ABSTRACT:

Malaria remains the most important infection causing morbidity and mortality in the worldand is second only to mycobacterium tuberculosis as the single most important agent. Thiswork studiesthe density of plasmodiumfalciparum malaria parasite and ABO blood group among pregnant women inUniversity of Calabar Teaching hospital, Calabar. A total of 200 subjects (100 pregnant and 100 nonpregnantcontrols) were recruited for the study. Malaria parasite was detected by thick and thin filmmethod and standard tube method was used to determine the ABO blood groups. It was shown that theprevalence of blood group 0 is higher (p<0.050) in both pregnant (44.0%) and non-pregnant women(38.0%). The prevalence of malaria parasite was significantly higher (p<0.05) among the pregnantwomen (74.0%) than in the non-pregnant women (48.0%). A higher prevalence of malaria parasiteinfection {p.falciparum) was recorded among group 0 individual in both pregnant (90.90%) and nonpregnantwomen (63.20%) while lowest prevalence of malaria parasite infection was recorded amonggroup AB individuals in both pregnant (33.30%) and non-pregnant women (14.20%). It was observedthat malaria parasite density was significantly higher (p<0.05) among group A individual in bothpregnant (520±11.3 parasite/pl of blood) and non-pregnant women(320±9.8 parasite/pl of blood whilegroup 0 individuals in both pregnant and non-pregnant(306±8.9parasite/nl of blood)and (216±10.2
