Abstract:

Poxvirus was isolated from nodules on four immature grackles (Quiscalus sp.) collected in two residential areas of Victoria, Texas. All of the birds were emaciated and had nodules on the eyelids, bill, legs, toes, and areas of the skin on the wings, neck, and ventral abdomen. These pox nodules were extensive and probably interfered with both sight and flight. The preliminary diagnosis was confirmed by virus isolation, histopathology, and electron microscopy. Poxvirus was isolated on the chorioallantoic membrane of embryonated hen‘s eggs and in Muscovy duck embryo fibroblast cell culture. Phaenicia calliphoridae (blowfly) larvae were found in one of the pox nodules, raising the possibility of mechanical transmission of the virus by contaminated adult blowfiles. /// Se aisl?? virus de viruela a partir de n??dulos presentes en cuatro estorninos inmaduros (Quiscalus sp.) capturados en dos ?!reas residenciales de Victoria, Texas. Las cuatro aves estaban emaciadas y presentaron n??dulos en los p?!rpados, pico, patas, dedos, y algunas ?!reas de la piel de las alas, cuello, y regi??n inferior del abdomen. Estos n??dulos producidos por viruela eran extensos y probablemente interfirieron con la visi??n y el vuelo. El diagn??stico presuntivo fue confirmado mediante aislamiento viral, histopatolog?-a, y microscop?-a electr??nica. Se aisl?? el virus de viruela en la membrana corioalantoidea de huevos embrionados de gallina y en cultivos celulares de fibroblasto de embri??n de pato. Se encontraron larvas de mosca azul (Phaenicia calliphoridae) en uno de los n??dulos de viruela, increment?!ndose as?- la posibilidad de transmisi??n mec?!nica del virus mediante moscas adultas contaminadas.
