ROSSINI V, Mario  e  GARCIA C, Gisela C. Morphologycal Description of Blood Cells of the Baba. Rev. Fac. Cienc. Vet. [online]. 2010, vol.51, n.2, pp.063-070. ISSN 0258-6576.

The Caiman crocodilus crocodiles is a species that has existed in nature for over 200 million years and has practically remained unchanged during this time. From the clinical pathological point of view, the morphological studies as well as the cellular dimensions are of great usefulness when describing and comparing hemograms. The aim of this investigation was to study the dimensions and morphology of blood cells. A sample of 100 animals from a wildlife reserve in Guaritico region, in the State of Apure, aged 2 to 5 years, was taken. Samples of whole blood using EDTA tubes were obtained and processed in the laboratory. Blood smears were stained with Giemsa and the morphological characteristics of each cellular group were analyzed. For measuring cell dimensions, randomly distributed holes were punched to acetate templates. Subsequently, photographs of the fields were taken and analysed using the Sigma Scan Pro 5 morphometric program.  Results show the size of the different cells: erythrocytes: 12,5-19,5 µm; heterophils: 11,3-18,5 mm; eosinophils: 11,5-14,9mm; basophils:  12,7-16,0 mm; lymphocyte: 6,5- 8,9 mm; monocytes: 9,4-14,6 mm, respectively and thrombocytes 9,3-12,0 mm. The morphology of these different blood cells coincides with that described for the Alligator mississippiensis, Caiman crocodilus yacare, Caiman crocodilus lacostris, the Agrionemys horsfieldi and other reptile species.
