Subacute and chronic toxicosis: - Subacute poisoning is more common. Animals ingesting toxic amounts of Microcystis blooms often develop an acutely lethal syndrome characterized by gastrointestinal disturbances (vomiting depending on species, abdominal pain and often diarrhea which may be bloody), followed by weakness, pallor of the mucous membranes, severe reduction in both activity and responsiveness, and death. Fibrosis and cirrhosis may develop. Poisoning is common in the late summer or fall when other forage is scarce. No specific treatment for microcystin or nodularin toxicosis has been explored. Identify poisonous plants and their toxins in the western US. This information has also been used to help ranchers limit their losses. DNA will be saved from all screened animals.
Oleander (Nerium oleander) is an outdoor shrub, popular for its evergreen qualities and delicate flowers.
