Mechanically-driven spreading of bacterial populations [PDF]

Commun. Nonlinear Sci. Numer. Simulat. 35, 88 (2016), 2015
The effect of mechanical interactions between cells in the spreading of bacterial populations was investigated in one-dimensional space. A continuum-mechanics approach, comprising cell migration, proliferation, and exclusion processes, was employed to elucidate the dynamics.

Assessment of Factors Contributing to Infection Severity and High Levels of Drug Resistance in Clinical Enterococcus Isolates

Journal of Clinical Laboratory Analysis, EarlyView.
E. faecalis was the predominant species (60.7%). Moreover, 39.3% of the isolates were identified as VRE with an MIC > 32 μg/mL, and the vanA gene was detected in 35.7% of the isolates. High‐level resistance to gentamicin and streptomycin was observed in 60.7% and 50% of the isolates, respectively.

Aspergillus fumigatus endocarditis in a splenectomized patient with no risk factors

IDCases, 2020
Aspergillus endocarditis is a rare cause of culture-negative fungal endocarditis, after Candida endocarditis. Typical risk factors include intravenous drug use, immunosuppression, prior cardiac surgery or presence of prosthetic heart valves ...

Bacterial biofilms use chiral branches to escape crowded environments by tracking oxygen gradient [PDF]

arXiv, 2022
Bacterial biofilms collectively develop distinct and ordered structures, including fibers, bundles, and branches. Often, it is unclear how these structural motifs convey specific advantages to bacterial strains under challenging conditions. In oxygen-limited environments, dense bacterial aggregates generally deplete oxygen, which leads to arrest of ...

Rheology of bacterial suspensions under confinement [PDF]

arXiv, 2019
As a paradigmatic model of active fluids, bacterial suspensions show intriguing rheological responses drastically different from their counterpart colloidal suspensions. Although the flow of bulk bacterial suspensions has been extensively studied, the rheology of bacterial suspensions under confinement has not been experimentally explored.

Effects of bacterial density on growth rate and characteristics of microbial-induced CaCO3 precipitates: a particle-scale experimental study [PDF]

arXiv, 2020
Microbial-Induced Carbonate Precipitation (MICP) has been explored for more than a decade as a promising soil improvement technique. However, it is still challenging to predict and control the growth rate and characteristics of CaCO3 precipitates, which directly affect the engineering performance of MICP-treated soils.

Effects of a 4‐week free‐sugar avoidance during periodontal therapy: An explorative randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background This study investigated the effect of a 4‐week free‐sugar avoidance on periodontal parameters during periodontal therapy. Methods Twenty‐one patients with untreated periodontitis and daily free‐sugar intake were allocated to a sugar avoidance group (SAG) and a control group (CG).

Efficacy of microbial cell‐free DNA testing for detecting pathogens in pediatric patients with head and neck infections—An initial study

Pediatric Investigation, EarlyView.
We investigate the utility of microbial cell‐free DNA (mcfDNA) from the blood to predict surgical culture results. In this study, only 26.9% of patients had mcfDNA results that were considered predictive of the causative organism(s). There was a significant burden of contamination in the cohort, emphasizing that dedicated protocols must be followed ...

PET-scan in diagnosis of non-bacterial thrombotic endocarditis: a case report

The Egyptian Heart Journal
Background Non-bacterial thrombotic endocarditis (NBTE), also known as marantic endocarditis or Libman–Sacks endocarditis, is a rare non-infectious condition affecting mostly the left-sided heart valves of patients who, most often, suffer from ...
