Use of the FLOTAC technique as a new coproparasitological diagnostic method in aquatic mammals and comparison with traditional methods.

The inadequate choice of a diagnostic method or the option for techniques that have low sensitivity and specificity may limit the diagnosis of parasitic agents that affect aquatic mammals. The aim of this study was to evaluate the performance of the FLOTAC technique and compare it with three traditional methods (Willis, sedimentation and centrifugation- flotation) used in the diagnosis of gastrointestinal parasites in aquatic mammals. For this, 129 fecal samples from 12 species were collected.

[Comparison of nested-PCR with blood smear examination in detection of Ehrlichia canis and Anaplasma platys in dogs].

The clinical signs of Ehrlichia canis and Anaplasma platys infection are similar, and the diagnosis of these pathogens made by stained blood smears is poor due sensibility and specificity. On the other hand, the molecular diagnosis is highly sensitive and specific and nested-PCR have been optimized for accurate diagnosis these pathogens in dogs. At the veterinary teaching hospital, whole-blood samples with EDTA were obtained from 100 dogs and smears were made from blood samples for evaluation for intracellular parasites.
