The aim of this work was the diagnose of Aelurostrongylus abstrusus using histological techniques and lung tissue imprint, performing also morfometric characterization of the eggs and the morule of this nematode. When observed in histological sections, the mean size of the eggs (n=100) was 83,4 x 65,5mum, morphometric index (MI) 0,8, and the mean size of the morule (n=100) was 45,4 x 31,8mum, MI 0,7. When observed in the lung tissue imprint, the mean size of the eggs (n=100) was 105,3 x 93,6mum, MI 0,9 and the mean size of the morule (n=100) was 43,1 x 36,5mum, MI 0,8. The lung tissue imprint employed allowed the observation of the same parasitic forms visualized in histological sections. The results suggest the viability of using this technique for the pós-morte diagnostic of A. abstrusus.
