A salting-out procedure (Miller et al. 1988) or a GeneMatrix Quick Blood DNA Purification Kit (EURx) was used for blood samples. For sex determination, we applied a method based on amplification of the CHD1 gene intron (Chromo-helicase-DNA-binding gene) using 2550F and 2718 R primers ...

population, the results would have been similar. Therefore, we split the total sample in a subsample and a holdout sample. Models developed by performing the same analysis procedure on the subsample were then tested on the holdout sample data. Table7shows that the patterns of complex conditions...

Step 1: Sampling—target enrichment Because SFIB might be present in the sample in very low numbers, it is necessary to enrich the bacteria. This is achieved by filtering a certain volume of water (milliliters to several liters) to concentrate the bacteria on a membrane filter. In the lab...
