Acute outbreak of porcine parvovirus infection in Mozambique.

Investigations were made to determine the causal agent of an acute outbreak of abortions recorded in a swine herd in Mozambique. Isolation of porcine parvovirus and demonstration of its specific antibodies accomplished by using enzyme-linked immunosorbent assay, haemagglutination inhibition and immunofluorescent tests, indicated that porcine parvovirus was the causal agent of the abortions. Other pathogenic agents causing reproductive failure, e.g. pseudorabies virus, Leptospira or Brucella species, were ruled out because investigations of these agents proved to be negative.
