Mariama Souffou from MERIT - UMR_D 261 reveals an immune protection mechanism against malaria related to toxoplasmosis in Benin

Mariama Souffou, a researcher at the Institute for Research and Development, has highlighted that pregnant women seropositive for Toxoplasma gondii have fewer malaria infections by Plasmodium falciparum in Benin. This discovery, stemming from a sero-epidemiological study, paves the way for strategic opportunities for the development of polyvalent vaccines against these parasitic co-infections.

Research on parasitic co-infections is crucial for public health in West Africa. Mariama Souffou studied the interactions between Toxoplasma gondii and Plasmodium falciparum, two endemic parasites. Malaria poses a major challenge, while toxoplasmosis, often overlooked, presents significant risks, particularly for pregnant women. These interactions raise questions about their impact on the health of vulnerable populations.

The study results show that pregnant women seropositive for T. gondii have a reduced prevalence of malaria infections. This finding suggests an immune protection mechanism that could be exploited to develop prevention strategies. The analysis of sero-epidemiological data established a significant link between toxoplasmosis and reduced susceptibility to malaria.

The implications of this research are strategic for public health. The development of polyvalent vaccines targeting Toxoplasma gondii and Plasmodium falciparum could improve the health of vulnerable populations, especially pregnant women. Policymakers should consider these results to guide health policies and invest in innovative solutions to address co-infections.

« « Pregnant women seropositive for Toxoplasma gondii have fewer malaria infections, suggesting an immune protection mechanism to explore, » says Mariama Souffou. »

« « This research highlights opportunities for access to knowledge that can influence strategic decisions in public health in West Africa, » emphasizes the Lektaris team. »
