title: The seroreactivity against Pf155 (RESA) antigen in villagers from a mesoendemic area in Somalia.
abstract: Pf155 (RESA), a malaria antigen in the membrane of infected red cells, was recently identified as a possible future malaria vaccine candidate. In this study the seroreactivities against this antigen were compared with those against crude parasitic antigens in 195 subjects from a Somali village with mesoendemic malaria. The seroreactivities were determined with immunofluorescence. With age, there was an increased seroreactivity to both Pf155 and the crude parasitic antigens. However, the acquisition of seroreactivity was much slower against Pf155. Hence in the age group 15-24 years, only half of the subjects had detectable antibodies against Pf155.
