In April 1978, a Plasmodium falciparum infection was diagnosed in an adult male in Brazilian Amazonia. The parasite was resistant in vitro to chloroquine and resistent in vivo to pyrimethamine-sulfadoxine (FansidarR). The patient was successfully treated with minocycline (MinomaxR); however, his immune response to the parasite may have played an important role in the efficacy of the minocycline treatment.
