THE YIELD OF RABIES VIRUS IN THE CHICK EMBRYO

1 From the Department of Animal and Plant Pathology of The Rockefeller Institute for Medical Research, Princeton, New Jersey
Rabies virus was inoculated intracerebrally in 8 day old chick embryos and the virus activity of pools of embryos titered after incubation at 3536°C. for different lengths of time. The virus reached a titer of 105.5 to 106.5 in 5 to to 6 days and remained at a rather constant level until the 9th day of the infection. The report by Kligler and Bernkopf that rabies virus will invade the very young embryo after inoculation on the chorioallantoic membrane was confirmed.
