B. Smid et al., ROD-SHAPED VIRUS-LIKE PARTICLES IN INTESTINAL CONTENTS OF PHEASANT CHICKS, Journal of veterinary medicine. Series B, 44(7), 1997, pp. 445-447
Rod-shaped virus-like particles (RSV), 55-85 nm in length and 18 nm in
diameter, with 5 to 10 segments sr helical turns, were demonstrated i
n the intestinal contents of young diarrhoeic pheasants by examination
of a fresh sample. The origin of RSV seems to be splitting tails of b
acteriophages.
