SUMMARY:

The genus Plasmodium spp. belongs to the order Haemospororida and can parasitize birds, reptiles, humans and other mammals. In birds, these parasites are known to cause avian malaria. Its transmission occurs by hematophagous dipterous vectors, of the Culicidae family. The infection can be subclinical, course with hematological changes such as anemia and leukocytosis and tissue pathologies, and can even cause sudden death, which will depend on the host's immunological capacity. Birds of the order Psittaciforme, such as Araras-canindé (Ara ararauna) and Papagaio-real (Amazona aestiva) are one of the main species apprehended in the IBAMA Screening Centers, as they are widely involved in the legal and illegal trade in wild animals due to its characteristics of sociability, intelligence and exuberant coloring. Currently, there are few studies that provide clinical and laboratory aspects related to Plasmodium infection in parrots, since most of the studies are directed at passerines and birds of production. The monitoring of the blood parameters of these species, in addition to being an important tool in the management and assessment of the health status of these populations, is also responsible for the diagnosis of avian malaria, through the direct visualization of gametocytes, trophozoites or schizonts within erythrocytes, thrombocytes and / or leukocytes in blood smears, as well as from the molecular diagnosis of the agent. In the present study, 43 birds, 19 Araras-canindé (Ara ararauna) and 24 Parrots (Amazona aestiva) from the seizure of trafficking, illegal breeding, or exchange of institutions destined to the Wild Animal Screening Center in Rio de Janeiro were examined. (CETAS), located in the municipality of Seropédica, were evaluated for the presence of Plasmodium spp. The presence and intensity of infection will be recorded through microscopic and molecular analyzes (Polymerase Chain Reaction), with the mitochondrial cytochrome b gene of the parasites, carried out for diagnostic confirmation and aid in the identification of species through genetic sequencing . The results will be associated with clinical and hematological factors in order to delimit clinical and laboratory aspects caused by the infection in these species. Avian plasmodia are considered to be important pathogens when introduced into bird populations with which they have not yet coevolved. Therefore, the importance of laboratory evaluation and diagnosis of this disease becomes evident, in order to detect and prevent the transmission of these protozoa, especially in the translocation of birds to regions where Plasmodium is not endemic, but that the conditions of transmission are favorable.
