Abstract

Innocuity can be controlled in cultures of calf kidney cells after neutralization with formalin and elution of the virus. The neutralization of formalin by bisulphite does not adversely affect the virus, and the elution technique allows the recovery of minute quantities of virus added to a vaccine. ...

Abstract

The strength of the immunity in sheep vaccinated with inactivated trivalent vaccine can be measured either by the titration of neutralizing antibodies in cell culture or by the resistance to challenge inoculation. Virus titrations can be carried out in vaccinated sheep by multiple tongue...

Abstract

The method of determining whether a given strain (S2) is a variant of another strain (SJ is known as the "six point test", in which 6 groups of 4 cattle each, designated A, B, C, A1, B1, C1, are used. Groups A and A1, B and B1, and C and C1are inoculated with a vaccine consisting only of Sj, in...

Abstract

Immunity tests at present in use are discussed. A quantitative estimation is suggested. This is based on the formula K=T/V, when K is the protective index, T is the virus titre in controls and V is the virus titre in vaccinated animals. K is, therefore, a variable number of infective units which,...

An "index of protection" was calculated by dividing the virus titre of unvaccinated cattle by the titre of vaccinated cattle, following inoculation into the tongue of 104 LD50 of virus.-R.M.
