Detection of Microbial Contaminants in Water: Conventional Methods, Pragmatic Alternatives, and Nanosensing Techniques

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Conventional culture and immunological methods of detecting bacterial water contaminants have some limitations. There are alternative pragmatic methods which are more efficient and faster in the detection of bacteria in water, especially nanosensors. ABSTRACT The complexities of microbial detection and conventional enumeration necessitates the adoption

Indication of Cross-Species Transmission of Astrovirus Associated with Encephalitis in Sheep and Cattle

Emerging Infectious Diseases, 2017
We report the identification of a neurotropic astrovirus associated with encephalitis in a sheep. This virus is genetically almost identical to an astrovirus recently described in neurologically diseased cattle. The similarity indicates that astroviruses

Astrovirus and the microbiome

Current Opinion in Virology, 2019
Although astroviruses are most commonly associated with acute gastrointestinal illness in humans, their ability to infect a broad range of hosts and cause a spectrum of disease makes them widespread and complex pathogens. The precise mechanisms that dictate the course of astrovirus disease have not been studied extensively but are likely driven by ...

CVID Enteropathy Associated With Chronic Norovirus Infection: Background, Clinical Features, and Therapeutic Aspects

Reviews in Medical Virology, Volume 35, Issue 6, November 2025.
ABSTRACT Common variable immunodeficiency (CVID) is the most prevalent symptomatic primary immunodeficiency, characterised by impaired antibody production, immune dysregulation, and a broad spectrum of clinical manifestations. Gastrointestinal involvement is frequent, affecting up to 20% of patients and significantly contributing to morbidity and ...

Astrovirus survival in drinking water [PDF]

Applied and Environmental Microbiology, 1997
A method based on infection of CaCo-2 cultured cell monolayers (CC) and reverse transcription-PCR (RT-PCR) was developed for the specific detection of infectious astrovirus. The procedure was validated by titrating poliovirus stocks in parallel in CaCo-2 cells by determining the most probable number of cytopathogenic units and by cell culture and ...
