Summary

Dermatophytes, fungi causing skin infections, were found in 4.9% of healthy individuals in Chile. Microsporum canis and Trichophyton mentagrophytes were identified, highlighting the need for infection prevention measures.

Area of Science:

  • Mycology
  • Dermatology
  • Public Health

Background:

  • Dermatophytes are fungi that cause superficial mycoses.
  • Understanding their prevalence in healthy populations is crucial for public health strategies.

Purpose of the Study:

  • To investigate the prevalence of dermatophytes in healthy individuals residing in Valdivia, Chile.
  • To identify specific dermatophyte species and their distribution across different body sites.

Main Methods:

  • Collection of 1060 skin samples from scalp, face, inguinal region, and sole of 265 healthy individuals.
  • Utilized the carpet technique for dermatophyte isolation.
  • Identification of isolated dermatophytes following Rebell and Taplin's methodology.

Main Results:

  • Zoophilic dermatophytes were detected in 4.9% of the healthy participants.
  • Microsporum canis was identified in 1.5% of children (scalp and inguinal area).
  • Trichophyton mentagrophytes was isolated from 3.4% of adults (feet and inguinal skin).

Conclusions:

  • Dermatophyte carriage exists in healthy individuals in Valdivia, Chile.
  • Specific species like Microsporum canis and Trichophyton mentagrophytes were prevalent in certain age groups and body sites.
  • Recommendations are provided to prevent mycosis and reduce infection risks.
