A paramyxovirus of serotype 3 isolated from African and Australian finches.
Two virus isolates were obtained from exotic finches (Ortygospiza atricollis and Poephila cincta) suffering from apathy, diarrhea, conjunctivitis, and dysphagia. The isolates were identified as paramyxoviruses based on their multiplication characteristics in embryonating chicken eggs, chicken embryo fibroblasts, and chicken embryo kidney cell cultures, on morphology upon electron microscopy, and on other biological properties. Both isolates were serologically related to the reference strain of the paramyxovirus serotype 3. Intravenous infection of 42-day-old chicks resulted in no clinical signs, but intracerebral infection of 1-day-old chicks resulted in mortality and intracerebral pathogenicity indices of 0.25 to 0.35. Of five finches from various species inoculated with isolate 840/85, three remained clinically healthy through 6 weeks, but two died: one (Poephila cincta) 5 days postinoculation after showing nervous distress, and the other (Amandava amandava) suddenly 42 days postinoculation.
