ATAD1 and infection: A comparative analysis of distribution of the msp1 allelic families between single and multiple infections showed a statistically significant prevalence of MAD20 (χ2 = 18.1, p < 0.001) in patients suffering from multi-genotype infections whereas RO33 (χ2 = 29.1, p < 0.001) predominated in single infection (Fig. 2e).
