Genetic diversity of noroviruses in Brazil [PDF]

Memórias do Instituto Oswaldo Cruz, 2011
Norovirus (NoV) infections are a major cause of acute gastroenteritis outbreaks around the world. In Brazil, the surveillance system for acute diarrhoea does not include the diagnosis of NoV, precluding the ability to assess its impact on public health. The present study assessed the circulation of NoV genotypes in different Brazilian states by partial

Seroprevalence of Norovirus Genogroup IV Antibodies among Humans, Italy, 2010–2011

Emerging Infectious Diseases, 2014
Noroviruses (NoVs) of genogroup IV (GIV) (Alphatron-like) cause infections in humans and in carnivorous animals such as dogs and cats. We screened an age-stratified collection of serum samples from 535 humans in Italy, using virus-like particles of ...

Noroviruses: State of the Art [PDF]

Food and Environmental Virology, 2010
Noroviruses are a common cause of both endemic and epidemic gastroenteritis. These highly infectious viruses usually cause self-limited disease, but chronic infections occur in highly immunocompromised patients and unusual manifestations are also being described in some populations.

Detection of noroviruses in shellfish in the Netherlands [PDF]

International Journal of Food Microbiology, 2006
Shellfish from oyster farms in the Netherlands and imported from other European countries were examined for viral contamination. A method that allows sequence matching between noroviruses from human cases and shellfish was used. The samples of shellfish (n = 42) were analyzed using a semi-nested RT-PCR that had been optimized for detection of norovirus

Noroviruses in Archival Samples

Emerging Infectious Diseases, 2005
Application of recent techniques to detect current pathogens in archival effluent samples collected and concentrated in 1987 lead to the characterization of norovirus GGII.6 Seacroft, unrecognized until 1990 in a clinical sample. Retrospective studies will likely increase our knowledge about waterborne transmission of emerging pathogens.

Genetic Manipulation of Human Intestinal Enteroids Demonstrates the Necessity of a Functional Fucosyltransferase 2 Gene for Secretor-Dependent Human Norovirus Infection

mBio, 2020
Human noroviruses (HuNoVs) are the leading cause of nonbacterial gastroenteritis worldwide. Histo-blood group antigen (HBGA) expression is an important susceptibility factor for HuNoV infection based on controlled human infection models and epidemiologic

Microfluidic Biosensors for the Detection of Foodborne Pathogens: A Comprehensive Review

Food Science &Nutrition, Volume 14, Issue 11, November 2026.
Microfluidic biosensors offer several approaches to detecting foodborne pathogens in meat, milk, and fresh produce. The schematic shows food samples entering a lab‐on‐a‐chip platform, where microchannels direct them toward sensing regions. Pathogen‐associated signals can then be measured through alternative colorimetric, fluorescence, or digital ...

Detection and Quantification of Noroviruses in Shellfish [PDF]

Applied and Environmental Microbiology, 2009
ABSTRACT Noroviruses (NoVs) are the most common viral agents of acute gastroenteritis in humans, and high concentrations of NoVs are discharged into the environment. As these viruses are very resistant to inactivation, the sanitary consequences are contamination of food, including molluscan shellfish.

The Role of the Gut Microbiome in Resisting Norovirus Infection as Revealed by a Human Challenge Study

mBio, 2020
Norovirus infections take a heavy toll on worldwide public health. While progress has been made toward understanding host responses to infection, the role of the gut microbiome in determining infection outcome is unknown.
