenibacillus polymyxa.

Amy McLeman, Alexander D. H. Kingdon, Robin Hoeven, George Taylor, Ellie Allman, Issra Bulgasim, Claudia McKeown, Richard N. Goodman, Sabrina John Moyo, Adam Paul Roberts

This study isolates a Paenibacillus polymyxa strain, characterizes its polymyxin A biosynthetic gene cluster, and finds that resistance genes mcr-1 and mcr-4 confer resistance to polymyxin A.

An evaluation of screening methods for the detection of extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae in environmental samples from healthcare settings

Esther Picton-Barlow, Claudia McKeown, Sally Forrest, Sarah Gallichan, Maria Moore, Nicholas Feasey, Joseph M. Lewis, Fabrice E. Graf

This study evaluates screening methods to detect ESBL-producing E. coli and K. pneumoniae in healthcare environmental samples, finding that 18-hour pre-enrichment and specific selective agar improve detection.
