Activation of lung macrophage nitric oxide synthase-3 improves both bacterial clearance and outcome in primary and secondary pneumonia models.

Being able to take up DNA from their environment might allow pneumococcal bacteria to colonize the human nose and throat for longer periods of time.

Dispensable loops shield the functionally-important extracellular loops of the essential Gram-negative bacterial outer membrane protein LptD from antibody interference.

Internal dynamics play a crucial functional role in MarR (multiple antibiotic resistance repressor) proteins and their role reconciles the distinct allosteric mechanisms proposed previously.

Sequence changes in the pneumococcal genome explain most of the variability in duration of asymptomatic carriage with serotype, antibiotic resistance and prophage accounting for the largest effects.

Penicillin induces bacterial cell lysis by altering cell surface polymer biogenesis to cause the misactivation of a cell wall degrading enzyme.

To avoid recognition by the immune system, bacteria use autolysins to trim fragments of peptidoglycans that are exposed on the bacterial cell wall.

The burden of antimicrobial resistance in Thailand is deteriorating over time, and 19,122 deaths in the country in 2010 were excess deaths caused by multidrug-resistant bacterial infection.

Bacterial-encoded covalent adhesion is a new molecular principle in host-microbe interactions and may play a key role in host colonization by a wide range of Gram-positive bacteria.
