Purpose of Study

• To develop a model for studying chronic Pseudomonas aeruginosa infections.
• To investigate bacterial pathogenesis and host-pathogen interactions.
• To aid in the development of new therapies for chronic infections.

Methods Used

• Delayed inoculation of Pseudomonas aeruginosa 24 hours post-wounding.
• Use of full thickness excisional wounds in mice.
• Monitoring infection duration lasting seven to ten days.
• Involvement of medical students in procedural demonstrations.

Main Results

• Successful establishment of chronic infections without immune suppression.
• Infection model allows for detailed study of bacterial behavior.
• Demonstrated the feasibility of the protocol in immunocompetent mice.
• Potential for application in therapeutic development.

Conclusions

• This model provides a valuable tool for chronic infection research.
• It facilitates the study of host-pathogen interactions.
