A bluetongue-like virus was isolated from Japanese cattle with an infectious disease involving vesication and necrosis of the mucous membrane of the oral cavity and swallowing difficulties. The virus was successfully passaged by intracerebral inoculation in unweaned and weanling mice, 100%...

Between October and December, 1961, the author investigated 5 outbreaks of rinderpest in Egypt, introduced the LA vaccine, and established the c.f. techniques as routine laboratory methods. Sera and lymph nodes were collected and the results of c.f. tests recorded. Unvac-cinated calves were the...

The lapinized-avianized strain of rinderpest virus was successfully propagated in chick embryo tissue culture. A simple suspension method similar to that described by Maitland gave satisfactory results. Various culture conditions were studied for the establishment of a standard culture method. As a ...

After working on rinderpest during a stay of about 4 months in Nigeria, N. made several recommendations. Avianized strains of rinderpest virus should be studied, because of their possibilities in vaccination and because they are cheap to maintain. The c.f. test should be the routine lab. method of...

A strain of rinderpest virus was adapted to rabbits and attenuated for cattle. It did not regain virulence even after 10 successive passages through cattle. A method of simultaneous vaccination in which susceptible cattle were given the rabbit strain of virus plus hyper-immune serum was tested on...

These investigations were made to study problems involved in the production of complement-fixing antibody of rinderpest. In the first experiment 33 calves were used; 17 received virulent blood 14-16 days after a dose of toluolized vaccine. Only two had any reaction and these recovered after showing ...
