Abstract |
To determine fungal species distribution of interdigital intertrigo among seafarers in Dakar, Senegal, a cross-sectional study was carried out from May to August 2017 among seafarers clinically diagnosed with interdigital intertrigo. A questionnaire was filled to each patient before sampling the affected folds and transporting to Aristide Le Dantec University Hospital where mycological analyses were realized. Species identification by MALDI-TOF MS was performed in Marseille, France. In total, 169 men (21–66 years) were included. Few of them (3%) had a high level of education and the duration of the mycosis exceed 10 years for 88% of patients. Direct microscopic examination (ME) was positive in 34.3%. Among samples with positive ME, 58.6% had positive culture. An overall incidence of 30.2% was found. Patients with confirmed cases aged between 28 and 66 years. Among them, those between 36–50 years were predominant (52.9%). Those with a high level of education were less representative (2%). For 52.1% of patients, the duration of the mycosis was superior to 10 years. Furthermore, 57% of cases were significantly associated with other types of tinea pedis and/or onychomycosis (P=0.03). Culture was positive in 23.7% isolating 43 strains successfully identified at the species level by MALDI-TOF MS for 31 isolates: 20 Candida and 11 dermatophytes. The rest was identified only at the genus level belonged to Fusarium. In definitive, MALDI-TOF MS could be a useful tool for routine and fast identification of dermatophytes, yeasts and NDFF in clinical mycology laboratories.
