Mycotoxicosis is commonly a food-spoilage disease, but can occur from indiscriminate ingestion of mushrooms.
- Fusarium spp - zearalenone toxicity (estrogenic metabolite)
- Aspergillus spp - aflatoxicosis
- Penicillium spp - tremorgenic mycotoxicosis
- Amanita spp (mushrooms) - mainly gastrointestinal disease and psychotropic effects
- Gyromitra esculenta - False morel mushroom - rare cause of fatal hemorrhagic diarrhea
Clinical signs vary depending on the mycotoxin, but signs are often neurological and gastrointestinal in effect. Some toxins such as aflatoxin result in sudden death due to internal hemmorhage and DIC]], whereas other may elicit only mild gastrointestinal effects when consumed in lower doses such as Fusarium and infertility effects.
Although they constitute a small portion of the clinical cases, mycotoxicoses often require special effort at both diagnosis and treatment, which can be challenging.
Establishing an accurate diagnosis is crucial to minimize exposure and provide adequate treatment.
In most cases, pathologic testing, and analytical chemistry analysis of suspect feed are necessary to reach a diagnosis.
Treatment usually requires aggressive intravenous fluid therapy, N-acetylcysteine and antioxidants such as ascorbic acid.
