Microsporum audouinii: Emergence of an Etiological Agent of Tinea Capitis in Rio de Janeiro, Brazil (2012-2019)

The etiology of tinea capitis changes over time, mainly due to trend in migration. We report 19 cases of tinea capitis caused by Microsporum audouinii, an uncommon agent in South America, all of them confirmed by molecular methods. All patients were male. The average age was 6.1 years. 15 patients w...

Description
Summary:The etiology of tinea capitis changes over time, mainly due to trend in migration. We report 19 cases of tinea capitis caused by Microsporum audouinii, an uncommon agent in South America, all of them confirmed by molecular methods. All patients were male. The average age was 6.1 years. 15 patients were residents of Rio de Janeiro city and 4 were from neighboring cities. Among the patients submitted to follow-up, griseofulvin was prescribed for 8 of them. Due to medication shortages, terbinafine was prescribed for 5 patients, needing to be switched in 3 cases, with a bigger total average time until clinical improvement. The study reaffirms the emergence of a new etiological agent in Rio de Janeiro, Brazil.
