(Published by the Government Printer, Pretoria., 1986)A sensitive and reliable enzyme-linked immunosorbent assay for the detection of antibodies to Cowdria ruminantium in serum and C. ruminantium antigen in Amblyomma hebraeum nymphae is described. For the screening of antibodies, ...
-
(Published by the Government Printer, Pretoria., 1986)An enzyme-linked immunosorbent assay was used to detect Cowdria ruminantium antibodies during the course of heartwater disease. IgM antibodies reached a maximum on the 4th day after infection and disappeared on the 7th ...

(Published by the Government Printer, Pretoria., 1986)Ten pregnant buffalo cows, six of which were subsequently shown to be carriers of SAT 1, 2 and 3 viruses, were captured in the Kruger National Park (KNP) and allowed to calve in captivity. The buffalo cows and calves were ...
-
(Published by the Government Printer, Pretoria., 1986)Three groups of young buffalo in captivity were infected by exposing them to similar buffalo in the acute stages of infection induced by needle inoculation with SAT 1 or 2 viruses. Clear foot lesions developed in most of ...
-
(Published by the Government Printer, Pretoria., 1986)A structure, presumably a sensory receptor in the nippled tubercles of Schistosoma mattheei, previously observed by scanning electron microscopy, was studied further by light and transmission electron miccroscopy. The ...
-
(Published by the Government Printer, Pretoria., 1986)Notwithstanding morphological differences, the ultrastructure of Cowdria ruminantium cultured in vitro concurred to a large extent with that in previous in vivo studies. Two distinct forms of the organism, elementary and ...
