Exploring Bacterial Interactions Under the Stress Gradient Hypothesis in Response to Selenium Stress

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Under the model of the stress gradient hypothesis, as selenium (Se) stress increases, bacterial interactions shift from net competitive (low stress) to net facilitative/helpful interactions (high stress). This allows Se susceptible species to benefit from detoxification mechanisms provided by Se detoxifying bacteria which remove toxins from the ...

Molecular Identification of the colicin types in Escherichia coli in the Yasuj city

open access: yesArmaghane Danesh Bimonthly Journal, 2014
Background & aim: colicins are a group of bacteriocins produce by Escherichia coli and act against pathogenic bacteria Escherichia coli. Today, the use of colicinogenic strains as probiotic microorganisms and replace them instead of the combination of ...

Identification and Evaluation of the Urinary Microbiota Associated With Bladder Cancer

open access: yesCancer Innovation, Volume 4, Issue 4, August 2025.
Urinary microbiota in Chinese bladder cancer patients reveals distinct profiles between non‐muscle‐invasive and muscle‐invasive diseases, with potential biomarkers like Peptoniphilus spp. in high‐risk MIBC, suggesting a role in cancer progression. Dysbiosis may serve as a stratification marker for bladder cancer risk. ABSTRACT Background Bladder cancer

Synthetic Biology‐Based Engineering Living Therapeutics for Antimicrobial Application

open access: yesExploration, Volume 5, Issue 4, August 2025.
This perspective highlights synthetic biology‐driven antibacterial strategies, focusing on three innovative approaches: engineered bacteriophages for precision bacterial targeting, reprogrammed microbes that detect quorum‐sensing signals or metabolites to release antimicrobials, and engineering mammalian cells that recognize pathogen‐associated ...

Assessing the Antibiotic Resistance in Food Lactic Acid Bacteria: Risks in the Era of Widespread Probiotic Use

open access: yesFood Science &Nutrition, Volume 13, Issue 8, August 2025.
Targeting the potential sources and risk factors for antibiotic resistance transmittance and development of antibiotic resistant‐free probiotics. ABSTRACT Antibiotic resistance (AR) in lactic acid bacteria (LAB) has become an emerging concern in the probiotic and food industries. LAB, a key component of the human microbiota and widely used in probiotic

Detection of Colicin genes by PCR in Escherichia coli isolated from cattle in Shiraz-Iran

open access: yesArchives of Razi Institute, 2012
A variety of probiotic bacteria have been tested to control animal and foodborne pathogenic bacteria in livestock. The mechanism of inhibition of pathogenic bacteria for several of those probiotic microorganisms is mediated by the production of ...

COLICINE K [PDF]

open access: yesThe Journal of Experimental Medicine, 1960
The synthesis of colicine K by the colicinogenic bacillus E. coli K235 has been studied in the chemostat. It has been found that colicine production is influenced by the pH of the medium, by the nature of the primary carbon source, and by the generation time of the microorganism.

A novel vector for positive selection of inserts harboring an open reading frame by translational coupling

open access: yesBioTechniques, 2007
We have developed a novel vector, pTCS, as a tool for efficient selection of open reading frame (ORF)-containing inserts. In pTCS clones containing an insert with an ORF, a downstream marker gene (immE3, conferring resistance to colicin) is activated via
