Introduction of WGS in food microbiology: advantages and challenges
implementation. As with the implementation of any method the validations of the WGS methodology requires a significant effort. Furthermore, the interpretation of the results should be done with care. Therefore, in ...
Surveillance of COVID-19 mortality in Belgium, epidemiology and methodology during 1st and 2nd wave (March 2020- 14 February 2021)
both for the total period and for the second wave. International comparison and ranking of COVID-19 crude mortality rates are misleading because of very heterogeneous methods used (e.g. case definition, ...
Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium
a subsequent quantification method using ultra-high performance liquid chromatography with diode array detection (UHPLC- DAD) was also successfully validated. Next, real-life illegal antimicrobial samples, ...
