Survival and Inactivation by Advanced Oxidative Process of Foodborne Viruses in Model Low-Moisture Foods

Neda Nasheri, Jennifer Harlow, Angela Chen, Forest Dussault, Nathalie Corneau, Sabah Bidawid,

Abstract Enteric viruses, such as human norovirus (NoV) and hepatitis A virus (HAV), are the major causes of foodborne illnesses worldwide. These viruses are shed in high numbers, have low infectious dose, and may remain infectious for weeks in the environment and food. While numerous viral survival studies have been ... Read more >>

Evaluation of Bead-Based Assays for the Isolation of Foodborne Viruses from Low-Moisture Foods.

Neda Nasheri, Jennifer Harlow, Angela Chen, Nathalie Corneau, Sabah Bidawid,

ABSTRACT:Foodborne viruses such as norovirus and hepatitis A virus (HAV) are highly transmissible, persistent in the environment, and resistant to many conventional inactivation methods. Foods can become contaminated with these viruses either at the source of harvest or during food handling and processing. Multiple lines of evidence suggest that foodborne ... Read more >>

Genetic characterization of norovirus GII.4 variants circulating in Canada using a metagenomic technique.

Nicholas Petronella, Jennifer Ronholm, Menka Suresh, Jennifer Harlow, Oksana Mykytczuk, Nathalie Corneau, Sabah Bidawid, Neda Nasheri,

BACKGROUND:Human norovirus is the leading cause of viral gastroenteritis globally, and the GII.4 has been the most predominant genotype for decades. This genotype has numerous variants that have caused repeated epidemics worldwide. However, the molecular evolutionary signatures among the GII.4 variants have not been elucidated throughout the viral genome. METHOD:A ... Read more >>

Characterization of the Genomic Diversity of Norovirus in Linked Patients Using a Metagenomic Deep Sequencing Approach.

Neda Nasheri, Nicholas Petronella, Jennifer Ronholm, Sabah Bidawid, Nathalie Corneau,

Norovirus (NoV) is the leading cause of gastroenteritis worldwide. A robust cell culture system does not exist for NoV and therefore detailed characterization of outbreak and sporadic strains relies on molecular techniques. In this study, we employed a metagenomic approach that uses non-specific amplification followed by next-generation sequencing to whole ... Read more >>

Prevalence and Molecular Characterization of the Hepatitis E Virus in Retail Pork Products Marketed in Canada.

Oksana Mykytczuk, Jennifer Harlow, Sabah Bidawid, Nathalie Corneau, Neda Nasheri,

Infection with the hepatitis E virus (HEV) is very common worldwide. HEV causes acute viral hepatitis with approximately 20 million cases per year. While HEV genotypes 1 and 2 cause large waterborne and foodborne outbreaks with a significant mortality in developing countries, genotypes 3 and 4 are more prevalent in ... Read more >>

Nanolitre real-time PCR detection of bacterial, parasitic, and viral agents from patients with diarrhoea in Nunavut, Canada.

David M Goldfarb, Brent Dixon, Ioana Moldovan, Nicholas Barrowman, Kirsten Mattison, Chad Zentner, Maureen Baikie, Sabah Bidawid, Francis Chan, Robert Slinger,

Little is known about the microbiology of diarrhoeal disease in Canada's Arctic regions. There are a number of limitations of conventional microbiology testing techniques for diarrhoeal pathogens, and these may be further compromised in the Arctic, given the often long distances for specimen transport.To develop a novel multiple-target nanolitre real-time ...

Rotaviruses from Canadian farm samples.

Safaa Lamhoujeb, Angela Cook, Frank Pollari, Sabah Bidawid, Jeff Farber, Kirsten Mattison,

Animal rotavirus (RoV) strains detected in Canadian swine and dairy cattle farms were characterized by sequence analysis of viral protein 4 (VP4), VP6, VP7 and non-structural protein 4 segments from 15 RoV strains. Some porcine strains were found to contain a mixture of segments typical of human and animal viruses. ... Read more >>

Development and validation of a microarray for the confirmation and typing of norovirus RT-PCR products.

Kirsten Mattison, Nathalie Corneau, Ingvild Berg, Albert Bosch, Erwin Duizer, Ion GutiƩrrez-Aguirre, Yvan L'homme, Yalda Lucero, Zhiyao Luo, Alexander Martyres, Mette Myrmel, Miguel O'Ryan, Franco Pagotto, Daisuke Sano, Sanela Svraka, Ulises Urzua, Sabah Bidawid,

Noroviruses are implicated in many worldwide institutional, food and waterborne outbreaks each year. Genetic typing of isolates is valuable for monitoring outbreak spread as well as variation in circulating strains. Microarrays have the potential to provide rapid genotype information for norovirus samples. The NoroChip v3.0 provides an oligonucleotide hybridization platform ... Read more >>

Molecular detection and characterization of noroviruses from children in Botswana.

Kirsten Mattison, Teresa K Sebunya, Anu Shukla, Lebani N Noliwe, Sabah Bidawid,

Stool specimens were collected from 100 children in Botswana. RT-PCR analysis detected noroviruses (NoVs) in 24% of samples tested. Genogroup I and genogroup II strains were identified. There was no association between NoV detection and age or gender. This study is the first indication that NoVs circulate widely in Botswana. ... Read more >>

Development of a DNA microarray for the simultaneous detection and genotyping of noroviruses.

Franco Pagotto, Nathalie Corneau, Kirsten Mattison, Sabah Bidawid,

Current methods for detecting and genotyping noroviruses focus on the use of reverse transcriptase (RT)-mediated PCR. A major drawback of this approach is that short target RT-PCR products do not always encompass sequences that can be compared among research laboratories, resulting in difficulties for molecular epidemiology. We describe the use ... Read more >>

Human noroviruses in swine and cattle.

Kirsten Mattison, Anu Shukla, Angela Cook, Frank Pollari, Robert Friendship, David Kelton, Sabah Bidawid, Jeffrey M Farber,

Human noroviruses are the predominant cause of foodborne gastroenteritis worldwide. Strains of norovirus also exist that are uniquely associated with animals; their contribution to the incidence of human illness remains unclear. We tested animal fecal samples and identified GIII (bovine), GII.18 (swine), and GII.4 (human) norovirus sequences, demonstrating for the ... Read more >>

Foodborne spread of hepatitis A: Recent studies on virus survival, transfer and inactivation.

S A Sattar, T Jason, S Bidawid, J Farber,

Hepatitis A virus (HAV) is responsible for considerable morbidity and economic losses worldwide, and is the only reportable, foodborne viral pathogen in Canada. Outbreaks caused by it occur more frequently in settings such as hospitals, daycare centres, schools, and in association with foods and food service establishments. In recent years, ... Read more >>
