The aim of the study was to determine whether the rapid diagnostic CPV Ag (VetExpert), CDV Ag (VetExpert)
and CDV/CAV Ag (VetExpert) tests are able to detect the presence of vaccine viruses in faeces and conjunctival
swabs (CDV) collected from dogs vaccinated against distemper, parvovirus and Rubarth’s disease. The
tested dogs were administered vaccines once, and then faeces and conjunctival sac swabs were collected from
all animals on days: 2, 5, 7, 10, 14, 20, 25 after the vaccination for molecular testing and to perform rapid
immunochromatographic tests for the detection of CPV, CDV and CAV antigens. The immunochromatographic
tests were not able to detect the presence of any of the tested pathogens during the 25-day observation period
in the vaccinated dogs, although CPV was detected in faeces by PCR up to 20 days after vaccination, and CDV
and CAV up to 14 days after vaccination. Summing up the results of our own research, it should be stated that
rapid immunochromatographic tests are not able to detect CPV, CDV and CAV vaccine viruses in the faeces
of animals subjected to vaccination, and in the case of CDV also in the conjunctival swabs, but they are an
excellent tool for detecting these pathogens in animals infected with field strains of these viruses and showing
clinical symptoms of the diseases.
