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

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.

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

Genes Cells
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 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.

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 ...

Fate of coliphage in a wastewater treatment process

Journal of Bioscience and Bioengineering, 2002
The fate of coliphage in a wastewater treatment plant in the central part of Japan was investigated from March to December 2001. A relative abundance of coliphage, 1000-10,000 PFU/ml determined with three different Escherichia coli strains, was detected in the influent.

Sorbitol MacConkey agar and wastewaters` coliphages [PDF]

Journal of Applied Research in Water and Wastewater, 2023
A total of 114 samples collected from hospital wastewaters and rivers in Addis Ababa, Ethiopia were tested for non-sorbitol fermenting bacteria and coliphages. Sorbitol MacConkey agar is mainly used in the detection of E. coli O157:H7.

Characterization of phage vB_EcoS-EE09 infecting E. coli DSM613 Isolated from Wastewater Treatment Plant Effluent and Comparative Proteomics of the Infected and Non-Infected Host

Microorganisms, 2023
Phages influence microbial communities, can be applied in phage therapy, or may serve as bioindicators, e.g., in (waste)water management. We here characterized the Escherichia phage vB_EcoS-EE09 isolated from an urban wastewater treatment plant effluent.
