Mycotoxicosis Flashcards
Indicate which feeds and conditions are more likely to encourage mould growth and mycotoxin production
fungi and bacteria produce mycotoxins during their most rapid growth stages and so rotten food, protein sources as well -mushrooms (fungi in the environment) plants under stress are prone to fungi attacks moister and heat encourage fungi growth
List some hepatoxin examples
Hepatotoxin examples; -Aflatoxicosis; dry dog food is a source if will effect DNA repair and there is a suppression of mitosis -Fumonisin B1; there is death of the cells causes Equine leukoencephalomalacia (has nervous signs) and Porcine pulmonary oedema syndrome
List 3 types of mycotoxicoses
3 types of mycotoxicoses -hepatoxin -neutrotoxin -pantulin
List some examples of neurotoxins
Neurotoxins examples -Ergotism caused by Ergot Alkaloids causes vasculitis and this leads to extremities falling off -Tremorgenic toxins; effect inhibiting Ca activated K ion channels in CNS or PNS lolitrem is produced by endophytic fungi which is apart of the rya grass
List some examples of neurotoxins
Neurotoxins examples -Ergotism caused by Ergot Alkaloids causes vasculitis and this leads to extremities falling off -Tremorgenic toxins; effect inhibiting Ca activated K ion channels in CNS or PNS lolitrem is produced by endophytic fungi which is apart of the rya grass is seasonal
Explain Trichothecenes
Trichothecens food contaminates causes diarrhoea and vomiting
How do you treat mycotoxicosis
Treatment; there really isn’t much you can do, you just treat the symptoms the success of the treatment depends on the amount of toxins
List ways to prevention of mycotoxicosis
Prevention of mycotoxicosis -crops are healthy -look for evidence of fungi in feed -mound control in building -bind the mycotoxicosis -dilute the food -watch out for kitchen waste
The feed of the dog for alfatoxin analysis
