Summary
Candida albicans exhibits varying pathogenicity in oral models. Some strains cause tongue lesions, while others only penetrate the epithelium without visible effects in rats.
Area of Science:
- Microbiology
- Oral Biology
- Pathogenesis
Background:
- Candida albicans is a common opportunistic fungal pathogen.
- Understanding its behavior in the oral cavity is crucial for treating infections.
Purpose of the Study:
- To investigate the pathogenic potential of different Candida albicans isolates in an animal model of oral candidiasis.
- To determine the spectrum of mucosal pathogenicity of C. albicans on the dorsal rat tongue.
Main Methods:
- Sixteen Candida albicans isolates from clinical settings were used.
- Isolates were inoculated weekly into the mouths of Sprague-Dawley rats over 16 weeks.
- Oral swabs monitored yeast presence; tongues were examined grossly and histologically.
Main Results:
- Six isolates induced dorsal tongue lesions with varying severity.
- Ten isolates showed hyphal penetration of the tongue epithelium without eliciting lesions.
- Significant variation in pathogenicity was observed among the C. albicans isolates.
Conclusions:
- Candida albicans displays a spectrum of pathogenicity on the dorsal rat tongue.
- The ability to cause lesions differs significantly between isolates.
- Further research into the mechanisms of C. albicans oral pathogenicity is warranted.
