Bacterial Cell Surface Deformation under External Loading [PDF]

mBio, 2012
ABSTRACTViscoelastic deformation of the contact volume between adhering bacteria and substratum surfaces plays a role in their adhesion and detachment. Currently, there are no deformation models that account for the heterogeneous structure and composition of bacteria, consisting of a relatively soft outer layer and a more rigid, hard core enveloped by ...

Quantification of Bacterial Loads in Caenorhabditis elegans

BIO-PROTOCOL, 2022
Caenorhabditis elegans is a ubiquitous free-living nematode that feeds on bacteria. The organism was introduced into a laboratory setting in the 1970s and has since gained popularity as a model to study host-bacteria interactions. One advantage of using C. elegans is that its intestine can be colonized by the bacteria on which it feeds. Quantifying the

A Tuberculosis Molecular Bacterial Load Assay (TB-MBLA) [PDF]

Journal of Visualized Experiments, 2020
Tuberculosis is caused by Mycobacterium tuberculosis (Mtb), a pathogen classified by the United Nations (UN) as a dangerous category B biological substance. For the sake of the workers' safety, handling of all samples presumed to carry Mtb must be conducted in a containment level (CL) 3 laboratory.

Exposing the small protein load of bacterial life

FEMS Microbiology Reviews, 2023
Abstract The ever-growing repertoire of genomic techniques continues to expand our understanding of the true diversity and richness of prokaryotic genomes. Riboproteogenomics laid the foundation for dynamic studies of previously overlooked genomic elements.

Load-Dependent Assembly of the Bacterial Flagellar Motor [PDF]

mBio, 2013
ABSTRACT It is becoming clear that the bacterial flagellar motor output is important not only for bacterial locomotion but also for mediating the transition from liquid to surface living. The output of the flagellar motor changes with the mechanical load placed on it by the external environment: at a higher load, the motor runs more slowly ...

Tuberculosis Molecular Bacterial Load Assay Reveals Early Delayed Bacterial Killing in Patients With Relapse [PDF]

Clinical Infectious Diseases, 2022
Abstract Bacterial killing in patients with tuberculosis (TB) relapse was compared to that in patients achieving cure, measured by TB molecular bacterial load assay (TB-MBLA) or mycobacteria growth indicator tube (MGIT) time to positivity (TTP).

Load-dependent adaptation near zero load in the bacterial flagellar motor [PDF]

Journal of The Royal Society Interface, 2019
The bacterial flagellar motor is an ion-powered transmembrane protein complex which drives swimming in many bacterial species. The motor consists of a cytoplasmic ‘rotor’ ring and a number of ‘stator’ units, which are bound to the cell wall of the bacterium. Recently, it has been shown that the number of functional torque-generating stator units in the

Physicochemical and microbiological analyses of bacterial isolates from drinking water distribution systems of some higher institutions in Edo State, Nigeria

Journal of Applied Sciences and Environmental Management, 2019
In drinking water systems, a large number of microorganisms live in complex communities in a selfproduced extracellular polymeric matrix associated with inner surfaces of pipes, walls and floors of storage tanks, joints and faucets. This study was aimed

Brain effects of gestating germ-free persist in mouse neonates despite acquisition of a microbiota at birth

Frontiers in Neuroscience, 2023
At birth, mammals experience a massive colonization by microorganisms. We previously reported that newborn mice gestated and born germ-free (GF) have increased microglial labeling and alterations in developmental neuronal cell death in the hippocampus ...
