Malaria in Farmed Ungulates: an Exciting New System for Comparative Parasitology

A wide array of vertebrates can serve as the intermediate hosts to malaria parasites (Apicomplexa: Haemosporida), such as birds, lizards, and several groups of mammals, including primates, bats, rodents, and ungulates. The latter group of hosts has not been intensively studied since early descriptions of a small set of taxa were published, but new reports of these parasites in both expected and new hosts have recently been published. A new paper reports the presence of Plasmodium odocoilei in farmed white-tailed deer in Florida, particularly in animals less than 1 year old, and provides evidence that the parasites may contribute to mortality in fawns. That paper opens new opportunities to study the malaria parasite-mammal interface in North America.
