The Tum Protein of Coliphage 186 Is an Antirepressor [PDF]

Journal of Biological Chemistry, 1998
The tum gene of coliphage 186, encoded on a LexA controlled operon, is essential for UV induction of a 186 prophage. Primer extension analysis is used to confirm that Tum is the sole phage function required for prophage induction and that it acts against the maintenance repressor, CI, to relieve repression of the lytic promoters, pR and pB, and thereby

Cold Surface Waters of the Sub‐Antarctic Pacific Ocean Support High Cyanophage Abundances and Infection Levels

Environmental Microbiology, Volume 27, Issue 1, January 2025.
Here, we investigated the abundance of cyanophages and the extent to which they infect Synechococcus and Prochlorococcus, important primary producers, in the cold, low‐light, iron‐limited, sub‐Antarctic waters of the Pacific Ocean. We found that cyanophages are significant mortality agents, leading to substantial losses of these picocyanobacteria ...

Evaluation of the Ratio of Spot Tests and Plaque-Forming Activity Tests of Bacteriophages of Prevalent Pathogens

Эпидемиология и вакцинопрофилактика
Relevance. Obtaining clean lysis spots, with tolerable presence of individual colonies of secondary growth, in spot tests is a criterion for assessing the effectiveness of therapeutic bacteriophages.

Limitation of the Lytic Effect of Bacteriophages on Salmonella and Other Enteric Bacterial Pathogens and Approaches to Overcome

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
Bacteriophages (phages) have emerged as promising agents for combating bacterial pathogens, including nontyphoidal Salmonella enterica (S. enterica), the most common foodborne pathogen worldwide. The emergence of antimicrobial‐resistant (AMR) S. enterica poses a severe healthcare issue.

Impact of flocculated and softened particles on UV254 inactivation of indigenous spores

AWWA Water Science, Volume 6, Issue 6, November/December 2024.
Abstract US regulatory ultraviolet (UV) disinfection credit is typically granted when turbidity is ≤1 NTU. However, studies show turbidity does not always correlate well with UV dose responses. This study examined the impact of worst‐case high turbidity scenarios at drinking water treatment plants on UV254 inactivation of indigenous spores from ...

Wastewater treatment risks and challenges for public health and the environment during the Covid‐19 pandemic: a review

Journal of Chemical Technology &Biotechnology, Volume 99, Issue 10, Page 2119-2128, October 2024.
Abstract During the coronavirus disease 2019 (COVID‐19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), viral transport, fate, disinfection and environmental release in wastewater treatment plants have been issues of high importance for overall management.

Diversity and Local Coadaptation of Escherichia coli and Coliphages From Small Ruminants

Frontiers in Microbiology, 2020
Bacteriophages are highly specific predators that drive bacterial diversity through coevolution while striking tradeoffs among preserving host populations for long-term exploitation and increasing their virulence, structural stability, or host range ...

Three New Escherichia coli Phages from the Human Gut Show Promising Potential for Phage Therapy. [PDF]

PLoS ONE, 2016
With the emergence of multi-drug resistant bacteria the use of bacteriophages (phages) is gaining renewed interest as promising anti-microbial agents. The aim of this study was to isolate and characterize phages from human fecal samples.

Tracking epidemic viruses in wastewaters

Microbial Biotechnology, Volume 17, Issue 10, October 2024.
Wastewater‐based epidemiology has emerged as a highly powerful, innovative, flexible, cost‐effective, and scalable tool for pathogen surveillance, which has been successfully used for monitoring various diseases. Abstract Classical epidemiology relies on incidence, mortality rates, and clinical data from individual testing, which can be challenging for
