Virus and virus-like particles observed in the intestinal contents of the possum, Trichosurus vulpecula.

Intestinal contents derived from the Australian brush-tailed possum, Trichosurus vulpecula, were examined by negative stain electron microscopy for the presence of viruses. Out of 100 samples, 23 contained at least one type of vertebrate virus or virus-like particle. Adenovirus was identified in six samples, herpesvirus in two samples, coronavirus in four samples, and coronavirus-like particles in 14 samples. To date no viruses of the brush-tailed possum have been isolated in tissue culture but these results indicate that this species is probably host to several viral species.
