A new model of experimental Bacteroides fragilis infection in mice and rats
Chemotherapy
|January 1, 1982
Abstract:
We describe a method, based on Selye's granuloma pouch, for establishing reproducible Bacteroides fragilis infections in both mice and rats starting from rather low inocula. The infected pouches resemble abscesses and phlegmons. This model is promising for studies of antibiotic therapy in that both bacterial kinetics and antibiotic levels can be followed in the exudates.
Insights
Researchers developed a reproducible method to infect rodents with Bacteroides fragilis, creating abscess-like models. This technique is valuable for studying antibiotic treatments by tracking bacterial growth and drug levels in infected tissues.
Area of Science:
- Microbiology
- Infectious Diseases
- Animal Models
Background:
- Bacteroides fragilis is an opportunistic pathogen.
- Abscess and phlegmon formation are common bacterial infections.
- Reproducible animal models are crucial for studying infection and treatment.
Purpose of the Study:
- To establish a reproducible animal model for Bacteroides fragilis infection.
- To create an infection model that mimics abscesses and phlegmons.
- To facilitate studies on antibiotic therapy efficacy.
Main Methods:
- Utilized Selye's granuloma pouch technique.
- Inoculated mice and rats with low doses of Bacteroides fragilis.
- Monitored infection development and exudate characteristics.
Main Results:
- Successfully established reproducible Bacteroides fragilis infections in mice and rats.
- The infected pouches exhibited characteristics of abscesses and phlegmons.
- The model allows for tracking of bacterial kinetics and antibiotic levels in exudates.
Conclusions:
- The described method provides a reliable animal model for studying Bacteroides fragilis infections.
- This model is suitable for evaluating antibiotic therapies.
- The model enables in-situ monitoring of bacterial and antibiotic dynamics.
