The Four Key Strains of Bacillus clausii
Bacillus clausii is often used in multi-strain formulations like Enterogermina, where specific strains work together to provide therapeutic benefits. These strains are identified by codes related to their resistance to certain antibiotics, allowing them to be effective even when taken with antibiotics. Their antibiotic resistance is stable and not transferable.
O/C Strain: Chloramphenicol Resistance
Resistant to chloramphenicol, the O/C strain has antimicrobial properties through substances it secretes, such as a serine protease and clausin. It protects intestinal cells from toxins from pathogens like Clostridioides difficile and Bacillus cereus, contributing to gut balance and strengthening the intestinal barrier.
N/R Strain: Novobiocin and Rifampicin Resistance
The N/R strain is resistant to novobiocin and rifampicin. It modulates the immune system by balancing cytokine expression, which helps reduce inflammation and offers protection against infections and inflammatory conditions.
SIN Strain: Neomycin and Streptomycin Resistance
Resistant to neomycin and streptomycin, the SIN strain improves gut barrier function and immunity. It promotes the production of antimicrobial peptides like human beta defensin 2 and cathelicidin. This strain also produces riboflavin (vitamin B2), important for host cell function.
T Strain: Tetracycline Resistance
The T strain is resistant to tetracycline. It produces antimicrobial substances and has immunomodulatory effects, as well as producing high levels of riboflavin. Its resistance makes it useful during tetracycline therapy to help prevent antibiotic-associated side effects.
The Combined Power of Bacillus clausii Strains
The combination of O/C, N/R, SIN, and T strains in formulations like Enterogermina provides a broader range of benefits than single strains.
Benefits include:
- Enhanced Antimicrobial Activity: A wider range of antimicrobial peptides produced to fight various pathogens.
- Superior Antibiotic Compatibility: Can be taken with most antibiotics due to their specific resistance, helping prevent antibiotic-associated GI issues.
- Improved Gut Barrier Function: Strengthens the intestinal barrier, reducing permeability and preventing pathogen invasion.
- Powerful Immunomodulation: Regulates immune response and helps manage inflammatory conditions.
- Restoration of Microbiota Balance: More effective at restoring gut flora balance.
Comparison of Bacillus clausii Strains
| Characteristic | O/C Strain | N/R Strain | SIN Strain | T Strain |
|---|---|---|---|---|
| Antibiotic Resistance | Chloramphenicol | Novobiocin & Rifampicin | Neomycin & Streptomycin | Tetracycline |
| Antimicrobial Production | Serine protease, clausin | Antimicrobial substances | Antimicrobial peptides | Antimicrobial peptides, clausin |
| Immunomodulation | Protects from pathogen toxins | Balances cytokines | Stimulates antimicrobial peptides | Immunomodulatory activities |
| Vitamin Production | Riboflavin (lower levels) | Riboflavin (lower levels) | Riboflavin (high levels) | Riboflavin (high levels) |
| Key Protection | Against C. difficile and B. cereus toxins | Reduces inflammation | Strengthens gut barrier, boosts immunity | Mitigates antibiotic-associated GI distress |
Conclusion
The four Bacillus clausii strains—O/C, N/R, SIN, and T—demonstrate the value of a multi-strain probiotic approach. Each strain's unique antibiotic resistance and attributes, such as antimicrobial capabilities and immunomodulatory effects, contribute to the overall effectiveness. Together, they are effective in restoring gut flora, especially during antibiotic use. Their spore form ensures they reach and colonize the gut successfully, supporting digestive health and immunity.

Frequently Asked Questions
What does the O/C strain of Bacillus clausii do?
Answer: The O/C strain is known for its resistance to chloramphenicol and its ability to produce protective enzymes and peptides that fight against pathogenic bacteria, including the toxins from C. difficile and B. cereus.
Can Bacillus clausii be taken with antibiotics?
Answer: Yes, the specific strains of B. clausii (O/C, N/R, SIN, and T) are resistant to several common antibiotics and are often used to help prevent antibiotic-associated diarrhea when taken concurrently with antibiotic therapy.
What health conditions can Bacillus clausii help with?
Answer: Bacillus clausii is widely used to treat and prevent intestinal flora disorders, manage acute and persistent diarrhea in children and adults, and relieve symptoms of irritable bowel syndrome (IBS).
Are the different strains of Bacillus clausii all the same?
Answer: No, while they are all part of the same species, the O/C, N/R, SIN, and T strains have distinct, stable genetic differences, including their specific antibiotic resistance profiles and varying levels of enzyme or vitamin production.
How does Bacillus clausii help boost the immune system?
Answer: It acts as an immunomodulator, helping to balance the expression of cytokines and stimulating the production of antimicrobial peptides that enhance the body's natural defense mechanisms.
Is Bacillus clausii safe for children and infants?
Answer: Clinical trials have shown that B. clausii is safe for use in children and infants, with a generally excellent safety profile and tolerability, even at higher dosages.
How long does it take for Bacillus clausii to work?
Answer: The time to see an effect can vary depending on the condition being treated. For acute diarrhea, improvements are often seen within 1-3 days of starting treatment.
