RNA viruses Viruses having RNA genomes.

roan antelope herpesvirus Synonym for Hippotragine herpesvirus 1.

Rochambeau virus (RBUV) A tentative species in the genus Lyssavirus. Isolated from mosquitoes, Coquillettidia albicosta, in French Guiana in 1973. Not reported to cause disease in humans.

Rocio virus (ROCV) A strain of Ilheus virus in the genus Flavivirus, isolated by i.c. injection into newborn mice from the brain of a patient who died of encephalitis in Sao Paulo, Brazil. Caused an epidemic of encephalitis in several coastal counties of Sao Paulo in 1975: there were 462 cases, 61 of which were fatal. No virus was isolated from 420 sera from patients with encephalitis but 9 isolations were made from brain tissue. Isolated from 2 of 395 sentinel mice exposed in the epidemic area, and from a rufous collared sparrow, Zonotrichia capensis, collected in the same area. Epidemiology suggests mosquito vectors, Psorophora ferox and Aedes scapularis, and possibly a bird natural host. Hemagglutinin present in mouse brain tissue. Serologically related to other fla-viviruses but distinguishable from them. Pathogenic on injection into mice and hamsters. Replicates in Vero cells and BHK21 cells with CPE.

rodent parvoviruses Can be divided by their serological properties into four species with their respective strains as follows:

(1) Kilham rat virus H-3 virus X-14 virus LS virus

Hemorrhagic encephalopathy virus of rats (HER) Kirk virus

Rotavirus

Krisini 9 HV

(4) Mice minute virus MVMp

MVMi

H-1, HT and HB may be human viruses as they were apparently recovered from human tissues, but antibodies to them are rare in humans and they are pathogenic to newborn hamsters, a feature not yet observed with parvoviruses outside the rodent group.
