In May 2013, Italy declared a national outbreak of hepatitis A, which also affected several foreign tourists who had recently visited the country. Molecular investigations identified some cases as infected with an identical strain A virus subgenotype IA. After additional European Union/European Economic Area (EU/EEA) countries reported locally acquired and travel-related associated same outbreak, international investigation team was convened, case definition issued harmonisation...
An optimized digital RT-PCR (RT-dPCR) assay for the detection of human norovirus GI and GII RNA was compared with ISO 15216-conform quantitative real-time (RT-qPCR) assays in an interlaboratory study (ILS) among eight laboratories. A duplex GI/GII RT-dPCR assay, based on 15216-oligonucleotides, used a Bio-Rad QX200 platform by six Adapted Qiagen Qiacuity or ThermoFisher QuantStudio 3D were one laboratory each. The ILS comprised quantification absence matrix oyster tissue samples. On average,...
ABSTRACT Common blue mussels ( Mytilus edulis ), horse Modiolus modiolus and flat oysters Ostrea ) obtained from various harvesting commercial production sites along the Norwegian coast were screened for presence of norovirus by a real-time reverse transcription (RT)-nested PCR assay possible indicators fecal contamination, i.e., F-specific RNA bacteriophages (F-RNA phages) plaque human adenoviruses circoviruses nested assay. The aims to obtain relevant information assessing risk...
Bovine coronavirus (BCoV) is a widely distributed pathogen, causing disease and economic losses in the cattle industry worldwide. Prevention of virus spread impeded by lack basic knowledge concerning viral shedding transmission potential individual animals. The aims study were to investigate duration quantity BCoV feces nasal secretions related clinical signs, presence blood tissues test hypothesis that seropositive calves are not infectious naïve in-contact three weeks after infection. A...
Samples collected every two weeks from the inlet and outlet of three sewage treatment plants were screened for presence noro-, rota-, astro-, adeno-, hepatitis A- circoviruses by (RT)-nested PCR, F-specific bacteriophages isolation in Escherichia coli Famp. Plants A B secondary plant C used primary treatment. Noroviruses detected 43%, 53% 24% samples 26%, 40% 21% A, C, respectively. Astroviruses, rotaviruses adenoviruses more prevalent. Adenoviruses 96% 94% samples, supporting potential...
ABSTRACT During the period from January 2000 to August 2005 a total of 204 outbreaks norovirus gastroenteritis were diagnosed at Norwegian Institute Public Health. A clear increase in activity was seen healthcare institutions during winter seasons. Polymerase sequence analysis strains 122 showed that 112 caused by GII (91.8%). Two variants study period—GIIb and GII.4—were predominant between September 2002, whereas GII.4 2002 onward. The highest 2002-2003 2004-2005 seasons with emergence new...
Bovine coronavirus (BCoV) is one of the major viral pathogens cattle, responsible for economic losses and causing a substantial impact on animal welfare. Several in vitro 2D models have been used to investigate BCoV infection its pathogenesis. However, 3D enteroids are likely be better model with which host-pathogen interactions. This study established bovine as an replication system BCoV, we compared expression selected genes during previously described HCT-8 cells. The were successfully...
There is growing evidence that plastic particles can accumulate microorganisms are pathogenic to humans or animals. In the current study, composition of plastispheres accumulated on polypropylene (PP), polyvinyl chloride (PVC), and high-density polyethylene (HDPE) pieces submerged in a river southeast Norway was characterized by 16S rRNA amplicon sequencing. Seasonal geographical effects bacterial plastisphere were identified, addition detection potential foodborne bacteria viruses as part...
Detection of viruses on berries is a challenging task, often hampered by the presence RT-qPCR inhibiting substances from berry juice. A direct extraction method for virus detection (murine norovirus and GA phage) frozen raspberries was previously published. We expanded (different types viruses) improved using MobiSpin S400 columns that filter nucleic acids based size-exclusion chromatography. While no inhibition detected in filtered RNA, unfiltered RNA needed 1:2 to more than 1:8 dilution...
