dc.description.abstract | 1. Experiments conducted to demonstrate the susceptibility of horses and cattle are described. 2. The appearance of virucidal antibodies in the serum of these animals after infection is demonstrated by a technique of in vitro neutralization of virus. 3. The technique of tick feeding investigations is briefly described. 4. It is shown that- (a) larvae of R. appendiculatus will pick up infection for transmission as nymphae; (b) nymphae will pick up infection for transmission as adults; (c) the virus does not pass through the egg to the next generation; (d) infective nymphae tend to lose their infection after feeding on immune animals though some of the resulting adults may still be infective ; (e) the same occurrence was noted after feeding infective nymphae on susceptible animals but, particularly if sheep are the hosts, there is a danger of the nymphae reacquiring infection before detachment; (f) clean ticks do not acquire infection when feeding on an immune animal simultaneously with infective ticks. 5. The significance of the work is discussed. | en_ZA |
