Viable but Nonculturable State, a Survival Strategy for Salmonella in Aquatic Environments

Water and Environment Journal, Volume 40, Issue 2, Page 183-202, May 2026.
Transition of Salmonella from a culturable state to a viable but nonculturable state under various environmental stresses and current methods for detecting viable Salmonella in environmental samples. ABSTRACT In the relentless battle for survival, Salmonella has evolved mechanisms to withstand harsh conditions such as extreme temperatures, fluctuating ...

Investigation of Recombinantly Produced Endolysins Reveals a Modular Enzyme Shared by Several Enterobacteria Phages to Exhibit Broad‐Range Lytic Activity Against Different Orders of Gammaproteobacteria

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
The recombinant endolysin El1 derived from Enterobacteria bacteriophages showed potent bactericidal activity against Gram‐negative bacteria when applied exogenously, even in the absence of membrane‐permeabilizing agents, such as ethylenediaminetetraacetic acid (EDTA).

A Comprehensive Review of the Multitarget Effects of Subinhibitory Concentrations of Essential Oils Against Salmonella

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT Essential oils (EOs) exhibit antimicrobial activity against foodborne pathogens due to their chemical composition. This review investigates the mechanisms of action of EOs at subinhibitory concentrations against Salmonella strains. Even at subinhibitory concentrations, EOs induce cellular stress and modulate bacterial metabolism. EOs interfere

Penetration of Salmonella enteritidis and Salmonella heidelberg into egg yolks in an in vitro contamination model

Poultry Science, 2005
Eggs that harbor Salmonella in their edible contents pose a significant risk of transmitting disease to consumers. Although Salmonella deposition inside yolks does not usually occur at a high frequency in naturally contaminated eggs, bacterial penetration through the vitelline membrane could lead to rapid and extensive multiplication in the nutrient ...

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

The FEBS Journal, Volume 293, Issue 6, Page 1801-1817, March 2026.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...

Antibacterial Activity of Estragole From Ocimum tenuiflorum, and Tagetes lucida and Synergistic Effect With Meropenem and Tobramycin Against Multidrug‐ and Extensively Drug‐Resistant (MDR‐XDR) Gram‐Negative Bacteria

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
This study reveals estragole's bactericidal activity against MDR/XDR Gram‐negative pathogens. Synergy with meropenem and tobramycin was observed in > 88% of strains, reducing antibiotic MICs up to 16‐fold. Estragole represents a promising therapeutic adjuvant to enhance antibiotic efficacy and combat antimicrobial resistance.

Prophage Integrase Typing Is a Useful Indicator of Genomic Diversity in Salmonella enterica

Frontiers in Microbiology, 2017
Salmonella enterica is a bacterial species that is a major cause of illness in humans and food-producing animals. S. enterica exhibits considerable inter-serovar diversity, as evidenced by the large number of host adapted serovars that have been ...

Research Note: Reduction of Salmonella load in Brazilian commercial chicken farms using INSPEKTOR®: a bacteriophage-based product

Poultry Science
Salmonella is a zoonotic pathogen transmitted through food and one of the four leading global causes of diarrheal disease in humans. Brazil is the world's largest exporter of poultry meat, and as such, Brazilian farms routinely detect and prevent ...

Comparison of three diagnostic methods for Salmonella enterica serovars detection in chicken rinse

Pesquisa Veterinária Brasileira
: Salmonella detection is a key point in food safety testing, because of the frequent association of this pathogen with food poisoning in humans. The standard bacteriological tests currently used for Salmonella-detection are time-consuming; therefore ...
