Van Rensburg, S.W.J.; Du Toit, P.J.
(Pretoria : The Government Printer, 1947)
An investigation was undertaken with the object of ascertaining to what
extent quarters which have always been free from infection with known
pathogenic bacteria secrete abnormal milk, and to determine the role played
by ...

1. Considerable variation in susceptibility to potassium mono-fluoroacetate
has been found to exist among various species of laboratory animals.
2. The compound is not affected by actively fermenting ruminal flora
nor ...

Polson, A.; Du Toit, P.J.
(Pretoria : The Government Printer, 1947)
(1) A new method for the analytical determination of the diffusion constant
of a virus is described.
(2) This method is based upon the amount of virus which diffuses across
the interface formed between an infective ...

(Pretoria : The Government Printer, 1947)
The occurrence of seventeen mites has been recorded apparently for
the first time in South Africa. Cheyletiella parasitivorax has also been
included, having been recorded only from Onderstepoort. These mites are
apparently ...

From the findings reviewed in this paper it seems clear that the pathological
changes in bluetongue concern mainly:
(a) the vascular system,
(b) the skeletal musculature.

Alexander, R.A.; Du Toit, P.J.
(Pretoria : The Government Printer, 1947)
1. The technique used for the propagation of the Bekker strain of bluetongue
virus in the developing chick embryo is described in detail.
