A molecular study investigated co-infections of Plasmodium falciparum and Schistosoma species in Obi and Oju Local Government Areas using dried blood spots. Researchers extracted DNA and used nested polymerase chain reaction assays targeting specific genes, alongside merozoite surface protein 2 amplification and Illumina sequencing. Out of twenty-one sequenced Plasmodium falciparum samples, seven were fully assembled for genetic diversity analysis. Sequence and phylogenetic analyses revealed genomic variation in Plasmodium falciparum, suggesting that evolving resistance traits might facilitate persistent co-infections. The investigation confirmed a notable prevalence of concurrent infections between the two parasites. The findings emphasize the necessity of integrated molecular surveillance, tailored treatment protocols, and water, sanitation, and hygiene interventions to manage parasitic transmission in endemic areas, while highlighting the utility of polymerase chain reaction tools for early clinical detection.
Co-infections of malaria and schistosomiasis present significant public health challenges in endemic regions. Identifying genetic variations in circulating parasites helps researchers understand how resistance evolves and why infections persist. Employing sensitive molecular surveillance tools enables healthcare authorities to design more precise treatments and targeted sanitation programmes, ultimately improving community health outcomes where both parasitic diseases are widespread.
This research represents early-stage surveillance and molecular profiling rather than a commercial product. The protocol and genetic findings could inform molecular diagnostic kit manufacturers and public health organisations tracking parasite diversity and resistance markers. Any transition into commercial diagnostic assays or standardized monitoring platforms remains at an early stage, requiring expanded validation on larger clinical cohorts and operational development for routine field deployment.

This study employed a molecular approach to detect, identify, and analyze Plasmodium falciparum and Schistosoma species co-infection using dried blood spots collected from individuals in Obi and Oju Local Government Areas.DNA was extracted using the QIAamp DNA Mini Kit protocol, followed by nested Polymerase Chain Reaction (PCR) targeting the 18S rRNA gene for Plasmodium falciparum and species-specific primers for Schistosoma.PCR-positive samples were further subjected to amplification of the merozoite surface protein 2 (MSP2) gene, and selected amplicons underwent sequencing using the Illumina platform.Sequence analysis and phylogenetic reconstruction revealed genomic variation in P. falciparum, which may contribute to the persistence of coinfections due to evolving resistance traits.Among 21 sequenced P. falciparum samples, only 7 were fully assembled and analyzed for genetic diversity.The study confirmed a notable prevalence of co-infection and highlighted the role of genomic variation in the resilience of these parasites.Findings underscore the necessity for integrated molecular surveillance, targeted treatment strategies, and improved public health interventions addressing water, sanitation, and hygiene (WASH) in endemic areas.Molecular diagnostic tools such as PCR remain crucial for early detection and control of parasitic diseases.
