Summary
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 orBrucella species, were ruled out because investigations of these agents proved to be negative.
Résumé
Des recherches on été entreprises pour déterminer l'agent causal d'un foyer d'avortements dans un élevage de porcs en Mozambique. L'isolement d'un parvovirus porcin et la démonstration de l'existence d'anticorps spécifiques en utilisant les tests ELISA, d'inhibition de l'hemagglutination et d'immunofluorescence, indiquent que le parvovirus porcin est l'agent étiologique de ces avortements. On a pu éliminer l'implication d'autres agents pathogènes causant des accidents de reproduction, tels deLeptospira et desBrucella dont la recherche s'est averée négative.
Resumen
Se llevaron a cabo investigaciones para determinar el agente etiológico de un brote agudo de abortos en una explotación porcina de Mozambique. El aislamiento del virus de la parvovirosis porcina y la demostración de anticuerpos específicos para el mismo utilizando tests de ELISA, inhibición de la hemoaglutinación e inmunofluorescencia indicaron que el agente etiológico era el virus de la parvovirosis porcina. Otros microorganismos que pueden causar fracasos en la reproducción, tales como bacterias del géneroLeptospira oBrucella o el virus de la enfermedad de Ausjeszky fueron descartados al dar negativos los tests correspondientes.
