Significant progress in our understanding of disease transmission in the wild can be made by examining variation in host–parasite–vector interactions after founder events of the host.
We describe avian malaria lineages and their seasonal prevalence in 2007-2008 in Saddlebacks from Mokoia Island, a source of birds for translocations, and investigate their pathogenicity.
Understanding the origin of invasive parasites and ecological transmission barriers on the distribution of mosquito-borne pathogens is enriched by molecular phylogenetic approaches now that large databases are becoming available.
A case of P. knowlesi malaria is described in a helicopter pilot from New Zealand, who became ill after returning from recurring visits to Malaysian Borneo in June 2010. His P. knowlesi infection was not detected using microscopic examination and a rapid diagnostic test for malaria, but was confirmed by both PCR (polymerase chain reaction) and sequence analysis showing homology with the ribosomal RNA gene for P. knowlesi.
