Surface water as a source of rare Salmonella enterica serovars in semiarid northeastern Brazil

Journal of Environmental Quality, EarlyView.
Abstract Salmonella enterica remains a major foodborne pathogen globally but little attention has been paid to infrequent serovars in environmental settings. We report the occurrence of 30 rare S. enterica serovars isolated from environmental water sources between 2021 and 2022 in semiarid northeastern Brazil.

Neutral genomic microevolution of a recently emerged pathogen, salmonella enterica serovar agona [PDF]

, 2013
Salmonella enterica serovar Agona has caused multiple food-borne outbreaks of gastroenteritis since it was first isolated in 1952. We analyzed the genomes of 73 isolates from global sources, comparing five distinct outbreaks with sporadic infections as

Mechanisms of resistance in Salmonella enterica

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork, 2003
The aim of this study was to promote resistance in Salmonella enterica serovar Enteritidis, Typhimurium, and Virchow to commonly used antibacterials and to identify mechanisms underlying any resistance obtained. Strains were exposed to various biocides and following each passage adaptive resistance was recorded.

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Proteomic Changes in Cancer Cell Lines as a Result of Bacterial Infection

PROTEOMICS, EarlyView.
ABSTRACT Bacterial infections have been implicated in shaping the tumor microenvironment (TME), but their effects on cancer cell proteomes remain unexplored. In this study, we analyzed proteomic changes in melanoma (A375) and ovarian cancer (OVCAR3) cell line models following infection with Staphylococcus aureus strain USA300 or Salmonella enterica ...

Novel Inducers of the Envelope Stress Response BaeSR in Salmonella Typhimurium: BaeR Is Critically Required for Tungstate Waste Disposal [PDF]

, 2011
The RpoE and CpxR regulated envelope stress responses are extremely important for SalmonellaTyphimurium to cause infection in a range of hosts. Until now the role for BaeSR in both the Salmonella Typhimurium response to stress and its contribution to ...

Characterization of multidrug-resistant Salmonella enterica serovars Indiana and Enteritidis from chickens in Eastern China.

PLoS ONE, 2014
A total of 310 Salmonella isolates were isolated from 6 broiler farms in Eastern China, serotyped according to the Kauffmann-White classification. All isolates were examined for susceptibility to 17 commonly used antimicrobial agents, representative ...

From Membrane Composition to Antimicrobial Strategies: Experimental and Computational Approaches to AMP Design and Selectivity

Small, EarlyView.
Antimicrobial peptides (AMPs) are promising candidates for next‐generation antibiotics, acting through mechanisms such as membrane disruption and intracellular targeting. This review examines how variations in bacterial membrane composition critically influence AMP activity.

Broad-spectrum β-lactamases among Enterobacteriaceae of animal origin: molecular aspects, mobility and impact on public health [PDF]

, 2010
Broad-spectrum β-lactamase genes (coding for extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases) have been frequently demonstrated in the microbiota of food-producing animals. This may pose a human health hazard since these genes may be present
