Haematozoa

Haematozoa or Hematozoa is a general term that includes blood parasites, mainly protozoans. Well known examples include the malaria and trypanosoma parasites, but a large number of species are known to infect birds and are transmitted by arthropod vectors.[1]

Common Haematozoa

Trypanosoma brucei ssp.

This group of protozoan parasites includes two agents which cause African sleeping sickness, Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense. A third, morphologically identical species, Trypanosoma brucei brucei, infects domestic and wild animals but does not cause disease in humans because it is lysed by apolipoproetin L1 in the high-density lipoprotein fraction of human serum.[2]

The vector for these protozoans is the Tsetse Fly (Glossina spp.)
