Summary

A strain of rabbit-adapted “B” virus (Sabin and Wright, 1934) has been successfully transmitted intracerebrally to 1-day-old White Leghorn chicks. Virus from a chick-brain suspension of the 5th intracerebral passage was transmitted successfully to baby chicks by the following routes of exposure: intraperitoneal, intrarectal, intradermal, intracardial, intramuscular, intralingual, intranasal, and intracerebral. Baby chicks showed typical symptoms of “B” virus disease between 3 and 4 days after inoculation.
