Variation at position 86 of the <em>pfmdr1</em> gene in samples from an area with seasonal transmission in eastern Sudan

<p>Malaria is the most common parasitic disease of humans worldwide. A factor that aggravates the many attempts to control the epidemiologic malaria situation is the spreading of resistance against anti-malarial drugs. In this project the point mutation at position 86 of the <em>Plasmodium. </em><em>falciparum</em><em> </em>multidrug resistance gene (<em>pfmdr1</em>), which is thought to contribute to Chloroquine resistance, was analysed in 188 samples from a low transmission area in eastern Sudan, where malaria endemicity is seasonal. The patient group studied had asymptomatic and sub patent parasitemia that persisted during the transmission-free dry season, after being treated with Chloroquine. To differentiate between wild type and mutant genotypes, nested PCR and restriction fragment length polymorphism with the enzyme Apo1 was used. Out of 188 samples 79 (42%) were successfully analysed. Of those, 72% had parasites with mutant genotypes or where mixed infection. No conclusions on the relevance of the <em>pfmd</em><em>r</em><em>1</em> gene in the studied samples are made due to the many remaining gaps. However, eventual sources of error and previous findings in the study area are discussed.</p>
