Results will be interpreted as follows: recrudescence (for each marker (msp1, msp2 and glurp), at least one identical length polymorphism is found in the sample collected at day 0 and on the day of recurrent parasitemia); new infection (for at least one marker, length polymorphism is different between the sample collected at day 0 and that on the day of recurrent parasitemia); indeterminate (samples that failed to produce a result due to an inability to amplify DNA at day 0 and/or on the day of recurrent parasitemia). The gene discussed is ATAD1; the disease is infection.
