Hypothesis

Can rabbits serve as a relevant model for studying pneumonic tularemia in humans?

Conclusion

The study found that pneumonic tularemia in rabbits closely mimics the human disease, making rabbits a suitable model for research.

Supporting Evidence

  • Rabbits developed fever and weight loss after exposure to the bacteria.
  • No rabbits survived exposure at any dose.
  • Blood tests showed significant changes consistent with infection.
  • Radiographs indicated pneumonia and gastrointestinal abnormalities.

Takeaway

The researchers studied how rabbits get sick from a bacteria that can also make humans sick, and they found that rabbits show similar symptoms.

Methodology

Twenty young female NZW rabbits were exposed to aerosols of F. tularensis and monitored for clinical signs, temperature, weight loss, and hematological changes.

Potential Biases

Potential bias in the selection of rabbits and the controlled environment of the study.

Limitations

The study was limited to a small sample size and focused only on one strain of F. tularensis.

Participant Demographics

Young female New Zealand White rabbits.
