Sarcocystis spp. in birds of the order Anseriformes

Parasitology Research, 2004
Having studied 342 birds of 20 species of the order Anseriformes, we found Sarcocystis cysts in 100 individuals (29.2+/-2.5%) belonging to 15 species. One macrocyst and four microcysts types have been determined. By means of light microscopy, the morphology of cyst walls and merozoites have been examined and morphometric data are presented.

Fungal diseases of columbiformes and anseriformes

Veterinary Clinics of North America: Exotic Animal Practice, 2003
Because of the high incidence of aspergillosis, fungal disease is an important condition in the waterfowl. Although this is generally a disease of individual birds, epizootics have been reported when overwhelming spore loads are present. By contrast, the occurrence of fungal disease is quite sporadic in the pigeon. In both groups of birds, however, the
