Use of ethnoveterinary medicinal plants in cattle by Setswana-speaking people in the Madikwe area of the North West Province of South Africa.
The study indicated that Setswana-speaking people in the North West Province have a rich heritage of ethnoveterinary knowledge, which includes all aspects of ethnovesterinary medicinal plant use. Expand
Copper toxicity in ruminants: air pollution as a possible cause.
Prophylactic licks, containing zinc sulphate and sulphur, seemed to be successful in protecting cattle against the effects of the copper in the contaminated grazing, and Buffalo and impala in an adjacent area of the Kruger National Park were found to have significantly higher liver copper levels than animals elsewhere in the Park.

Establishment and validation of primary hepatocytes of the African sharptooth catfish (Clarias gariepinus).
The primary catfish hepatocyte cell culture system, expressing CYP1A when exposed to B[a]P, could be used as a biomarker for aromatic hydrocarbon pollutants in aquatic ecosystems of southern and East Africa. Expand
The toxicity of Senecio inaequidens DC.
The toxicity of a plant implicated in an outbreak of poisoning of stock in Frankfort, Free State Province, South Africa was confirmed by confirming the presence of 4 different compounds, namely retrorsine and senecionine (known to be hepatotoxic) and 2 unidentified compounds. Expand
Provisional clinical chemistry parameters in the African sharptooth catfish (Clarias gariepinus).
The values obtained are a useful starting point for using C. gariepinus as a bioindicator species, and the very low plasma thyroxine (T4) levels have important implications for laboratory personnel, who will have to set up calibration and standardisation adaptations for the methods that are generally designed for human samples.

Two outbreaks of fluorosis in cattle and sheep.
Two outbreaks of fluorosis in cattle and sheep were investigated in the Northern Transvaal. The animals exhibited severe dental lesions, lameness and exostoses. Plasma fluoride concentrations wereExpand
Claviceps cyperi, a new cause of severe ergotism in dairy cattle consuming maize silage and teff hay contaminated with ergotised Cyperus esculentus (nut sedge) on the Highveld of South Africa.
This is the first report of bovine ergotism not associated with the Poaceae infected with Claviceps purpureum or endophytes but with the family Cyperaceae and this particular fungal phytopathogen. Expand
Datura contamination of hay as the suspected cause of an extensive outbreak of impaction colic in horses.
Comparative analyses of single specimens of dried seed of the 2 species collected from both fertilised and waste areas revealed that young South African Datura spp. Expand
Cardiomyopathy in ostriches (Struthio camelus) due to avocado (Persea americana var. guatemalensis) intoxication.
Nine out of 120 ostriches died from congestive heart failure within 96 h of ingesting avocado leaves and immature fruit in an avocado orchard containing Hass and Fuerte cultivars. Foliage andExpand
The assessment of biomarkers in sentinel cattle for monitoring vanadium exposure.
Significant correlations were found between the exposure dose (end-dose) just prior to slaughter and the concentrations of vanadium in the coccygeal vertebrae, liver, diaphragm and rib-bone in descending order of magnitude. Expand
