Researchers have detected new strains of malaria-causing parasites in Ethiopia that are both resistant to current treatments and escape detection by common diagnostic tests, according to a new study.
The development could increase cases and deaths from malaria and makes eliminating the persistent disease an even greater challenge.
The authors detail their findings from a genomic surveillance study in the journal Nature Microbiology.
Already, scientists had found in Uganda, Tanzania, and Rwanda strains of the parasite that causes malaria that were resistant to most available antimalarial drugs; and separately, malaria parasites resistant to diagnostic tests had emerged in the Horn of Africa.
Those parasites have been spreading independently of one another, but the new study is the first published report to confirm the prevalence of this type of double-resistant malaria strain, says study author Jeffrey Bailey, an associate professor of translational research and pathology and laboratory medicine at Brown University.
“Now we’re essentially seeing the worst-case scenario: parasites with the mutation that make them resistant to treatment have also picked up the chromosomal deletions that make them invisible to the diagnostic tests,” he says.
“This means that it will be harder to detect people who are infected, and then when infected people are treated with antimalarial drugs, that may not work to stop them from spreading the disease.”
