Transcript:

Researchers have found that the spleen plays a major role in the expression of Plasmodium vivax genes that are responsible for cytoadhesion, a process that escalates malaria infection. The identified spleen-dependant antigens were immunogenic in natural infections and provoked an immune response associated with clinical protection. This suggests that the spleen plays a major role in vivax infection, not only in the expression of proteins for cytoadherence but in that it may also produce antigens associated with clinical protection.

And scientists have developed a piece of Artificial Intelligence that can detect Plasmodium infection in the blood. The deep learning technology classifies Plasmodium falciparum infection in blood sample images with over 99% accuracy. The AI was made available through a mobile app and a website, allowing for both on and offline diagnoses. The technology has not yet been tested with other forms of Plasmodium infection; it’s unclear whether it can differentiate between them.
