Avian hematozoa of some birds from Tchad

A total of 389 birds of 32 species representing 14 families from Tchad were examined for blood parasites. Eighty-nine (22.9%) harbored infections of Haemoproteus (64%), Plasmodium (12.4%), Trypanosoma (1.1%), Atoxoplasma (=Lankesterella) (5.6%), and microfilaria (28.1%). Species of Leucocytozoon were not observed in the present study. The occurrence of the different genera differed markedly between bird families; members of the Ploceidae comprised 85% of the infected birds.
