Pyruvate formate lyase is required for pneumococcal fermentative metabolism and virulence.

open access: yes, 2009
Knowledge of the in vivo physiology and metabolism of Streptococcus pneumoniae is limited, even though pneumococci rely on efficient acquisition and metabolism of the host nutrients for growth and survival.

Lactate Signal: Modulator of Cellular Energy Production and Anabolism

open access: yesAdvanced Science, EarlyView.
Compartmentalized lactate signaling provides a spatial framework for understanding how lactate‐rich states are generated, transported, sensed, and translated into biological outputs. This Review integrates extracellular, cytosolic, mitochondrial‐associated, and nuclear lactate mechanisms to explain how lactate shapes metabolic adaptation, immune ...

pH‐Driven Two‐Stage Conformational Switching Activates an Acid‐Responsive Chaperone

open access: yesAngewandte Chemie, EarlyView.
AchC is an ATP‐independent, pH‐responsive chaperone. AchC functions as a molecular switch, sensing pH changes and undergoing a two‐stage conformational transition: C‐terminal extension (colored in yellow) loosening at mild pH 4.0–5.5 and monomerization at strong acidic pH 3.0.

Extended-spectrum beta-lactamase (ESBL) production and virulence genes profile of avian pathogenic Escherichia coli (APEC) isolated from broiler chickens in eastern Thailand

open access: yesVeterinary Integrative Sciences
Avian pathogenic Escherichia coli (APEC) causes colibacillosis, resulting in extensive economic losses for the broiler industry. To date, there is little information in Thailand about virulence-associated genes and antibiotic resistance of APEC ...

Analysis of Additional Virulence Genes and Virulence Gene Regions in Listeria monocytogenes Confirms the Epidemiologic Relevance of Multi-Virulence-Locus Sequence Typing

open access: yesJournal of Food Protection, 2008
Previous molecular subtyping studies have defined four epidemic clones (ECs) of Listeria monocytogenes (ECI, ECII, ECIII, and ECIV). Partial sequences of eight virulence genes were previously shown to be identical within individual ECs of L. monocytogenes.

The Interplay Between Molybdopterin Synthase and Metal Metabolism Contributes to Pathogenicity in Acinetobacter baumannii

open access: yesAdvanced Science, EarlyView.
Pathogenic Acinetobacter baumannii scavenges metal ions as nutritional elements to survive within the host. This study demonstrates that molybdopterin synthase is essential for pathogenesis and full virulence during infection. Molybdopterin synthase subunit MoaE constitutes an intrinsically disordered C‐terminal histidine rich tail, which mediates ...

Magnetic Resonance Reveals Radical Stability in Native Biofilms and Its Role in Bacterial Resistance

open access: yesAngewandte Chemie, EarlyView.
The complex biofilm environment consists of planktonic bacterial cells and cells embedded in an extracellular matrix (ECM). Through an integrated magnetic resonance approach, we show that nitroxide radicals primarily interact with the polysaccharides and lipids in the ECM.

Carbapenem-resistant Pseudomonas aeruginosa T3SS virulence genes and correlation between virulence and drug resistance and molecular epidemiology studies

open access: yesFrontiers in Pharmacology
ObjectiveThis study aimed to investigate the relationship between the carriage and expression of virulence genes associated with the type III secretion system (T3SS) in carbapenem-resistant Pseudomonas aeruginosa (CRPA) and their impact on virulence ...

The Collective Power of Bacteria as a Blueprint for Emergent Intelligence

open access: yesAdvanced Intelligent Systems, EarlyView.
Small cells, powerful collectives. Bacteria demonstrate how sophisticated behaviors can emerge from many simple individuals working together. We explore the remarkable world of bacterial communities and the mechanisms that underpin their complex emergent behaviors, enabling impressive adaptability, robustness, and responsiveness to changing ...

Synthetic Particulate Subunit Vaccines Co‐Delivering Multiple Antigens Induce Protective Immunity Against Melioidosis

open access: yesAdvanced NanoBiomed Research, EarlyView.
Engineered endotoxin‐free Escherichia coli were used to assemble poly(3‐hydroxybutyrate) (PHB) biopolymer particles displaying multiple conserved Burkholderia pseudomallei antigens via PhaC‐mediated surface presentation. Following formulation with poly(I:C), the particulate vaccines induced antigen‐specific humoral and cellular immune responses ...
