Coliphages of the human urinary microbiota. [PDF]
PLoS ONE, 2023 Due to its frequent association with urinary tract infections (UTIs), Escherichia coli is the best characterized constituent of the urinary microbiota (urobiome). However, uropathogenic E. coli is just one member of the urobiome. In addition to bacterial

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

Carboxyl-Terminal Region of the Maturation Protein of RNA Coliphage Qβ Mediates Host Attachment, Virion Formation, and Cell Lysis. [PDF]
Genes CellsThe capsid of the single‐stranded RNA coliphage Qβ has a maturation (A2) protein that penetrates the capsid. The N‐terminal β‐region of A2 is exposed on the surface, and the C‐terminal α‐region is located inside the capsid and binds the genomic RNA. In this study, we showed that Qβ attached to the F‐pilus of the host via A2.

Diverse Temperate Coliphages of the Urinary Tract [PDF]
VirusesWhile Escherichia coli can be found in the bladders of females without lower urinary tract symptoms, its presence is often associated with urinary tract infections (UTIs). The genomic plasticity of E. coli, including urogenital strains, is largely shaped

Evaluation and Comparison of the UV-LED Action Spectra for Photochemical Disinfection of Coliphages and Human Pathogenic Viruses [PDF]
MicroorganismsUltraviolet (UV) disinfection is a powerful method for inactivating viruses. However, comparative wavelength-dependent sensitivities among human viruses and bacteriophages remain poorly characterized.

The Effect of Protozoa Indigenous to Lakewater and Wastewater on Decay of Fecal Indicator Bacteria and Coliphage [PDF]
Pathogens, 2023 Fecal indicator bacteria (FIB: Escherichia coli and enterococci) are used to assess recreational water quality. Viral indicators (i.e., somatic and F+ coliphage), could improve the prediction of viral pathogens in recreational waters, however, the impact

Coliphages as viral indicators of sanitary significance for drinking water [PDF]
Frontiers in Microbiology, 2022 Coliphages are virus that infect coliform bacteria and are used in aquatic systems for risk assessment for human enteric viruses. This mini-review appraises the types and sources of coliphage and their fate and behavior in source waters and engineered ...
