Distribution of malaria-specific IgG and IgM antibodies in response to Plasmodium falciparum infection in Fulani and Dogon children. Blood plasma levels from 77 children were analysed for malaria-specific IgG (A) and IgM (B) antibodies. The children were subdivided in terms of ethnicity and with regards to being infected or not according to slide positivity to malaria; i.e. uninfected Dogon (n = 20), infected Dogon (n = 20), uninfected Fulani (n = 23) and infected Fulani (n = 14). The boxes represent the values between 25% and 75% quartile and the line indicates the median. The whiskers indicate the 10% and 90% percentiles. Statistical analysis was done by Mann-Whitney U test.
