| Summary | Experimental rabbits provide evidence for translational research regarding the pathogenies or treatment of human diseases. We developed a novel method for regenerating the middle ear mucosa using autologous cultured nasal mucosal epithelial cell sheets, and evaluated the wound healing process in the middle ear mucosa of experimental rabbits. Nonetheless, vigilant microbiological monitoring of experimental animals is essential to effectively prevent a decline in their health conditions, which may affect the research results. We experimented with contamination of Pasteurella multocida in non-specific-pathogen-free (SPF) rabbits (without microbiological monitoring). Most non-SPF rabbits had otitis media, whereas SPF rabbits did not, which affected their results during the mucosal regeneration study. The contamination was resolved by changing the experimental design from using non-SPF rabbits to that using SPF rabbits. It is crucial to use the SPF animals for any surgical intervention studies. |
