Níveis de anticorpos contra o vírus da cinomose canina e o parvovírus canino em cães não vacinados e vacinados / Antibodies levels against canine distemper virus and canine parvovirus in vaccinated and unvaccinated dogs

ABSTRACT

Antibody titres to canine distemper virus (CDV) and canine parvovirus (CPV) were measured in 132 dogs: 80 had been vaccinated at least once, 22 had not been vaccinated, and 30 had unknown vaccination history. Serum antibody titers were measured by means of serum neutralization (CDV) or hemagglutination inhibition (CPV). Serum CDV titers >20 and serum CPV titers >80 were considered protective. Protective antibodies to CDV were present in 40.1 percent of the population: 39.8 percent of the vaccinated dogs, 31.8 percent unvaccinated, and in 46.6 percent of the dogs with unknown vaccination history. Protective antibodies to CPV were present in 90.9 percent of the dogs: 93.7 percent of the vaccinated dogs, 90.9 percent of the unvaccinated, and 83.3 percent of the dogs with unknown vaccination history.
