Many of the methods used in participatory research are drawn from mainstream disciplines and conventional research itself involves varying degrees of participation. The key difference between participatory and conventional methodologies lies in the location of power in the research process.
Symptoms of botulism usually start around 7-10 days after contamination. The botulinum toxins block the action of the nerves on the muscles. As a result, the first signs of botulism are muscle weakness and poor co-ordination. In the early stages the horse has muscle tremors.
Food poisoning. In botulism food poisoning, the toxin is produced by the vegetative cells of C botulinum in contaminated food, and preformed toxin then is ingested with the contaminated food. The incubation time can vary from a few hours to 10 days, but most commonly is 18â36 hours.linical Manifestations. Botulism is a disease caused by the toxin of a diverse group of clostridia called C botulinum. This neurotoxin characteristically causes a symmetrical, descending paralysis (Fig. 18-3). The symptoms of botulism can occur in both the nervous system and the alimentary tract of the patient.
