Orangutans Not Infected with Plasmodium vivax or P. cynomolgi, Indonesia

After orangutans in Indonesia were reported as infected with Plasmodium cynomolgi and P vivax, we conducted phylogenetic analyses of small subunit ribosomal RNA gene sequences of Plasmodium spp. We found that these orangutans are not hosts of P cynomolgi and P. vivax. Analysis of >= 1 genes is needed to identify Plasmodium spp. infecting orangutans.
