A Mutation Is Making It Easier for Drug-Resistant Malaria to Spread
New findings shed light on what’s making the parasite less treatable using the drug that’s considered a first line of defense.
Scientists have identified a specific mutation in malaria parasites that is contributing to the spread of drug-resistant strains, according to research published in Nature Medicine. The mutations, located in a gene encoding a protein called px1, appear to be responsible for increased resistance to antimalarial drugs, particularly lumefantrine, which is a key component in the treatment of malaria.
The mutation, named PIN, was found to be rapidly spreading in Uganda, with prevalence reaching 84 percent in the north and 55 percent in the east by 2024. Researchers suggest that the PIN mutation has not undergone sufficient genetic recombination to spread more widely, indicating its rapid transmission. This mutation was first observed in a sample from 2008 and has since spread to multiple locations in Uganda.
The mutation was absent from the genetic databases between 2001 and 2015, suggesting it emerged relatively recently. The study emphasizes the urgent need for better surveillance systems to track the emergence and spread of drug-resistant malaria, as well as the development of new treatments to combat the growing problem.
