Fatal systemic necrotizing infections associated with a novel paramyxovirus, anaconda paramyxovirus, in green anaconda juveniles.

ABSTRACT: Beginning in July 2011, 31 green anaconda (Eunectes murinus) juveniles from an oceanarium in Hong Kong died over a 12-month period. Necropsy revealed at least two of the following features in 23 necropsies: dermatitis, severe pan-nephritis, and/or severe systemic multiorgan necrotizing inflammation. Histopathological examination revealed severe necrotizing inflammation in various organs, most prominently the kidneys. Electron microscopic examination of primary tissues revealed intralesional accumulations of viral nucleocapsids with diameters of 10 to 14 nm, typical of paramyxoviruses. Reverse transcription (RT)-PCR results were positive for paramyxovirus (viral loads of 2.33 × 10(4) to 1.05 × 10(8) copies/mg tissue) in specimens from anaconda juveniles that died but negative in specimens f
