|Title:||A New Eimerian Species (apicomplexa: Eimeriidae) From The Blue-fronted Amazon Parrot Amazona Aestiva L. (aves: Psittacidae) In Brazil|
|Abstract:||The Neotropical psittacine species Amazona aestiva, commonly known as the blue-fronted Amazon, is one of the most common and best-known psittacine birds kept as a pet worldwide. However, very little is known about the diseases or parasites of these birds. In this study, we describe a new species, Eimeria aestivae, associated with these parrots. The new species is characterized by: ovoid smooth oocysts (n ?=? 60), 36.8 (33.241.5) × 23.7 (21.725.7) m, length/width ratio ?=? 1.55; polar granule present; ellipsoidal sporocysts (n ?=? 25), 19.8 (17.521.6) × 9.3 (8.39.9) m; Stieda, sub-Stieda body, and sporocyst residuum present. Sporozoites (n ?=? 20), 2 per sporocyst, elongate and curved, 17.6 (15.819.2) × 3.8 (3.24.8) m; each with 2 refractile bodies. The oocysts of the other 2 eimerian species described for Amazona are larger than those of the presented species, but they all seem to be closely related because of some similarities among them. © 2011 American Society of Parasitologists.|
