Modeling the photoinactivation and transport of somatic and F-specific coliphages at a Great Lakes beach. [PDF]

J Environ Qual, 2020
AbstractFecal indicator organisms (FIOs), such as Escherichia coli and enterococci, are often used as surrogates of contamination in the context of beach management; however, bacteriophages may be more reliable indicators than FIO due to their similarity to viral pathogens in terms of size and persistence in the environment.

A new understanding of somatic coliphages belonging to the Microviridae family in urban wastewater

Water Research
Somatic coliphages (SC) and F-specific RNA coliphages (FRNAPH) have been included in regulations or guidelines by several developed countries as a way of monitoring water safety and the microbiological quality of shellfish harvesting waters. SC are highly diverse in their morphology, size and genome.

Enumeration of Somatic and F-RNA Phages as an Indicator of Fecal Contamination in Potable Water from Rural Areas of the North West Province

Pathogens, 2015
Bacteriophages are regarded as enteric viral indicators in faecally contaminated water systems and may indicate the presence of human viral pollution. They are relatively resistant to inactivation by natural and treatment processes.

Optimisation of the ISO-method on enumeration of somatic coliphages (draft ISO 10705-2)

Water Science and Technology, 2001
As part of the EU project “Bacteriophages in Bathing Waters” (January 1996 - June 1999) research was carried out to optimise the method for detection and enumeration of somatic coliphages in water as described in ISO/CD 10705-2 of August 1995. It was concluded that this draft ISO standard needed to be amended in certain aspects.

Clostridium perfringens and somatic coliphages as indicators of the efficiency of drinking water treatment for viruses and protozoan cysts. [PDF]

Appl Environ Microbiol, 1993
To find the most suitable indicator of viral and parasitic contamination of drinking water, large-volume samples were collected and analyzed for the presence of pathogens (cultivable human enteric viruses, Giardia lamblia cysts, and Cryptosporidium oocysts) and potential indicators (somatic and male-specific coliphages, Clostridium perfringens).

Efficient quantification of somatic coliphages in water: Development and validation of the Enumera® Rapid kit

Science of the Total Environment
The integration of somatic coliphage analysis into water quality regulations has driven the development of more streamlined, easier, and faster detection methods. These include the Bluephage method, initially designed for the qualitative assessment of coliphages in 100 mL water samples.

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 pathogenic microorganisms in small drinking-water systems in Costa Rica

Journal of Water and Health, 2022
This study describes the quality of drinking water sampled over 2 years (2018 and 2019) from 20 ASADAS (Spanish acronym for Administrative Associations for Water and Sewer Systems) in Costa Rica.

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 ...

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 ...
