Human alveolar lining fl uid from the elderly promotes Mycobacterium tuberculosis intracellular growth and translocation into the cytosol of alveolar epithelial cells

Vivek Vijay Thacker, Richa Mishra

The elderly population is highly susceptible to developing respiratory diseases, including tuberculosis, a devastating disease caused by the airborne pathogen Mycobacterium tuberculosis ( M.tb ) that kills one person every 18 seconds. Once M.tb reaches the ...

A Rapidly Responsive Sensor for Wireless Detection of Early and Mature Microbial Biofilms

Hubert Girault, Andreas Stephan Lesch, Bhawna Nagar, Wanderson Oliveira Da Silva

Biofilm-associated infections, which are able to resist antibiotics, pose a significant challenge in clinical treatments. Such infections have been linked to various medical conditions, including chronic wounds and implant-associated infections, making the ...

Engineering Agrobacterium tumefaciens Adhesion to Target Cells

Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Zaïnebe Dhirani, Jeremy Pak Hei Wong, Alix Kim Lan Pham

Agrobacterium tumefaciens is a plant pathogen commonly repurposed for genetic modification of crops. Despite its versatility, it remains inefficient at transferring DNA to many hosts, including to animal cells. Like many pathogens, physical contact between ...

Structural Basis of Ligand Selectivity by a Bacterial Adhesin Lectin Involved in Multispecies Biofilm Formation

Corey Alfred Stevens

Carbohydrate recognition by lectins governs critical host-microbe interactions. MpPA14 (Marinomonas primoryensis PA14 domain) lectin is a domain of a 1.5-MDa adhesin responsible for a symbiotic bacterium-diatom interaction in Antarctica. Here, we show that ...

Loss of Bacterial Cell Pole Stabilization in Caulobacter crescentus Sensitizes to Outer Membrane Stress and Peptidoglycan-Directed Antibiotics

Gerardo Turcatti, Marc Chambon, Julien Bortoli Chapalay

Rod-shaped bacteria frequently localize proteins to one or both cellpoles in order to regulate processes such as chromosome replication or polar organ-elle development. However, the roles of polar factors in responses to extracellularstimuli have been gene ...

Advanced Quantification Methods To Improve the 18b Dormancy Model for Assessing the Activity of Tuberculosis Drugs In Vitro

Stewart Cole, Claudia Sala

One of the reasons for the lengthy tuberculosis (TB) treatment is the difficulty to treat the nonmultiplying mycobacterial subpopulation. In order to assess the ability of (new) TB drugs to target this subpopulation, we need to incorporate dormancy models ...

Yeast Nanometric Scale Oscillations Highlights Fibronectin Induced Changes in C. albicans

Giovanni Dietler, Sandor Kasas, Leonardo Venturelli, Anne-Céline Verenna Kohler

Yeast resistance to antifungal drugs is a major public health issue. Fungal adhesion onto the host mucosal surface is still a partially unknown phenomenon that is modulated by several actors among which fibronectin plays an important role. Targeting the ye ...

Mycobacterium tuberculosis Resists Stress by Regulating PE19 Expression

John McKinney, Anna De Graff Tischler

Mycobacterium tuberculosis requires the phosphate-sensing signal transduction system Pst/SenX3-RegX3 to resist host immune responses. A Delta pstA1 mutant lacking a Pst phosphate uptake system component is hypersensitive to diverse stress conditions in vit ...

Identification of airway bacterial colonization by an electronic nose in Chronic Obstructive Pulmonary Disease

Background: Airway bacterial colonization by potentially pathogenic microorganisms occurs in a proportion of patients with Chronic Obstructive Pulmonary Disease (COPD). It increases airway inflammation and influences outcomes negatively. Yet, its diagnosis ...

Regulatory elements involved in the expression of competence genes in naturally transformable Vibrio cholerae

Melanie Blokesch, Mirella Lo Scrudato

BackgroundThe human pathogen Vibrio cholerae normally enters the developmental program of natural competence for transformation after colonizing chitinous surfaces. Natural competence is regulated by at least three pathways in this organism: chitin sensing ...

A Multivalent Adsorption Apparatus Explains the Broad Host Range of Phage phi92: a Comprehensive Genomic and Structural Analysis

Petr Leiman, Sergey Nazarov, Christopher Browning

Bacteriophage phi92 is a large, lytic myovirus isolated in 1983 from pathogenic Escherichia coli strains that carry a polysialic acid capsule. Here we report the genome organization of phi92, the cryoelectron microscopy reconstruction of its virion, and th ...

Quorum Sensing Contributes to Natural Transformation of Vibrio cholerae in a Species-Specific Manner

Melanie Blokesch, Patrick Martin Seitz

Although it is a human pathogen, Vibrio cholerae is a regular member of aquatic habitats, such as coastal regions and estuaries. Within these environments, V. cholerae often takes advantage of the abundance of zooplankton and their chitinous molts as a nut ...

Haloalkane Dehalogenase LinB is responsible for β- and δ-hexachlorocyclohexane transoformation in sphingobium indicum B90A

Christof Holliger

Incubation of resting cells of Sphingobium indicum B90A, Sphingobium japonicum UT26, and Sphingobium francense Sp+ showed that they were able to transform ß- and -hexachlorocyclohexane (ß- and -HCH, respectively), the most recalcitrant hexachlorocyclohexan ...
