This study aims to compare the concentration of viable fungi, especially those of the genus Aspergillus in the respiratory tract of stabled horses with and without Recurrent Airway Obstruction (RAO). Thirty two housed horses from four equestrian centers in Brazil were included in the study. These animals were submitted to clinical examination and to a respiratory sample collection. They were categorized into two groups: healthy and RAO-affected horses. Samples obtained by tracheobronchial washes were evaluated for fungal microscopy, quantitative culture and Aspergillus spp. quantification. Eighteen healthy and 14 RAO-affected horses were studied. Fungi were more frequently recovered in the RAO group, in comparison to controls, for both fungal microscopy (P<0.0001), fungal culture (P<0.0001) and Aspergillus spp. quantitative culture (p=0.001). In conclusion, horses with RAO have significantly higher fungal load in the respiratory tract in comparison to healthy horses. The implications of these findings in terms of the pathogenesis of RAO deserve additional investigation.Keywords: Aspergillus, tracheobronchial washes, respiratory allergy RESUMO Este estudo objetivou comparar a concentração de fungos viáveis, especialmente do gênero Aspergillus, no trato respiratório de equinos estabulados com e sem obstrução recorrente das vias aéreas (ORVA
RESUMO Enterites são consideradas importantes causas de morbidade e mortalidade em potros neonatos. Dentre os agentes implicados, o coronavírus tem sido descrito como agente causador de enterocolite em equinos, podendo atuar como patógeno primário em potros jovens e imunocomprometidos. Este estudo relata doença entérica associada a coronavírus em 69 potros da raça Puro Sangue Inglês, criados em um haras no Município de Aceguá, RS. Os animais com idade entre 45 e 90 dias apresentavam diarreia, prostração e desidratação. A suspeita clínica do agente partiu da epidemiologia, descarte de causas não infecciosas, apresentação dos sinais clínicos, e exame de fezes negativo para agentes parasitários e bacterianos. A identificação do coronavírus foi realizada por microscopia eletrônica de varredura por contraste de fase nas amostras de fezes de seis potros que apresentavam quadro clínico de enterite.
