Description
Summary:ABSTRACT A case of a donkey attacked by Africanized honeybee is reported here with clinical signs of agitation, dehydration, congestion of the ocular mucous membranes, tongue edema, tachycardia and inspiratory dyspnea, and progression to death. At necropsy, diffuse, severe subcutaneous edema at face and cervical regions and severe diffuse pulmonary hyperemia with abundant edema without parenchymal collapse were observed. Microscopically, marked, diffuse deep dermis and panniculus carnosus edema and marked diffuse alveolar edema, with moderate population of eosinophils predominantly around larger caliber vessels were noted. The final diagnosis of anaphylactic shock was supported by history, clinical signs, and anatomic pathology findings. This is the first report of a honeybee attack with pulmonary eosinophilic infiltration in a mammal. RESUMO Descreve-se um caso de ataque de abelha africanizada em um burro, com sinais clínicos de agitação, desidratação, mucosas oculares congestas, edema de língua, taquicardia e dispneia inspiratória, com progressão e morte. Na necropsia, foram verificados edema subcutâneo difuso grave nas regiões de face e cervical, hiperemia pulmonar difusa grave com edema abundante e sem colapso do parênquima. Microscopicamente, foram observados edema marcado difuso na derme profunda e panículo carnoso e edema alveolar difuso acentuado, com população moderada de eosinófilos predominantemente em torno de vasos de maior calibre. O diagnóstico de choque anafilático foi baseado no histórico, em sinais clínicos e em achados anatomopatológicos. Este é o primeiro relato de ataque de abelhas com infiltração eosinofílica pulmonar em um mamífero.
