The disease ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Chronic African trypanosomiasis is associated with progressive behavioural deficits, for which there is a complex underlying central nervous system (CNS) pathology. This has been extensively studied in man and a range ...

Hence, the ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Cloacas of male ostrich chicks that had suffered prolapse of the phallus and cloaca were compared with cloacas of normal ostrich chicks of both sexes from the same area. Heavy infection of the cloacal and bursal tissue ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)High levels of seropositivity, in all probability attributable to Ehrlichia, were recorded in the serum of domestic ruminants throughout districts in South Africa where Amblyomma hebraeum, the vector of the heartwater ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Geeldikkop was induced in a sheep by dosing it orally with a crude extract of the steroidal saponins from Tribulus terrestris. GC-MS analysis of the sheep's ruminal contents, bile, faeces and urine for free and conjugated ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)The use of optical-density (OD) readings after a 6-h incubation period, as a suitable method to quantify the bacterial contamination on hatching eggs, was established by the use of pure cultures of five bacterial isolates ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Linear measurements and derived indices from striated trypanosomes in nine species of sub-Saharan birds representing seven families of the Passeriformes, were compared. The dimensions of the striated trypomastigotes from ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Two immunoperoxidase techniques, viz. avidin-biotin complex (ABC) and peroxidase-anti-peroxidase (PAP) procedures, were applied to paraffin-wax-embedded brain-tissue sections, from brains which had been fixed in 10% ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)The distribution of neutral mucins, sialomucins and sulphomucins was determined histochemically in the duodenum, jejunum, ileum and colon of the African elephant (Loxodonta africana). The techniques used were periodic ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Two outbreaks of neurotoxicoses are reported in cattle browsing on the leaves of Ficus spp. In the first outbreak, three animals died and one became ill. A sheep developed severe nervous signs, including tetanic spasms, ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Approximately 71 of the estimated 145 kilobase pairs of the genome of the South African isolate of lumpy-skin-disease virus, Neethling strain, was cloned into the plasmid vector pBluescribe. Selected clones were used in ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Previously published results of dosing trials, involving 82 ewes, revealed that 66% of the offspring of dams exposed to cultures of Diplodia maydis in the second trimester of pregnancy and 87% of lambs of ewes exposed ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)The three-dimensional structure and size of ostrich sperm is unknown. In this study, the morphology and dimensions of ostrich sperm were determined by scanning electron microscopy of semen samples obtained from sexually ...
-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Geeldikkop was induced in a sheep by oral administration of crude saponins from Tribulus terrestris. Centrifugation of the bile from this sheep gave a pale green sediment of crystalloid material which was insoluble in ...

-
(Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1994)Tibiotarsal rotation in ostrich chicks is a serious problem that accounts for considerable financial loss to ostrich farmers. Serum- and bone-mineral analyses of 20 ostrich chicks with tibiotarsal rotation were compared ...
