Abstract: Malaria remains the most important infection causing morbidity and mortality in the world and is second only to mycobacterium tuberculosis as the single most important agent. This work studies the density of plasmodium falciparum malaria parasite and ABO blood group among pregnant women in University of Calabar Teaching hospital, Calabar. A total of 200 subjects (100 pregnant and 100 non-pregnant controls) were recruited for the study. Malaria parasite was detected by thick and thin film method and standard tube method was used to determine the ABO blood groups. It was shown that the prevalence of blood group O 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 pregnant women (74.0%) than in the non-pregnant women (48.0%). A higher prevalence of malaria parasite infection (p.falciparum) was recorded among group O individual in both pregnant (90.90%) and non-pregnant women (63.20%) while lowest prevalence of malaria parasite infection was recorded among group AB individuals in both pregnant (33.30%) and non-pregnant women (14.20%). It was observed that malaria parasite density was significantly higher (p<0.05) among group A individual in both pregnant (52011.3 parasite/l of blood) and non-pregnant women(3209.8 parasite/l of blood while group O individuals in both pregnant and non-pregnant(3068.9parasite/l of blood)and (21610.2 parasite/l of blood)respectively had the lowest malaria parasite density. In conclusion, this study has shown that whereas blood group O has the highest tendency to have malaria attack, it has an inherent mechanism to attack the parasite (p. falciparum)   implying that group O individuals are relatively protected. Similarly, blood group A has relatively low prevalence, but has a higher tendency to suffer more when attacked.

 

Key words: Blood group, Malaria, parasite density.
