Valores hematológicos em Bradypus variegatus provenientes de criatórios da região metropolitana de Belém.

Abstract

The blood tissue is made up of three main cell types: erythrocytes (red blood cells), leukocytes (white blood cells) and platelets (thrombocytes), suspended in a liquid called plasma phase. Apart from blood cells is composed of proteins, inorganic and organic substances, hormones and various components. The captive condition can also predispose to a number of conditions, making it necessary to carry out laboratory tests for the biomonitoring of animais. Among these tests, you can highlight the complete blood count. This is done to assess the general health, directing and deepening nature of pathophysiological situations and is useful as an aid to diagnosis and prognosis of certain diseases. The study describes the hematological values of three-toed sloth (Bradypus variegatus). For this study, we used eleven adult animais of both sexes (seven males and four females) at appropriate health conditions. Blood was collected from the cephalic vein and analyzed by the veterinary hematology counter. The studied haematological parameters included total count of red blood cells and white blood cells, hematocrit, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration of, differential leukocyte count and platelet count. In general, the values did not differ from few studies in existing literature. However, the platelet count was greater in males compared to females. The results can serve as a basis in determining interpretation as hematologic references to threetoed sloths in Pará Amazon.
