Toxigenic thermophilic and thermotolerant fungi
Applied Microbiology
|April 1, 1975
Abstract:
Twenty-three isolates of fungi, representing 13 thermophilic and thermotolerant species, were bioassayed for toxigenicity to brine shrimp, chicken embryos, and rats. Thirteen isolates representing nine genera were highly toxic to at least two of the three systems. Seven additional isolates of five genera were slightly toxic.
Insights
Fungal isolates were tested for toxicity using brine shrimp, chicken embryos, and rats. Many thermophilic fungi showed significant toxicity, indicating potential health risks.
Area of Science:
- Mycology
- Toxicology
- Microbiology
Background:
- Thermophilic and thermotolerant fungi are prevalent in various environments.
- Fungal toxins (mycotoxins) pose risks to animal and human health.
- Assessing the toxigenicity of fungal isolates is crucial for risk management.
Purpose of the Study:
- To evaluate the toxigenic potential of thermophilic and thermotolerant fungi.
- To identify fungal species that produce toxins harmful to biological systems.
- To determine the range of toxicity across different bioassay systems.
Main Methods:
- Twenty-three fungal isolates from 13 species were cultured.
- Bioassays were conducted using brine shrimp (Artemia salina), chicken embryos, and rats.
- Toxicity levels were categorized as highly toxic or slightly toxic.
Main Results:
- Thirteen fungal isolates from nine genera exhibited high toxicity to at least two bioassay systems.
- Seven additional isolates from five genera demonstrated slight toxicity.
- The results indicate a significant toxigenic capacity among the tested thermophilic fungi.
Conclusions:
- Certain thermophilic and thermotolerant fungi possess potent toxins.
- These fungi represent a potential hazard in various settings.
- Further research into the specific mycotoxins produced is warranted.
