RESUMO

Blood exams are an indispensable tool in bird medicine. This study aimed at describing values and aspects of rheas' hematology, Rhea americana, as well as analyzing the morphology and morphometry of all blood cells. Fifty eight adult rheas of both sexes from two farms, one in Cachoeiro de Itapemirim, Espírito Santo State and the other in São Carlos, São Paulo State, were selected. Blood samples were taken and RBC count, PCV and Hb levels measured and used in hematimetric indexes calculations. The total and differentiated leukocyte counts, as well as the TPP and fibrinogen were determined. Erythrocytes, leukocytes and thrombocytes were identified and characterized morphologically. The values for the red series and hematimetric indexes were: RBC (2.81 ± 0.15 × 106/µL), PCV (44.20 ± 2.86%), Hb (12.12 ± 0.74 g/dL), MCV (15.75 ± 0.89 fL), MCH (43.18 ± 1.82 pg), MCHC (27.44 ± 0.80 g/dL); the values of white series were: WBC (12.072 ± 4116/µL), heterophils (64.10 ± 9.90%), eosinophils (2.05 ± 2.06%), monocytes (6.40 ± 2.99%), lymphocytes (26.93 ± 9.62%), basophils (0.52 ± 1.27%). One may conclude that on average, rheas' blood cells are larger than those of other birds, but these cells in smears cannot be differentiated only by their size. Besides rheas' leukocytes have different components and coloring as in other bird species, however, there are no components or staining aspects unique to the species.

Abstract Blood exams are an indispensable tool in bird medicine. This study aimed at describing values and aspects of rheas' hematology, Rhea americana, as well as analyzing the morphology and morphometry of all blood cells. Fifty eight adult rheas of both sexes from two farms, one in Cachoeiro de Itapemirim, Espírito Santo State and the other in São Carlos, São Paulo State, were selected.

The total and differentiated leukocyte counts, as well as the TPP and fibrinogen were determined. Erythrocytes, leukocytes and thrombocytes were identified and characterized morphologically. The values for the red series and hematimetric indexes were: RBC (2.81±0.15×106/μL), PCV (44.20±2.86%), Hb (12.12±0.74 g/dL), MCV (15.75±0.89 fL), MCH (43.18±1.82 pg), MCHC (27.44±0.80 g/dL); the values of white series were: WBC (12.072±4116/μL), heterophils (64.10±9.90%), eosinophils (2.05±2.06%), monocytes (6.40±2.99%), lymphocytes (26.93±9.62%), basophils (0.52±1.27%).

Resumo Exames de sangue são uma ferramenta indispensável na medicina de aves. Este estudo teve como objetivo descrever valores e aspectos da hematologia de emas, Rhea americana, bem como analisar a morfologia e morfometria de todas as células sanguíneas. Cinquenta e oito emas adultas de ambos os sexos de dois criatórios, um em Cachoeiro do Itapemirim, ES e o outro em São Carlos, SP foram selecionadas. Amostras de sangue foram coletadas e CTH, Ht e níveis de Hb foram mensurados e usados para o cálculo dos índices hematimétricos. A contagem total e diferencial de leucócitos, assim como, PPT e fibrinogênio foram determinados. Eritrócitos, leucócitos e trombócitos foram identificados e caracterizados morfologicamente. Os valores para série vermelha e índices hematimétricos foram: CTH (2,81±0,15×106/μL), Ht (44,20±2,86%), Hb (12,12±0,74 g/dL), VCM (15,75±0,89 fL), HCM (43,18±1,82 pg), CHCM (27,44±0,80 g/dL); os valores da série branca foram: CTL (12,072±4116/μL), heterófilos (64,10±9,90%), eosinófilos (2,05±2,06%), monócitos (6,40±2,99%), linfócitos (26,93±9,62%), basófilos (0,52±1,27%). Pode-se concluir que, na média, células sanguíneas de emas são maiores que as de outras aves, porém, não é possível diferenciar estas células em esfregaços somente pelo seu tamanho. Além disso, leucócitos de emas possuem diferentes componentes e coloração como acontece em outras espécies de aves, no entanto, não há nenhum componente ou aspectos tintoriais exclusivo para a espécie.
