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.

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

Water 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 ...

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

Antibiotics, 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.

Coliphages as indicators of primary wastewater treatment efficiency by constructed wetlands

Journal 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 ...

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.

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.

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 ...

Replication of coliphage lambda DNA [PDF]

FEMS Microbiology Reviews, 1995
A general scheme of lambda phage and plasmid DNA replication in Escherichia coli is presented, and results of in vivo experiments from the authors' laboratory are superimposed. The initiator lambda O functions in the assembly of the replication complex (RC) at ori lambda, making it a stable component of this structure.
