Adaptive mutation mechanism may drive some forms of antibiotic resistance

August 27th, 2015 (No Comments)

Retromutagenesis resolves the puzzle: if cells aren’t growing because they’re under stress, which means their DNA isn’t being copied, how do the new mutants appear?
The answer: a mutation appears in the RNA first. Despite its name, retromutagenesis does not involve reverse transcriptase.

Antibiotic resistance enzyme caught in the act

ICYMI, part of an increasing interest in antibiotic resistance at Emory, coming from many angles: biochemistry/microbiology/infectious diseases.

Retaining the resistance: MCR-1, colistin + lysozyme

October 18th, 2016 (No Comments)

The plasmid MCR-1, which confers resistance to the last-resort antibiotic colistin, also confers resistance to an antimicrobial enzyme produced by our bodies. This suggests that the pressure of fighting the host immune system may select for MCR-1 to stick around, even in the absence of colistin use.
