The species Aspergillus spp. Is the main cause of respiratory mycosis with high mortality and morbidity, reducing the poultry farmer’s profits. The objective of this study was to isolate and identify the presence of the main fungal strains in a commercial farm of replacement pullets. 60 pullets were sampled from the reception in the farm (day one) for three weeks (180 birds) and 15 of those housed in the shed at day eight of age (180 birds). A 1cm portion of lung was seeded on potato dextrose agar. The fungi were identified by morphometry. The data was analyzed by SPSS for Windows. They isolated and identified Aspergillus fumigatus, A. flavus, A. niger and the presence of Zygomycetes spp. (P>0.05). Mortality due to aspergillosis occupied the second place (P<0.01). It is concluded that in addition to aspergillosis zygomycosis is the cause of respiratory problems and mortality in farms.
