Introduction: A contribution to the regional epidemiological profile of the most common fungal agents in Public Health Services
in Cuiabá, state of Mato Grosso, including university hospitals and polyclinics. Methods: Clinical specimens (n = 1,496) from
1,078 patients were collected, submitted to direct mycological exam (potash or stick tapemethod) and cultured in specific mediums.
Dermatophytic and non-dermatophytic agents were identified according to micromorphology (Ridell technique). Results: The majority
of the 1,496 specimens were skin (n = 985) and nail exams (n = 472). Of the 800 positive cultures, 246 (30.8%) corresponded to
dermatophytes and 336 (42%) to yeasts of the genus Candida, 190 (23.7%) to other yeasts, 27(3.4%) to non-dermatophytic filamentous
fungi and one (0.1%) the agent of subcutaneous mycosis. Lesions considered primary occurred in greater numbers (59.5%) than
recurrent lesions (37.4%), with a greater concentration of positivity occurring on the arms and legs. Conclusions: Comorbidities,
allergies and diabetes mellitus were conditions associated with greater positivity in direct mycologicalexams and cultures. Positive
culture was considered a definitive diagnosis of fungal infection and confirmed 47.8% of diagnostic hypotheses.
KEYWORDS: Dermatomycoses; Fungal agents; Mato Grosso.
In dermatology out-patient clinics, principally in tropical countries,
cases of tineas (cutaneous/skin mycoses) and other superficial fungal
infections presenting highlycharacteristic clinical aspects are observed
daily, definitively favoring their diagnoses. Several factors affect the
higher incidence of superficial and cutaneous mycoses, including:
bioclimatic conditions favorable to the development of fungi in
saprophytic life; promiscuity; sweating; prolonged contact with pets
(cats and dogs), since they constitute potential reservoirs of certaindermatophytes; and contaminated water from swimming pools and
surrounding risk areas (paving close to pools)24.
Superficial and cutaneous mycoses can be detected on the skin, in
hair, on the nails, in periungual folds, in the mucosa and cutaneomucosal
zones. It is not possible to outline an exact profile of the epidemiology
of superficial and cutaneous mycoses, because they are not diseases thatrequire compulsory notification. Certain tineas are extremely contagious,
provoking microepidemics in schools or micro-epizootics, the latter
especially among captive animals (rabbits, guinea pigs, mice and rats),
though they also occur in rural areas and occasionally do not provoke
obvious clinical lesions42,44,45.
Epidemiological studies in Brazil have demonstrated the distribution
ofetiological agents responsible for superficial and cutaneous fungal
infections in several geographical regions. The literature contains data
collected and analyzed from the states of São Paulo9, Goiás12, Rio Grande
do Sul3, Santa Catarina47, Minas Gerais30, Distrito Federal8, Amazonas16,
Paraná40 and Ceará6.
However, our review found no record of any kind of study conducted
in the...
