Resumo: | The rhea (Rhea americana) is a South American bird of the ratite group and of the Rheiformes order. It has been exploited for economical purposes, as cattle alternative in European and South American countries. In Brazil, the State of Rio Grande do Sul is outstanding, in rhea rearing and it is in the process of implantation in the Country Northeasty Region. This work aims to describe the morphology of the blood cells in rheas. In this work ten rheas were used, regardless age and sex. Two ml of peripheral blood were collected by puncture of the brachial vein with disposable syringe. The samples here partially used to make extensions with Leishman stain. Seven types of nucleate cells have been observed through morphologic analysis on the light microscope. The erythrocyte revealed an elliptical form, with condensed nucleus of elliptical form; acidophilic cytoplasm. The thrombocyte revealed an elliptical form, with nucleus located in one of the polar regions; pale cytoplasm. As to the round-shaped leukocytes, within the granulocytes, the heterophils presented excentric, condensed, and lobulated nucleus; cytoplasm rich in fusiform salmon-colored granules. The eosinophils distinguish from the heterophils due to the round eosinophilic granules. The basophils stand out from the other granulocytes due to its large and central nucleus with round specific cytoplasmic and highly basophilic granules. Within the agranulocytes, the monocytes presented reniform nucleus, which is frequently central, with slack chromatin, with small areas of condensation; cytoplasm lightly basophilic and with vacuoles. The lymphocytes presented varies forms and sizes; large nucleus with slack chromatin with some nucleoli; scarce and basophilic cytoplasm. The cells of the peripheral blood of Rhea americana present on the light microscope morphology similar to the other birds which have already been studied. |

No Brasil, destaca-se o Rio Grande do Sul e, em fase inicial, o Nordeste. O presente estudo objetivou descrever a morfologia das células sangüíneas em ema. Neste trabalho foram utilizados dez exemplares, desconsiderando-se idade e sexo. Foram colhidos 3mL de sangue periférico por punção da veia braquial, com seringa descartável. As amostras foram utilizadas, em parte, na confecção de extensões coradas com Leishman. Feita a análise morfológica ao Microscópio de Luz, foram observados sete tipos celulares nucleados. O eritrócito mostrou-se elíptico, com núcleo geralmente condensado, de forma elíptica; citoplasma acidófilo. O trombócito apresentou-se elíptico, com núcleo localizado em um dos pólos; citoplasma pálido. Quanto aos leucócitos, de forma arredondada, entre os granulócitos os heterófilos apresentaram-se com núcleo excêntrico, condensado, lobulado; citoplasma rico em grânulos fusiformes de coloração salmão. Os eosinófilos distinguem-se dos heterófilos pelos grânulos arredondados eosinofílicos. Os basófilos destacam-se dos outros granulócitos pelo núcleo grande e central, com grânulos citoplasmáticos específicos arredondados e fortemente basofílicos. Entre os agranulócitos, os monócitos mostraram núcleo rineforme, freqüentemente central, de cromatina frouxa, com pequenas áreas de condensação; citoplasma levemente basofílico e com vacúolos. Os linfócitos apresentaram-se variados em forma e tamanho; núcleo grande com cromatina frouxa, com alguns nucléolos; citoplasma escasso e basofílico. As células do sangue periférico de Rhea americana apresentam ao Microscópio de Luz morfologia semelhante às demais aves já estudadas.Universidade de São Paulo.
