Hypothesis

This Brucella species might also have a reservoir in soil.

Conclusion

B. microti could still be isolated from the same soil samples 6 months after storage at 4°C, indicating long-term survival in soil.

Supporting Evidence

  • Five out of 15 soil samples tested positive for B. microti.
  • Three positive samples were from surface soil near mouse burrows.
  • Two positive samples were from an unaffected area.
  • Isolates showed 100% identity with known B. microti sequences.
  • Multilocus sequence analysis confirmed the identity of the strains.

Takeaway

Scientists found a type of bacteria called B. microti in soil, showing it can live there for a long time.

Methodology

Soil samples were collected and tested using PCR to detect B. microti, followed by direct cultivation on Brucella agar.
