Unit Response and Costs in Web Versus Face-To-Face Data Collection: Comparison of Two Cross-sectional Health Surveys.
groups the difference between web and F2F was more limited. Web data collection has a considerable cost advantage. It is therefore worth experimenting with adaptive mixed-mode designs to optimize financial ...
A High-Throughput Yellow Fever Neutralization Assay.
efficacy in population-wide studies. All of this requires serological assays that can process a large number of samples in a highly standardized format. Albeit being laborious, time-consuming, and limited in ...
Differential responses of eubacterial, Mycobacterium, and Sphingomonas communities in polycyclic aromatic hydrocarbon (PAH)-contaminated soil to artificially induced changes in PAH profile.
developed into a more diverse community but finally decreased in size below the detection limit. Mycobacterium in that soil never increased to a detectable size, while the eubacterial community became ...
Dietary silver nanoparticles can disturb the gut microbiota in mice.
metabolic and inflammatory diseases, such as obesity. It also highlights that Ag NP aging in food, and more specifically sulfidation, can reduce the effects of Ag NP on the microbiota by limiting the release ...
A general approach to identify low-frequency variants within influenza samples collected during routine surveillance.
% were established as detection limits. Secondly, a subset of 59 retained influenza A (H3N2) samples from the 2016-2017 Belgian influenza season was composed. Thirdly, as a proof of concept for the added ...
Optimization and Application of a Multiplex Digital PCR Assay for the Detection of SARS-CoV-2 Variants of Concern in Belgian Influent Wastewater.
low concentrations of SARS-CoV-2 RNA in IWW since the limit of detection of the different targets ranged between 0.3 and 2.9 copies/µL. This developed WBE approach was applied to IWW samples originating ...
Energy Drink Consumption among Adolescents Attending Schools in Lubumbashi, Democratic Republic of Congo.
and education on ED s are necessary to limit the regular consumption of ED s among adolescents. Health Topics: Food consumption and food safety Consommation et sécurité alimentaires Voedselconsumptie ...
Vaccine effectiveness against infection and onwards transmission of COVID-19: Analysis of Belgian contact tracing data, January-June 2021.
number of viral-vector vaccines included limited interpretability. Health Topics: Post-authorisation surveillance of COVID-19 vaccines Post-autorisatie surveillance van COVID-19 vaccins Surveillance ...
A TaqMan probe-based multiplex real-time PCR method for the specific detection of wild type lumpy skin disease virus with beta-actin as internal amplification control.
DNA copies, the limit of detection for WT LSDV was 12.6 DNA copies per reaction. The inter-assay CV was 0.04% for WT LSDV and 0.13% for beta-actin. The method can confirm diagnosis in suspect cases ...
Development and evaluation of a core genome multilocus sequence typing scheme for Paenibacillus larvae, the deadly American foulbrood pathogen of honeybees.
this approach has limited resolution, especially for epidemiological studies. As the cost of whole-genome sequencing has decreased and as it becomes increasingly available to most laboratories, an ...
