There has been a recent increase in the frequency of skin mycoses, cou
pled with changes in the epidemiology and distribution of the species
responsible. Periodic epidemiological analyses of these diseases are t
hus required to ensure their efficacious control. Hair fragments, skin
scrapings, specimens from vesicles and blisters and nail parings were
seeded on Petri dishes loaded with Sabouraud or Mycosel agar, supplem
ented with chloramphenicol and with chloramphenicol plus cycloheximide
respectively. Parts of each specimen were also mounted in 10% potassi
um hydroxide for examination under the microscope. Yeasts prevailed ov
er dermatophytes. Microsporum canis was the most frequent dermatophyte
, followed by Trichophyton rubrum, IT: mentagrophytes and Epidermophyt
on floccosum. Tinea corporis was the most common mycosis, followed by
tinea unguis, tinea capitis and tinea pedis. Men were chiefly bearers
of tinea cruris and tinea pedis, women of tinea corporis, and children
and teenagers of tinea capitis. Some examples of the transmission of
infection through interhuman contact, via animals and from the soil ar
e also presented.
