Abstract

To determine the frequency of co-infections with Plasmodium species in southern Myanmar, we investigated the prevalence of P. knowlesi. More than 20% of patients with malaria had P. knowlesi infection, which occurred predominantly as a co-infection with either P. falciparum or P. vivax.

Phylogenetic analysis of A-type and S-type 18S small subunit (SSU) rRNA gene sequences of Plasmodium spp., Myanmar, 2008. Fragments of 18S SSU rRNA gene sequences of samples were analyzed by aligning with published homologous sequences of P. falciparum, P. vivax, and P. knowlesi. A phylogenetic tree was constructed on the basis of similarities by using MEGA version 4.1 (13). Novel sequences identified in this study are indicated in boldface. Scale bar indicates nucleotide substitutions per site.
