ABSTRACT
The aim of present study was to compare the efficiency of a commercial assay and two conventional methods for fecal concentration in detecting canine gastrointestinal parasites. Fecal samples from 254 dogs were processed by centrifugation-sedimentation (CS), centrifugation-flotation (CF) and a commercial assay for fecal concentration (TF-test). The following parasites were detected Ancylostoma (37.8%), Giardia (16.9%), Toxocara canis (8.7%), Trichuris vulpis (7.1%), Isospora (3.5%), and Sarcocystis (2.7%). The calculated analytical sensitivity indicated that CF was more accurate (P<0.01) in detecting Ancylostoma, T. canis, T. vulpis and Giardia infections. However, CF showed significantly higher sensitivity only for Ancylostoma, compared to the other two methods. The kappa index value of diagnostic agreement between TF-test and CF was high for T. canis (83%) and moderate for Giardia (72%) and Ancylostoma (63%). The advantages and limitations of each method were assessed for individual diagnosis and epidemiological investigation.
