Chronic obstructive pulmonar disease (COPD) of horses is an alergic alteration of lower respiratory tract with obstruction of aerovias and a mucupurolent bronchiolitis, developped by an amount of alergenics. It is disease of world wide distribution, being more common in warm countries where horses are feeded chiefly with hay & stay stabulated for long periods. In Chile it has been described being more ofter in springtime. In the present study 99 samples were analysed being of straw, mixed hay & alfalfa coming from 19 Chilean horse breeding grounds of the Valdivia & Osorno provinces in order to determinate the presence of thermophilic fungus & bacteria. The most isolated fungi were A. fumigatus, Mucor hiemalis & A. niger. Thermophilic bacteria were scarsely. Thermoactinomyces vulgaris & S. rectivirgula
