Salmonellosis represents a growing threat to global public health. Salmonella enterica remains the leading cause of bacterial foodborne diseases in China. Salmonella enterica serovar Rissen (S. Rissen) has been recognized as one of the emerging serovars among humans in different countries worldwide. However, knowledge on the prevalence of S. Rissen in China is largely lacking. To address essential epidemiological information for S. Rissen in China, a total of 1,182 S.

Non-typhoidal Salmonella (NTS) is a common cause for self-limiting gastroenteritis, representing a public health concern globally. NTS is one of the leading causes of foodborne illnesses in China; however, the invasive infection caused by NTS is largely underappreciated.

Introduction. The emergence and spread of non-typhoidal Salmonella enterica (NTS) serovars resistant to fluoroquinolones and third- and higher-generation cephalosporins is a matter of great concern.

Journal of Applied Microbiology, Accepted Article. ABSTRACT
Aims
In this study, the efficacy of using vacuumed hydrogen peroxide vapor (VHPV) to inactivate foodborne pathogens in whole dried black pepper (Piper nigrum) and powdered dried red pepper (Capsicum annuum) was evaluated.

In Japan’s Kanto region, the number of Salmonella enterica serovar Chester infections increased temporarily between 2014 and 2016. Concurrently with this temporal increase in the Kanto region, S. Chester isolates belonging to one clonal group were causing repetitive outbreaks in Europe. A recent study reported that the European outbreaks were associated with travelers who had been exposed to contaminated food in Morocco, possibly seafood.

The aim of this study was to investigate the growth-inhibitory effects of X-ray irradiation against gram-negative (Escherichia coli O157:H7 and Salmonella Typhimurium) and gram-positive pathogenic bacteria (Listeria monocytogenes and Staphylococcus aureus) in apple, orange, and tomato juices. Additionally, the effects of X-ray irradiation on juice quality attributes were examined. Upon irradiation with 0.8 kGy X-ray, the counts of E.

Introduction

Abstract

Salmonella enterica serovar Enteritidis is a major cause of foodborne Salmonella infections and outbreaks in humans.

The effect of gamma radiation on the decontamination of microbial population, physico-chemical, radiation sensitivity and sensory characteristics of common spices for storage were evaluated. Spices were irradiated with gamma doses of 0 (as control), 2, 4, 6, 8 and 10 kGy, packed in the glass vials and stored at room temperature (22 ± 2°C) in the laboratory.

L-arabinose inducible promoters are commonly used in gene expression analysis. However, nutrient source and availability also play a role in biofilm formation; therefore, L-arabinose metabolism could impact biofilm development. In this study we examined the impact of L-arabinose on Salmonella enterica serovar Typhimurium (S. Typhimurium) biofilm formation. Using mutants impaired for the transport and metabolism of L-arabinose, we showed that L-arabinose metabolism negatively impacts S.

ABSTRACT Bacteria may enter into a viable but nonculturable (VBNC) state as a response to stresses, such as those found in food processing. Cells in the VBNC state lose the ability to grow in a conventional culture medium but man recover culturability. The viability, culturability and intracellular reactive oxygen species (ROS) of Salmonella Enteritidis and Shigella flexneri were evaluated under stress conditions to induce a VBNC state.

The emergence and spread of multidrug-resistant Salmonella enterica (S. enterica) to humans through food of animal origin are considered a major global public health concern. Currently, little is known about the prevalence of important antimicrobial resistance genes in S. enterica from retail food in Africa. Therefore, the screening and characterization of the extended-spectrum β-lactamase (ESBL) and plasmid-mediated quinolone resistance (PMQR) genes in S.

This study innovatively produced polymeric active antibacterial films by incorporating zinc oxide nanoparticles (ZnO-NP) into linear low-density polyethylene grafted with maleic anhydride (LLDPE-MA) and low-density polyethylene (LDPE) using polymer melting and coating of ZnO-NP.
