Review
South Africa is blessed with one of the richest floras in the world, which--not surprisingly--includes many poisonous plants. Theiler in the founding years believed that plants could be involved in the aetiologies of many of the then unexplained conditions of stock, such as gousiekte and geeldikkop. His subsequent investigations of plant poisonings largely laid the foundation for the future Sections of Toxicology at the Institute and the Faculty of Veterinary Science (UP). The history of research into plant poisonings over the last 100 years is briefly outlined. Some examples of sustained research on important plant poisonings, such as cardiac glycoside poisoning and gousiekte, are given to illustrate our approach to the subject and the progress that has been made. The collation and transfer of information and the impact of plant poisonings on the livestock industry is discussed and possible avenues of future research are investigated.

Poisonous plants are a principal cause of economic loss to the US livestock industry. These losses are due to such things as deaths of livestock, abortions, photosensitization, debilitation and birth defects. Additionally, livestock producers and land managers are faced with such problems as fencing, loss of forage, altered grazing programs, and, in some instances, supplemental feeding programs and veterinary fees. Much can be done to prevent these losses if those involved know the poisonous plants growing on their ranges and the conditions under which the animal may be poisoned.

Analytical detection of Oenanthe crocata toxins in biological samples is challenging because of their instability, the lack of commercially available standards and the exceptionally low detection of these molecules using mass spectrometry. This work aims to report the used analytical methods that allowed identification of the main plant toxins in biological samples from an equid (an Arabian horse) fatality related to hemlock water dropwort (Oenanthe crocata Linnaeus) intake. Using both LC-DAD and LC-HRMS methods allowed identification (i) of oenanthotoxin in roots found on the site, root fragments found in the stomach, stomach content, kidney, and liver, and (ii) of the hydrogenated metabolite of oenanthotoxin (2,3-dihydro-oenanthotoxin) in roots found on the site, root fragments found in the stomach, stomach content, kidney, liver and spleen. Reported analytical data about Oenanthe crocata toxins can be useful for identification of the ingested plant and for supporting a poisoning diagnosis in such cases.

This paper reported 1 case of poisoning caused by stramonium. Cases of Datura poisoning have been reported nationwide, Its effect on the central nervous system of patients is characterized by first excitation and then inhibition, clinical manifestations include decreased gland secretion, dilated pupils, and tachycardia, etc. Its poisoning mechanism is anticholinergic effect, the effect on Peripheral nervous system is to inhibit Parasympathetic nervous system. Hemoperfusion combined with neostigmine anticholinergic therapy at the early stage of poisoning can effectively improve the clinical symptoms of patients in a short time.

The present report describes two novel cases of suspected intoxication with Galega officinalis in 6- and 21-year-old Arabian mares displaying acute respiratory signs. Both animals showed signs of pulmonary edema at physical examination, with the oldest of the two also manifesting severe dyspnea and foamy nasal discharge. The mares were grazing on the same meadow with hay available ad libitum. Botanical analysis of the latter showed traces of the toxic plant Galega officinalis (L.), which has been daily ingested at a dose of around 14 g of dry matter for three days. Based on the respiratory signs and the presence of goat's rue in the mares' feed, a presumptive diagnosis of plant poisoning was assumed. Dietary change and treatment allowed the 6-year-old mare to fully recover in 3 days while a longer period of about 2 weeks was necessary for the older horse. Horses avoid eating fresh goat's rue as its palatability is low, yet poisoning may still happen in these species when the plant is found in dried and processed feed material.

Pascalia glauca, a perennial herb known for its toxicity in ruminants, is one of the most important toxic plants in northwestern Argentina. This work describes several outbreaks of natural intoxication with P. glauca from different sources affecting cattle, sheep and goats in different production systems, with morbidity varying between 1% and 100%. Clinical signs included tremors in the hindquarters, recumbency and death. The liver showed swelling, congestion and a mottled appearance. Histopathologic findings included centrilobular hepatocellular necrosis with hemorrhage.
