Gallium β‐Cyclodextrin Nanoparticles Containing both Gallium Protoporphyrin and Gallium Nitrate Exhibit Antimicrobial Activity against Nontuberculous Mycobacteria in Vitro and in Vivo

Advanced Therapeutics, EarlyView.
Cyclodextrin nanoparticle containing both Ga(NO3)3 and GaPP is synthesized and tested against non‐tuberculous mycobacteria (NTM). The in vivo efficacy of the nanoparticle therapy is additionally tested by treating pulmonary NTM infections in mice and observed much greater effectiveness in bacterial clearance and survival of mice.

Klebsiella pneumoniae pneumonia

Heart & Lung, 1997
Klebsiella pneumoniae is an uncommon cause of community-acquired pneumonia except in alcoholics. Klebsiella may mimic pulmonary reactivation tuberculosis because it presents with hemoptysis and cavitating lesions. Klebsiella pneumoniae is a difficult infection to treat because of the organism's thick capsule.

The Gut Resistome Atlas in Preterm Infants Enables Prediction of Necrotizing Enterocolitis Onset

Advanced Science, EarlyView.
The gut resistome of preterm infants and its clinical relevance remain poorly understood. This study performs in‐depth integrative analyses of 5,684 gut metagenomes from preterm infants, uncovering distinct features that diverge from term infants. Notably, the gut resistome of preterm infants converges 9 days before necrotizing enterocolitis onset ...

Infections Complicating Orthotopic Liver Transplantation: A Study Emphasizing Graft-Related Septicemia [PDF]

, 1976
In 93 recipients of 102 orthotopic liver homografts, the incidence of bacteremia or fungemia exceeded 70%. The graft itself was usually an entry site for systemic infection after both immunologic and nonimmunologic parenchymal injury, especially if there

Biosynthesis of H2S and Siderophores Targeting Gram‐Negative Bacterial Resistance to Reactive Oxygen Species

Advanced Science, EarlyView.
Discover how Gram‐negative bacteria develop resistance to reactive oxygen species, and how scientists aim to overcome this challenge. Abstract Reactive oxygen species (ROS) are a promising alternative bactericide. However, it is questioned that bacteria can potentially develop resistance to ROS, similar to their resistance against antibiotics and ...
