Mycoses
|January 1, 1994
Summary
This study analyzed 2350 samples, finding dermatophytosis in 36.6% of cases. Trichophyton rubrum is the leading cause of superficial fungal infections in Mexico, particularly tinea unguium and tinea pedis.
Area of Science:
- Medical Mycology
- Dermatology
- Infectious Diseases
Background:
- Superficial mycoses are common skin infections.
- Understanding causative agents and prevalence is crucial for effective treatment.
- Trichophyton rubrum is a significant dermatophyte globally.
Purpose of the Study:
- To determine the prevalence of dermatophytosis.
- To identify the etiological agents of superficial mycoses.
- To track trends of Trichophyton rubrum in Mexico.
Main Methods:
- Analysis of 2350 biological samples from patients with superficial mycoses.
- Direct microscopic examination with 15% KOH.
- Culture on Sabouraud glucose agar with antibiotics.
Main Results:
- Dermatophytosis confirmed in 860 (36.6%) cases.
- Trichophyton rubrum accounted for 80.9% of confirmed dermatophytosis.
- Tinea unguium (60%) and tinea pedis (25.6%) were most frequent.
- Increasing prevalence of T. rubrum observed in Mexico.
Conclusions:
- Trichophyton rubrum is the predominant cause of superficial mycoses in the studied Mexican population.
- The rising incidence of T. rubrum warrants attention for public health strategies.
- Continued surveillance is necessary to monitor dermatophyte trends.
