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.

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.

Partial Characterization of Coliphage WPK and a Comparison with Coliphage T3 [PDF]

Microbiology and Immunology, 1992
AbstractColiphage WPK was originally isolated from sewage in Kiel, Germany, because its plaque diameter continued to expand for days. Electron microscopy revealed an isometric capsid with dimensions of 54 nm between opposite apices, and a short, noncontractile tail 16 nm long, placing phage WPK into morphogroup C1.

Comparison between the Biofilm Desorption Abilities of T4 and MS2 Coliphages

Applied Sciences, 2022
Biofilms are a collection of microorganisms that adhere to a surface where they continue to grow. Firmly established biofilms can be hazardous to human health.

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.

Coliphages as viral indicators of sanitary significance for drinking water

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 ...

Decay of infectious adenovirus and coliphages in freshwater habitats is differentially affected by ambient sunlight and the presence of indigenous protozoa communities

Virology Journal, 2020
Background Sanitary quality of recreational waters worldwide is assessed using fecal indicator bacteria (FIB), such as Escherichia coli and enterococci. However, fate and transport characteristics of FIB in aquatic habitats can differ from those of viral

Coliphages as Indicators of Fecal Contamination in Wastewater Treatment (SCA.Re.S. Project)

Medical Sciences Forum, 2021
Bacteriophages are fecal indicators of viral contamination, because they are more similar to human pathogenic viruses than the traditional fecal indicator bacteria, in terms of log-reduction during wastewater treatment and persistence in the aquatic ...

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.

Occurrence of coliphage in effluent: A systematic literature review and meta-analysis

Hygiene and Environmental Health Advances, 2022
Studies have illustrated that wastewater treatment methods targeting bacteria do not remove all types of viruses and available epidemiological studies indicate bacteria concentrations may not always be predictive of viral illnesses associated with ...
