The paralytic disease spread rapidly through a breeding colony as well as through a laboratory population causing about 95% mortality. This was the first recorded isolate of the virus 〔Reinganum, C., O'Loughlin, G. T. and Hogan, T. W. (1970) A nonoccluded virus of theoccations of dina oceanicus and T. commodus (Orthoptera: Gryllidae) Journal of Invertebrate Pathology 16(2): 214–220.〕 and is generally referred to as CrPVvic to distinguish it from subsequent isolates. ==Description== The spheroidal, non-enveloped virus particles of CrPV are about 27 nm diameter in negatively stained electron micrographs and contain a single piece of positive-sense ssRNA. The virion is composed of 4 capsid proteins with molecular masses generally reported to be 33, 31 and 30 kilodaltons with a minor VP4 protein of about 8 kDa. The particles resemble those of the mammalian picornaviruses but CrPV virions sediment at a faster rate (167 s) than poliovirus particles (158 s) in sucrose rate-zonal gradients and, in isopycnic neutral cesium chloride gradients, CrPV particles are denser than those of poliovirus (1.368 g/cm3 vs 1.340 g/cm3 respectively).〔Christian, P.D. and Scotti, P.D.
