Targeted LC-MS/MS combined with multilocus DNA metabarcoding as a combinatory approach to determine the amount and the source of pyrrolizidine alkaloids contamination in popular cooking herbs, seeds, spices and leafy vegetables
multilocus DNA metabarcoding was performed on six highly contaminated samples, belonging to each subtype matrix, containing high levels of heliotrine type of PA / PANO s. Each time the analysis demonstrated ...
Very little influenza in the WHO European Region during the 2020/21 season, weeks 40 2020 to 8 2021.
2020/21 European seasonal influenza epidemic with just a few sporadic detections of all viral subtypes. This might possibly continue during the remainder of the influenza season. Service: Maladies virales ...
Progressive Control of Streptococcus agalactiae-Induced Innate Inflammatory Response Is Associated with Time Course Expression of MicroRNA-223 by Neutrophils.
chemokines and with a shift in infiltrating monocyte and macrophage subtypes toward a regulatory phenotype. Transient inhibition of miR-223 by an antagomir resulted in significant increase of CXCL2 expression ...
Towards a unified classification for human respiratory syncytial virus genotypes.
twenty-three genotypes within subtype HRSV-A and six genotypes within subtype HRSV-B. Applying the genotype criteria on subsampled data sets confirmed the robustness of the method. Health Topics: Respiratory ...
Phylogenetic Analysis of Belgian Small Ruminant Lentiviruses Supports Cross Species Virus Transmission and Identifies New Subtype B5 Strains.
nowadays consists out of 5 genotypes and 28 subtypes. In support of our national SRLV control program, we performed the genetic characterization of SRLV strains circulating in the Belgian sheep and goat ...
Alternating patterns of seasonal influenza activity in the WHO European Region following the 2009 pandemic, 2010-2018.
the study period. Influenza A virus subtypes alternated in dominance, except for 2013-2014 during which both cocirculated, and only one season (2017-2018) was B virus dominant. The median start week for ...
Detailed Evaluation of Data Analysis Tools for Subtyping of Bacterial Isolates Based on Whole Genome Sequencing: as a Proof of Concept.
public health laboratories depends on the availability of well-characterized and verified data analysis methods. However, multiple subtyping workflows are now often being used for a single organism, and ...
Study of the underlying mechanisms and consequences of pathogenicity differences between two in vitro selected G1-H9N2 clones originating from a single isolate.
Volume 50, Issue 1 (2019) Keywords: Animals Chickens Gene Expression Regulation Genome, Viral Hemagglutination Inhibition Tests Immunity, Innate In Vitro Techniques Influenza A Virus, H9N2 Subtype ...
Epidemiology and genotype 3 subtype dynamics of hepatitis E virus in Belgium, 2010 to 2017.
25 to 117 per year). Among 217 sequenced samples, 92.6% were genotype 3 (HEV-3), followed by 6.5% of genotype 1 and 0.9% of genotype 4. HEV-3 subtype viruses were mainly 3f, 3c and 3e. HEV-3f was the ...
Impact of the human papillomavirus status on the development of high-grade cervical intraepithelial neoplasia in women negative for intraepithelial lesions or malignancy at the baseline: A 9-year Swedish nested case-control follow-up study.
+ (OR, 9.44; 95% CI, 3.37-26.4). Other HPV types were not significantly associated with future CIN2 + in these younger women. For women 30 years old or older, both HPV-16/18 and other HPV subtypes ...
