Role of the Multicopper Oxidase CueO in Copper Homeostasis Under Anaerobic Conditions in Enterobacteria

Molecular Microbiology, EarlyView.
The periplasmic multicopper oxidase CueO oxidizes cuprous ions (Cu+) to cupric ions (Cu2+), a well‐known process typically coupled with oxygen reduction. In this study, we report unexpected anaerobic phenotypes associated with CueO, suggesting that it may use an alternative electron acceptor in the absence of oxygen.

A Small RNA Derived From the 5′ End of the IS200 tnpA Transcript Regulates Multiple Virulence Regulons in Salmonella typhimurium

Molecular Microbiology, EarlyView.
We show deletion of an IS200‐encoded sRNA (5′tnpA) in Salmonella impacts the expression of SPI‐1, flagellar, cysteine, and phsABC regulons. Evidence is presented that, with regard to the SPI‐1 regulon, 5′tnpA may function through base pairing with another sRNA known to regulate SPI1 called PinT.

FITNESS AND PATHOGENICITY OF OUTBREAK CAUSING Salmonella UPON SHORT-TERM EXPOSURE TO GROUNDWATER WITH RESIDUAL ANTIBIOTICS

Trakya University Journal of Natural Sciences, 2019
The changes in survival and pathogenicity of three Salmonella enterica subsp. enterica serotypes upon short term exposure to groundwater with residual antibiotics have been studied in relationship to overall microbial fitness.

Cellular view of metabolism: metabolic biomolecular condensates

New Phytologist, EarlyView.
Summary Recent studies across biological systems highlight an important function of biomolecular condensates (hereafter biocondensates) in regulating physiology. Biocondensates are membraneless organelles that compartmentalize cellular processes and allow regulatory control of key biomolecules through their assembly and disassembly. Biocondensates have

Isolation of Salmonella enterica subsp. enterica (O:4,5:i) and Salmonella enterica subsp. Typhimurium from free-living domestic pigeons (Columba livia)

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
The present study reports the isolation of Salmonella enterica in organs of free-living domestic pigeons. In the clinic examination, the presence of feces in the peri-cloacal and abdominal regions were observed, as well as symptoms such as cachexy ...

Prevalence, Risk Factors, and Human Health Implications of Salmonella enterica and Campylobacter spp. in Vermont Backyard Poultry

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Backyard poultry (BYP) are increasingly linked to cases of campylobacteriosis and salmonellosis. Methods Between 2022 and 2024, soiled bedding samples from 70 BYP farms were tested for Campylobacter spp. and/or Salmonella enterica. Results Nine farms (12.86%) had at least one sample positive for S.
