A prophage-encoded sRNA limits phage infection of adherent-invasive E. coli. [PDF]

open access: yesPLoS Pathogens
Prophages are prevalent features of bacterial genomes that can reduce susceptibility to infection by competing phages, yet the mechanisms involved are often elusive.

Treatment of E. coli Infections with T4-Related Bacteriophages Belonging to Class Caudoviricetes: Selecting Phage on the Basis of Their Generalized Transduction Capability [PDF]

open access: yesViruses
The problem of the multidrug resistance of pathogenic bacteria is a serious concern, one which only becomes more pressing with every year that passes, motivating scientists to look for new therapeutic agents.

Comparative study of enteric viruses, coliphages and indicator bacteria for evaluating water quality in a tropical high-altitude system

open access: yesEnvironmental Health, 2009
Background Bacteria used as indicators for pathogenic microorganisms in water are not considered adequate as enteric virus indicators. Surface water from a tropical high-altitude system located in Mexico City that receives rainwater, treated and non ...

Prophage Induction of Noninducible Coliphage 186 [PDF]

open access: bronzeJournal of Virology, 1974
Coliphage 186 has been regarded as a member of the noninducible group of coliphages. Evidence that prophage 186 is induced by ultraviolet irradiation or by treatment with nalidixic acid or mitomycin C is now presented. The phage yields were similar to those from lysogens of the inducible phage lambda, and the induction required a

Virus Log Reduction Values and Dominant Mechanisms in Full-Scale Secondary Biological Wastewater Treatment Systems. [PDF]

open access: yesWater Environ Res
For secondary treatment, the dominant virus removal mechanism varies based on system type and method(s) used to quantify virus reduction. This study demonstrates that secondary treatment can achieve significant virus reduction, but regulatory crediting for direct potable reuse may still not be justified.

Occurrence of pathogenic microorganisms in small drinking-water systems in Costa Rica

open access: yesJournal of Water and Health, 2022
This study describes the quality of drinking water sampled over 2 years (2018 and 2019) from 20 ASADAS (Spanish acronym for Administrative Associations for Water and Sewer Systems) in Costa Rica.

Occurrence of male-specific and somatic coliphages and relationship with rainfall in privately-owned wells from peri‑urban and rural households

open access: yesWater Research X, 2021
Privately-owned drinking water wells serving fewer than 25 people (private wells) are prevalent and understudied across most of the US. Private wells primarily serve rural households located outside of municipal drinking water and sewerage service ...

Coliphages as indicators of primary wastewater treatment efficiency by constructed wetlands

open access: yesJournal of Water and Health, 2023
Constructed wetlands are an efficient and cost-effective system for the treatment of wastewater that can be reused for diverse purposes, including irrigation; however, few studies have determined the efficiency of microbial removal by constructed ...

Detection and Level Evaluation of Antibodies Specific to Environmental Bacteriophage I11mO19 and Related Coliphages in Non-Immunized Human Sera

open access: yesAntibiotics, 2023
Bacteriophages (phages) are viruses infecting bacteria. They are widely present in the environment, food, and normal microflora. The human microbiome is a mutually interdependent network of bacteria, bacteriophages, and human cells.
