Colonisation with resistant Klebsiella pneumoniae in a Cambodian neonatal unit is driven by person-to-person transmission, transmissibility varies by sequence type, and antibiotic consumption generally increases the risk of acquisition.

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

Nationally-representative verbal autopsies can be linked to seasonal patterns, clinical syndromes, and climate regions to describe novel insights regarding the microbiologic etiologies of childhood pneumonia and diarrhea in India.

SKAP2 is critical for hematopoietic cell protection against Klebsiella infection in mouse lungs, for full phosphorylation of Src Family Kinases, Syk, and Pyk2, and for Klebsiella-induced reactive oxygen species production.

Post-acute or long-COVID is associated with bystander T-cell activation and a recurring antimicrobial resistant, bacterial ventilator-associated pneumonia.

Panproteome array analysis of antibody responses to a pneumococcal whole cell vaccine reveals consistent induction of immune responses to multiple surface proteins, despite individuals' unique pre-existing antibody profiles.

Tracking fluorescent fusion proteins in competent pneumococcal cells reveals a polar hub for competence regulation, with the alternative sigma factor σX relocalizing DprA to this hub to mediate competence shut-off.

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.

A respiratory tissue-associated commensal Lactobacillus strain confers colonization resistance to Streptococcus pneumoniae, when applied therapeutically in a post influenza virus super-infection model.

DNA uptake and recombination in pneumococcus are highly efficient and independent of the cell-cycle or genetic location of the transformed allele, but limited to maximally 50% of the population.
