Resumo
The accuracy of the parasitological techniques of Willis, Hoffman-Pons-Janer or Lutz (HPLJ), Sheather and Faust was
evaluated in fecal samples from stray cats caught by the Zoonosis Control Center in Goiânia, Goiás, Brazil. These four
techniques were applied separately to analyze 154 fecal samples, and their accuracy was analyzed based on an evaluation
of their sensitivity, specificity, positive and negative predictive values, and Kappa index, resulting in the selection of the
Willis technique as the nominal gold standard. Of the 154 samples, 115 (74.68%) tested positive for intestinal parasites.
The analysis of the frequency of positivity indicated that the HPLJ technique detected 86.1% of the positive samples
and was the closest to the gold standard. The analysis of the accuracy of the techniques was evaluated using the most
prevalent parasites. The Sheather technique showed the highest accuracy in the detection of Ancylostomatidae, while
the Sheather and HPLJ techniques showed similar accuracies in the detection of Cystoisospora spp. when compared to
the gold standard. Lastly, the Faust technique showed the highest accuracy in the detection of Toxoplasma gondii when
compared to the gold standard. This study underscores the importance of combining parasitological techniques in the
diagnosis of intestinal parasites in cats.
