Two approaches were tested for final classification of these seven sample pairs: first, our proposed approach 1 is based on support from two out of three markers msp1, msp2, and glurp; second, our proposed approach 2 is based on markers msp1 and msp2 only, but defining as a decisive characteristic for a new infection a complete switch in allelic family between the pre- and posttreatment samples. This evidence concerns the gene ATAD1 and infection.
