Evaluation and Comparison of the UV-LED Action Spectra for Photochemical Disinfection of Coliphages and Human Pathogenic Viruses [PDF]

Microorganisms
Ultraviolet (UV) disinfection is a powerful method for inactivating viruses. However, comparative wavelength-dependent sensitivities among human viruses and bacteriophages remain poorly characterized.

A Bayesian Model for Estimation of Virus Reduction in Potable Reuse Treatment Trains and Quantitative Microbial Risk Assessment of Waterborne Viral Pathogens [PDF]

Risk Analysis, Volume 46, Issue 9, September 2026.
ABSTRACT Understanding virus occurrence and reduction at advanced treatment facilities for potable water reuse constitutes a high‐priority research need to protect human health and to enhance available water supply alternatives. The objectives were to (1) determine log reduction values (LRVs) of 15 viruses by advanced wastewater treatment; (2) evaluate

Carboxyl‐Terminal Region of the Maturation Protein of RNA Coliphage Qβ Mediates Host Attachment, Virion Formation, and Cell Lysis [PDF]

Genes to Cells, Volume 31, Issue 2, March 2026.
The 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.

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

Water Environment Research, Volume 97, Issue 9, September 2025.
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.

Reverse Genetics of Orthoflaviviruses: Strategies for Constructing Functional or Infectious cDNA [PDF]

Journal of Medical Virology, Volume 98, Issue 6, June 2026.
ABSTRACT Reverse genetics (RG) systems have transformed RNA virus research by enabling the recovery of recombinant viruses entirely from cloned cDNA. These platforms allow precise, hypothesis‐driven manipulation of viral genomes and support systematic phenotypic analyses in vitro and in vivo.

Flow Virometry in Wastewater Monitoring: Comparison of Virus-like Particles to Coliphage, Pepper Mild Mottle Virus, CrAssphage, and Tomato Brown Rugose Fruit Virus [PDF]

Viruses
Flow virometry (FVM) offers a promising approach for monitoring viruses and virus-like particles (VLPs) in environmental samples. This study compares levels of non-specific VLPs across a wastewater treatment plant (WWTP) with levels of somatic coliphage,

Atlas of Interactions Between Decoration Proteins and Major Capsid Proteins of Coliphage N4 [PDF]

Viruses
Coliphage N4 is a representative species of the Schitoviridae family of bacteriophages. Originally structurally studied in 2008, the capsid structure was solved to 14 Å to reveal an interesting arrangement of Ig-like decoration proteins across the ...

The Structure of Coliphages [PDF]

Journal of General Microbiology, 1963
SUMMARY: The detailed morphology of several new coliphages is compared with that of the more familiar types; the resulting information is considered for its taxonomic value. Some were examined at molecular level and new information on the tail structure of the ‘T even’ phages is described.
