The diagnostic effectiveness of two parasitological tests in feces, the simple direct method and the flotation method, were compared against post-mortem findings utilizing samples collected from 180 street dogs euthanized during a rabies control campaign. Post-mortem examination revealed that 27% of the animals were infected with tapeworm (Toxocara canis and Toxascaris leonina), but the simple direct method and the flotation method only indicated 12.7% (0.47 + 0.07 sensibility) and 17.2 % (0.63 + 0.07 sensibility), respectively. Kappa and McNemar analysis showed statistical differences and an agreement index of 0.68 ± 0.07 between both tests. The results produced by the simple direct and flotation methods were weakly and moderately proportional to the post-mortem findings, indicating that the flotation method is more efficient than the simple direct method, although both methods may produce negative results for cases with a low level of parasitism.
