Efficacy of antifungal agents in the cornea. I. A comparative study
Abstract:
A standardized model of Candida albicans keratitis was developed in pigmented rabbits using a quantitative mycologic technique to evaluate the disease at intervals throughout the course. In this model, using two different infecting strains, the efficacy of five antifungal agents was compared. Amphotericin B, in concentrations of 0.5% to 0.075%, was superior to all other agents tested. Natamycin 5% ranked next, followed by 1% flucytosine, and 1% miconazole. Ketoconazole 1% was ineffective.
Insights
This study developed a rabbit model for Candida albicans keratitis. Amphotericin B demonstrated superior efficacy compared to other antifungal agents in treating experimental fungal eye infections.
Area of Science:
- Ophthalmology
- Mycology
- Infectious Diseases
Background:
- Candida albicans keratitis is a serious ocular infection.
- Standardized animal models are crucial for evaluating antifungal efficacy.
- Pigmented rabbit models offer advantages for studying ocular infections.
Purpose of the Study:
- To establish a standardized rabbit model for Candida albicans keratitis.
- To compare the in vivo efficacy of five antifungal agents against C. albicans keratitis.
- To identify the most effective treatment for experimental fungal eye infections.
Main Methods:
- Developed a standardized model of Candida albicans keratitis in pigmented rabbits.
- Utilized quantitative mycologic techniques for disease evaluation.
- Compared the efficacy of Amphotericin B, Natamycin, Flucytosine, Miconazole, and Ketoconazole.
Main Results:
- Amphotericin B (0.5%–0.075%) was the most effective antifungal agent.
- Natamycin 5% showed significant efficacy, followed by Flucytosine 1% and Miconazole 1%.
- Ketoconazole 1% was found to be ineffective in this model.
Conclusions:
- The developed rabbit model is suitable for evaluating antifungal agents.
- Amphotericin B is a highly effective treatment for experimental Candida albicans keratitis.
- This research provides valuable data for clinical treatment strategies against fungal eye infections.
