Long-Read Sequencing Reveals Evolution and Acquisition of Antimicrobial Resistance and Virulence Genes in Salmonella enterica

open access: yesFrontiers in Microbiology, 2021
Salmonella enterica is a significant and phylogenetically diverse zoonotic pathogen. To understand its genomic heterogeneity and antimicrobial resistance, we performed long-read sequencing on Salmonella isolated from retail meats and food animals.

Characterization of Biofilm Formation by Mycobacterium chimaera on Medical Device Materials

open access: yesFrontiers in Microbiology, 2021
Non-tuberculous mycobacteria (NTM) are widespread in the environment and are a public health concern due to their resistance to antimicrobial agents. The colonization of surgical heater-cooler devices (HCDs) by the slow-growing NTM species Mycobacterium ...

bettercallsal: better calling of Salmonella serotypes from enrichment cultures using shotgun metagenomic profiling and its application in an outbreak setting

open access: yesFrontiers in Microbiology, 2023
Most current Salmonella subtyping analyses rely on whole genome sequencing (WGS), which focuses on the high-resolution analysis of single genomes or multiple single genomes from the isolated colonies on microbiological agar plates.

Machine learning models for rat multigeneration reproductive toxicity prediction

open access: yesFrontiers in Pharmacology, 2022
Reproductive toxicity is one of the prominent endpoints in the risk assessment of environmental and industrial chemicals. Due to the complexity of the reproductive system, traditional reproductive toxicity testing in animals, especially guideline ...

Development of QSAR models to predict blood-brain barrier permeability

open access: yesFrontiers in Pharmacology, 2022
Assessing drug permeability across the blood-brain barrier (BBB) is important when evaluating the abuse potential of new pharmaceuticals as well as developing novel therapeutics that target central nervous system disorders.

High-Resolution Microbiome Profiling for Detection and Tracking of Salmonella enterica

open access: yesFrontiers in Microbiology, 2017
16S rRNA community profiling continues to be a useful tool to study microbiome composition and dynamics, in part due to advances in next generation sequencing technology that translate into reductions in cost.

Changes in the genomes and methylomes of three Salmonella enterica serovars after long-term storage in ground black pepper

open access: yesFrontiers in Microbiology, 2022
Low moisture foods (LMFs) have traditionally been recognized as safe for consumption, as most bacteria require higher water content to grow. However, outbreaks due to LMF foods are increasing, and the microbial pathogen Salmonella enterica is frequently ...

Comparative Genomic Characterization of the Highly Persistent and Potentially Virulent Cronobacter sakazakii ST83, CC65 Strain H322 and Other ST83 Strains

open access: yesFrontiers in Microbiology, 2017
Cronobacter (C.) sakazakii is an opportunistic pathogen and has been associated with serious infections with high mortality rates predominantly in pre-term, low-birth weight and/or immune compromised neonates and infants.

Testing of a commercial waterpipe electric heater and a research-grade waterpipe electric heater

open access: yesTobacco Prevention and Cessation, 2020
Introduction The capability of a commercial waterpipe electric heater to simulate the waterpipe charcoal heating system using waterpipe tobacco consumption as a metric was evaluated, and a research-grade waterpipe electric heater to standardize waterpipe

Aging-Induced Dysbiosis of Gut Microbiota as a Risk Factor for Increased Listeria monocytogenes Infection

open access: yesFrontiers in Immunology, 2021
Invasive foodborne Listeria monocytogenes infection causes gastroenteritis, septicemia, meningitis, and chorioamnionitis, and is associated with high case-fatality rates in the elderly.
