Parâmetros hematológicos, bioquímicos e eletrocardiográficos de Iguana iguana (reptilia, squamata, iguanidae) de vida livre, na região urbana de Santarém, Pará, Brasil.

Abstract

The objective of this study is to carry out the hematological, biochemical, hemoparasitic and electrocardiographic study of I. iguana in the municipality of Santarém, Pará, Brazil. In the present study, 36 green iguanas captured on the external premises of a specific property were used. As hematological, biochemical and hemoparasitic analyzes were performed with a blood sample collected by jugular venipuncture in a tube with anticoagulant containing sodium heparin. The blood count was performed by counting cells in the Neubauer chamber using the 0.01% Toluidine Blue method. As biochemical analyzes were performed with heparinized plasma and using a dry biochemistry methodology. Hematological and biochemical values were compared in relation to seasonality in two extremes, Amazonian summer and winter. A survey of hemoparasites was carried out on blood strains stained with hematological. Electrocardiographic parameters were performed by placing the electrodes on the patient's chest near the forelimbs. Among the hematological results, there were statistical differences between the sexes for the erythrocyte values, these being the largest in males, and among the statistics, there were statistical differences in the erythrocyte and hemoglobin values, the largest being in the hot season. In the biochemical values, there were statistically significant differences between the sexes in the values of triglycerides, very low density lipoproteins (VLDL), calcium and phosphorus, these being higher in children, and between seasonal statistics in the values of phosphorus, phosphorus, total proteins and albumin, which are higher during the hot season. Onda SV was observed with great difficulty in some cases and was absent in 9 iguanas. All iguanas presented sinus rhythm, P wave followed by the QRS complex. All P, R, QRS and T waves were observed positive. Q wave and S wave were absent or less than 0.05mV in 20 iguanas. Hematological, biochemical and electrocardiographic values were selected in I. Iguana in the tropical region, the values were also selected for the hot season and for the dry season. There is a presence of hemoparasites in these animals, however, an infection does not demonstrate significant changes in the values of erythrocytes, leukocytes and thrombocytes. This study provided the electrocardiographic parameters in free-living iguana and tropical climate, with no difference between seasons.
