The objective of this study was to explore the genetic and biological features of the tet(M)-harboring plasmid pTS14 in Salmonella enterica strain S14 isolated from a chicken fecal sample. Plasmid pTS14 was identified by conjugation, S1-pulsed-field gel electrophoresis (PFGE), Southern hybridization, and plasmid sequencing. The biological characteristics of pTS14 were assessed via stability, growth kinetics, and starvation survival experiments. Strain S14, belonging to ST3007, harbored a 119-kb tet(M)-bearing IncF2:A1:B1 conjugative plasmid pTS14. The plasmid pTS14 contained a novel transposon Tn6709 with the genetic struc...

Contributors : Alexandre Duprey ; Eduardo A GroismanSeries Type : Expression profiling by high throughput sequencingOrganism : Salmonella enterica subsp. enterica serovar TyphimuriumDNA supercoiling is essential for life because it controls critical processes, including transcription, replication and recombination. Current methods to measure DNA supercoiling in vivo are laborious and unable to examine single cells. Here we report a method for high-throughput measurement of bacterial DNA supercoiling in vivo. Fluorescent Evaluation of DNA Supercoiling (FEDS) utilizes a plasmid harboring the gene for a green fluorescent prot...

by Marie-France Phoba, Barbara Barb é, Benedikt Ley, Sandra Van Puyvelde, Annelies Post, Wesley Mattheus, Stijn Deborggraeve, Octavie Lunguya, Jan Jacobs BackgroundNon-typhoidalSalmonella (NTS) serotypes Typhimurium and Enteritidis are a major cause of bloodstream infections in children in sub-Saharan Africa but their reservoir is unknown. We compared pairs of NTS blood and stool isolates (with the same NTS serotype recovered in the same patient) for genetic similarity. MethodsBetween November 2013 and April 2017, hospital-admitted children (29 days to 14 years) with culture-confirmed NTS bloodstream infections were...

olińska The development of nanotechnology in the last two decades has led to the use of silver nanoparticles (AgNPs) in various biomedical applications, including antimicrobial, anti-inflammatory, and anticancer therapies. However, the potential of the medical application of AgNPs depends on the safety of their use. In this work, we assessed the in vitro cytotoxicity and genotoxicity of silver nanoparticles and identified biomolecules covering AgNPs synthesized from actinobacterial strain SH11. The cytotoxicity of AgNPs against MCF-7 human breast cancer cell line and murine macrophage cell line RAW 264.7 was studied b...

(University of Delaware) Researchers have discovered that bacteria such as salmonella, E.coli and listeria have a backdoor to take advantage of humans' reliance on leafy greens for a healthy diet. They found that wild strains of salmonella are delivering foodborne illnesses by circumventing a plant's immune defense system, getting into the leaves of lettuce by opening up the plant's tiny breathing pores.

Abstract A total of 15 samples of thalassotherapy products, distributed in Tunisia in their intact and final state of production, was analyzed to determine their microbiological safety status. The result shows the absence of pathogenic bacteria (Staphylococcus aureus, Candida albicans, Salmonella, Pseudomonas aeruginosa and coliforms). The incidence of contamination by Gram-positive Bacilli (mesophelic bacteria, aerobic and anaerobic spore forming bacteria, anaerobic sulphite-reducing bacteria) was found to be higher in products composed by mud and extract of alga. The biochemical and molecular identification of t...
