Abstrakt: Grey crowned cranes (Balearica regulorum) have been facing significant and long-term population declines in East Africa. Studies of Haemosporidian infections are essential to gain insight into pathogenic threats and help infer vector-host relationships, resolve parasite relationships, and support conservation efforts. As part of a program to reintroduce captive cranes in Rwanda back to their natural habitats, through health checks and initial microscopic examination, 120 grey crowned cranes were selected under suspicion of harboring Haemosporidian infections following initial peripheral blood smear examinations. Of these, 104 were infected with Haemoproteus and 3 were coinfected with Leucocytozoon as detected by PCR and microscopy. Sequencing allowed us to identify 2 distinct unreported lineages of Haemoproteus antigonis and one lineage of Leucocytozoon in the subspecies of Grey Crowned Cranes endemic to East Africa, B. r. gibbericeps. Molecularly, our two lineages of Haemoproteus antigonis differ by 32 base pairs and matched with about 95 percent identity to previously reported sequences of H. antigonis found in other species of cranes. No visible morphologic differences were found when compared to images of H. antigonis from previous studies. Our work demonstrates not only a need for increased testing within the family Gruidae, but also to investigate the possibility of cryptic speciation within the morphospecies Haemoproteus antigonis.
