Utilização da hemaglutinação para mensurar título de parvovírus em fezes de cães naturalmente infectados

Abstract

The objective of the present study was to measure parvoviral titers eliminated in the feces of dogs naturally infected, using the viral haemagglutination method. The animals were treated at the Veterinary Hospital of the Federal University of Mato Grosso in the year 2016 and samples from 35 hospitalized animals with positive diagnosis for parvovirus through the immunochromatic test were collected daily and then submitted to the hemagglutination test. Data of anamnesis and laboratorial results forms were obtained from their respective clinical records. Of the 35 animals, 12 had detectable titers of parvovirus in the feces through haemagglutination. Approximately 50% of dogs presented viral titers after three or more days presenting clinical signs, which reaffirms the importance in make diagnosis in the beginning of clinical signs, since with a few days after the clinical presentation the amount of virus in the feces decreases significantly, in addition to using other diagnostic methods together to avoid false-negative results.
