Presence of dermatophytes in public spaces in the city of La Plata: A threat to society?

Abstract

Dermatophytes are the etiological agents of dermatophytosis, particularly affecting populations
with frequent exposure to animals, contaminated soil, or shared environments. Due to their high
transmissibility and zoonotic potential, they represent an important public health concern. The objective
of this study was to detect the presence of dermatophytes in public spaces commonly shared by humans
and animals, such as squares and parks in the city of La Plata, Argentina. A total of 72 soil samples were
collected. Fungal identification was performed based on macromorphological and micromorphological
characteristics, and the pH of each sample was also determined. Of the ten sampled public sites, seven
tested positives for dermatophytes. This finding confirmed the presence of organic matter and identified
the pH range favorable for fungal growth in several of the sampled areas. Individuals who choose to live
with companion animals must commit to ensuring animal health and welfare, as well as implementing
environmental hygiene and preventive practices. Identifying the species responsible for dermatophytosis
provides valuable insight into the risk factors associated with zoonotic superficial mycoses and supports
future epidemiological surveillance efforts.
