Detection of Phototoxic Activity in Plant Specimens Associated with Primary Photosensitization in Livestock using a Simple Microbiological Test

Abstract

Ingestion of mushrooms is infrequently observed by owners and may be omitted from the initial history. When mushroom poisoning is suspected on the basis of histopathological lesions, additional history and tests may help to establish the diagnosis. Collection and identification of mushrooms from the animal’s environment will establish the types of mushrooms that the dog was potentially exposed to. Examination of vomitus, gastrointestinal contents, and/or feces for mushroom spores may provide definitive evidence of mushroom ingestion and possible identification of the genus and species. In human patients, early diagnosis is occasionally achieved by detection of amanitins in urine or other body fluids.” Due to delayed onset of clinical signs, patients usually receive only supportive and palliative treatment. The treatment for Amanita mushroom poisoning has recently been reviewed.” Unless treatment is initiated promptly after exposure and before significant amounts of toxin are absorbed, the final outcome of the case is dependent on the amount and type of mushroom ingested.
