|April 1, 1977
Summary
Bacillus subtilis (B. subtilis) and its metabolites were tested for pathogenicity in mice and rats. Studies found no adverse health effects or organ damage, indicating B. subtilis is non-pathogenic to these animals.
Area of Science:
- Microbiology
- Toxicology
- Animal models
Context:
- Assessing the safety of Bacillus subtilis is crucial for its potential applications.
- Understanding the pathogenicity of microbial strains is essential in food safety and biotechnology.
Purpose:
- To evaluate the potential pathogenicity of Bacillus subtilis (B. subtilis) and its metabolites in mammalian models.
- To determine the safety of B. subtilis for use in various applications through bioassays.
Summary:
- Bioassays were conducted on white mice and rats using various strains of B. subtilis, including cultures, cellular suspensions, and metabolic products.
- Both peroral and intraperitoneal administration routes were employed, with no observed changes in animal behavior or health.
- Histopathological examination revealed no macroscopic changes in organs, and B. subtilis was only found in the digestive tracts of perorally infected animals.
Impact:
- Provides evidence for the non-pathogenic nature of B. subtilis in mice and rats.
- Supports the safe use of B. subtilis in food, feed, or probiotic applications.
- Contributes to the risk assessment of B. subtilis in biological and industrial settings.
