Consecutive brain to brain passage series were conducted in suckling and weanling mice. Specific anti-Sindbis HR neutralization tests and protection tests demonstrate that these viruses are derived from the parent Sindbis HR., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-31-2-261
