Summary
The first recorded isolation of porcine parvovirus (PPV) in Panama is described. The outbreaks of PPV disease were characterised by a high prevalence of mummified foetuses, stillborn and weak pigs and a common source of exposure. Diagnosis was based on virus isolation and by demonstrating viral antigen in lungs of affected foetuses. Six farms in four different provinces were involved. Rapid control of the epizootic was achieved through the use of an inactivated PPV vaccine in the affected farms.
Résumé
Pour la première fois l'isolation d'un parvovirus porcin au Panama est décrite. Les foyers de cette affection ont été caractérisés par la présence, en grand nombre, de foetus momifiés, de porcelets mort-nés ou très fragiles et une origine commune de contamination. Le diagnostic a reposé sur l'isolement du virus et la reconnaissance de l'antigène viral dans les poumons des foetus. Six élevages dans quatre provinces différentes ont été touchés. L'épizootie a été rapidement maîtrisée grâce à l'emploi d'un vaccin parvovirus porcin dans les élevages atteints.
Resumen
Se describe el primer aislamiento de parvovirus porcino (PVP) en Panamá. Los brotes se caracterizaron por una prevalencia alta de fetos momificados, mortinatos y recién nacidos débiles; todos tuvieron una fuente común de exposición. El diagóstico se basó en el aislamiento del virus y en la demostración del antígeno viral en pulmones de los fetos abortados. Seis porquerizas en cuatro provincias differentes estuvieron involucradas. La enfermedad se controló rápidamente en las granjas problema, mediante el use de una vacuna inactivada de PVP.
