AadT, a new weapon in Acinetobacters fight against antibiotics

V. N. Naidu, B. Shah, C. Maher, I. T. Paulsen, K. A. Hassan

The paper identifies AadT, a new multidrug efflux pump in Acinetobacter, which reduces susceptibility to multiple antimicrobials and is associated with resistance genes.

Characterising the mechanism of action of an ancient antimicrobial, honey, using modern transcriptomics

D. Bouzo, N. N. Cokcetin, L. Li, G. Ballerin, A. L. Bottomley, J. Lazenby, C. B. Whitchurch, I. T. Paulsen, K. A. Hassan, E. J. Harry

This study uses transcriptomics to show that manuka honey's antimicrobial action involves multiple mechanisms, including SOS response, oxidative damage, and membrane disruption, without promoting bacterial resistance.
