Fusarium venenatum is a type A Trichocothecene producing fungus. Be careful of

what you eat. The manufacturer should probably be held liable for using a known

Type A producing fungus. The blurbs on this product claim a non-mycotoxin

producing strain is used. However, if the strain has has masked genes for

trichothecenes, the genes can be turned back on. Such a mechism has been

demonstrated for Aspergillus fumigatus and ergotamines. A. fumigatus has the

genes for proucing ergotamines. See the article below for F. venenatum. If

this does not open, go th entrez pubmed and type in Fusarium venenatum

mycotoxins and you will see what I mean. You can also do the same with A.

fumigatus ergotamines.

Dr Thrasher,  Thank you for responding.  What about the pet food with the

trichoderma longibrachiatum.

 

  

God Bless !!

I will look up Trichoderma. Do not feed the dog food with mold extracts in it

is my recommendation. I alway fed my dogs food scraps from the dinner table.

We also fixed them hamburger meat. Dogs are carnivores, not ominvores and

therefore should be principally fed meat. Also, never give them chocolate,

which can cause them severe liver injury.

Mayleen: Here is a partial answer to your question on Trichocerma

longibrachiatum (see below). If the organism is toxic to shell fish, what about

dogs and humans?

Toxicity assessment of peptaibols and contaminated sediments on Crassostrea

gigas embryos.

Peptaibols are known membrane-modifying peptides that were recently detected in

marine sediments and mussels collected from a shellfish farming area (Fier

d'Ars, Atlantic coast, France). In this investigation, embryotoxicity bioassays

with oysters (Crassostrea gigas) were performed to assess acute toxicity of

alamethicin and different groups of peptaibols produced by a Trichoderma

longibrachiatum strain isolated from marine environment. C. gigas embryos

appeared very sensitive to all the metabolites examined with higher toxic

effects for long-sequence peptides (EC50 ranging from 10 to 64 nM). D-shaped

larvae with mantle abnormality were particularly noticed when peptaibol

concentrations increased. Disturbances of embryogenesis were also observed

following exposure to organic and aqueous extract of sediments from Fier d'Ars

(EC50=42.4 and 6.6 g L(-1) dry weight, respectively). Although peptaibol

concentrations measured in these sediments could explain only a part of the

toxic effects observed, this study suggests that these mycotoxins can induce

larval abnormalities in a population of exposed animals at environmentally

realistic concentrations. Their detection in coastal areas devoted to bivalve

culture should be taken into account.
