A new virus was isolated from cynomolgus monkeys for laboratory use imported from Indonesia in July, 1973.
The virus agglutinated erythrocytes of some avian and mammalian species and hemolyzed chick erythrocytes. The virus was eluted from the surface of chick red blood cells by its neuraminidase activity. The virus was inactivated by ether; its nucleic acid was RNA. On electron micrographs, the particles varied from 250 to 400 nm in diameter, being covered with envelopes in which the surface projections were embedded. The diameter of inner helical structure was about 18 nm.
These observations indicate that the virus belongs to a group of paramyxoviruses. On the basis of serological examinations, this virus can be identified as a new virus having some relations with Yucaipa or Bangore viruses. This virus is designated as“Murayama virus”from the name of the place where it was isolated.
