A group of scientists from Japan and Uganda have conducted a study of African Plasmodium malaria. It turned out that they
Like viruses and bacteria, eukaryotic parasites evolve, mutate, and become resistant to vaccines and drugs. In the late 1950s, this happened with Plasmodium falciparum, leading to outbreaks of malaria. Then the disease was treated with chloroquine, and 40 years later - with artemisinin.
A group of scientists from Japan and Uganda observedthe changes in the number and viability of plasmodia in the blood of several hundred malaria patients. The researchers then tested whether the increased half-life was actually related to drug resistance. After the biologists sequenced the genomes of the plasmodia and found seven different mutations in the gene kelch13which has been linked to artemisinin resistance.
Scientists are confident that even partial resistance toartemisinin can lead to disaster. If resistant plasmodia spread across Africa, which accounts for about 90% of the world's malaria cases, scientists will have to find new ways to combat Plasmodium. Otherwise, the world faces a new pandemic.
We will remind, in February 2014, the Ebola epidemic began in West Africa, and after the disease spread to the United States and Europe.
