Human Plasmodium knowlesi Infection Detected by Rapid Diagnostic Tests for Malaria
Figure 2. Phylogenetic tree constructed according to the neighbor-joining method based on A-type small subunit RNA sequences of several Plasmodium species (GenBank accession numbers are indicated). The sequence of the clinical isolate PkHHR-BPRC1 (in boldface) (GenBank accession no. FJ804768) clusters with all other P. knowlesi strains (indicated by Pk isolate numbers). Pfrag, P. fragile; Pinui, P. inui; Pcyn, P. cynomolgi; Pfalc, P. falciparum; Pmal, P. malariae. Scale bar indicates nucleotide substitutions per site.
