Spatio-temporal modeling of the crowding conditions and metabolic variability in microbial communities

Vassily Hatzimanikatis, Liliana Angeles Martinez

The metabolic capabilities of the species and the local environment shape the microbial interactions in a community either through the exchange of metabolic products or the competition for the resources. Cells are often arranged in close proximity to each ...

Revealing Antibiotic Tolerance of the Mycobacterium smegmatis Xanthine/Uracil Permease Mutant Using Microfluidics and Single-Cell Analysis

John McKinney, Neeraj Dhar, Meltem Elitas

To reveal rare phenotypes in bacterial populations, conventional microbiology tools should be advanced to generate rapid, quantitative, accurate, and high-throughput data. The main drawbacks of widely used traditional methods for antibiotic studies include ...

Dynamic persistence of UPEC intracellular bacterial communities in a human bladder-chip model of urinary tract infection

Graham Knott, John McKinney, Neeraj Dhar, Vivek Vijay Thacker, François Signorino-Gelo, Kunal Sharma, Thomas Marie Simonet

Uropathogenic Escherichia coli (UPEC) proliferate within superficial bladder umbrella cells to form intracellular bacterial communities (IBCs) during early stages of urinary tract infections. However, the dynamic responses of IBCs to host stresses and anti ...

Antimicrobial susceptibility testing by measuring bacterial oxygen consumption on an integrated platform

Martinus Adela Maria Gijs, Thomas Lehnert

Cellular respiration is a fundamental feature of metabolic activity and oxygen consumption can be considered as a reliable indicator of bacterial aerobic respiration, including for facultative anaerobic bacteria like E. coli. Addressing the emerging global ...

Microtissue models for studying the dynamics of host-pathogen interactions in the urinary bladder

Kunal Sharma

Urinary tract infections (UTIs) are amongst the most common bacterial infections and are the second-most frequent reason for antibiotic prescriptions. Moreover, in about 25% of all treated cases, recurrence of infection occurs. Uropathogenic Escherichia co ...

The Quest for Genes Involved in Adaptation to Climate Change in Ruminant Livestock

Stéphane Joost, Elia Vajana

Simple Summary: After domestication in specific regions, livestock followed human migrations and colonized the whole world. During this population expansion, human and natural selection, together with demographic events, molded the livestock genome leading ...

Scratching the Surface: Bacterial Cell Envelopes at the Nanoscale

Georg Fantner

The bacterial cell envelope is essential for viability, the environmental gatekeeper and first line of defense against external stresses. For most bacteria, the envelope biosynthesis is also the site of action of some of the most important groups of antibi ...
