    Abstract:
    UNLABELLED: Tinea capitis are common in Algeria and are a frequent reason for consultation. This mycosis affects children and rarely adults. This is a retrospective study over a period of 20 years from 1995 to 2015 at the mycology laboratory of the Pasteur institute of Algeria. OBJECTIVE OF THE STUDY: Observe the evolution of these tinea over the years, to study the epidemiological aspects and identify the responsible agents. PATIENTS: This study concerned patients of all ages and sexes living in the region of Algiers and the environs, consultant for various scalp lesions. MATERIALS AND METHODS: For each patient, a completed information sheet is developed in insisting on the presence of animals and people with similar lesions. For each sampling, direct examination and culture on Sabouraud medium and antibiotics are utilized. The cultures are put at T° 27 to 28°C and controlled regularly during 3 to 4 weeks. RESULTS: A total of 2664 samples were collected, 892 examinations were positive corresponding to a frequency of 33.48%. The age group 0-10 years is the most affected 710 cases (79.60%), with a slight predominance for male sex 502 cases (56.27%) and 390 cases (43.72%) for female sex. Eight hundred and fifty-five dermatophytes strains were isolated. Among the species found, Trichophyton violaceum is the most species isolated (59.41%), followed by Microsporum canis to 35.08%. In our series, the number of cases of tinea has increased slightly over the years, the rate of 26% in 2001 has progressed to 41.02% in 2015. From 1995 to 2011, T. violaceum was the predominant species, but from the year 2011 we see an increase of M. canis and decreased of T. violaceum. CONCLUSION: Tinea capitis remains frequent in Algeria and affects preferentially the children. T. violaceum and M. canis dominate the dermatophytic flora. Tinea trichophytic anthropophiles have progressively decreased in favor of tinea microsporic zoophiles who saw their number increased.
