Molecular analysis of dermatophytes (based on PCR fingerprinting) revealed high clonal differentiation between the genus and species. Microsporum canis (zoophilic dermatophyte, belonging to genus Microsporum), responsible for most cases of tinea capitis in children, tinea corporis in adults and dermatophytoses in cats, is very unique in comparison with other dermatophytes. Results of most molecular studies show that there is no clonal differentiation within M. canis as distinct from other species. The aim of this study was application of (GACA)4 repetitive primer and (ACA)5 primer for typing of M. canis strains isolated from human and animals in Central Poland. Fungal strains: 32 clinical isolates of M. canis, originated from patients from Central Poland; 11 strains isolated from infected cats (6) and dogs (7), reference strains of M. canis (CBS 113480), T rubrum (CBS 120358), T mentagrophytes (CBS 120357) and E. floccosum (CBS 970.95). The genomic DNAs of the strains were used as a template in RAPD reaction. No differentiation was observed for the analyzed M. canis strains using (GACA)4 and (ACA)5 typing.

Tinea capitis is a fungi infection of the scalp that disproportionately affects children in rural and underserved communities in Nigeria. A case-control study was conducted to identify the causative agents and factors that predispose school pupils to tinea capitis in two selected government-owned public primary schools in Osogbo, Southwestern Nigeria. A total of 230 participants were included in the study: 115 cases and 115 controls. Head scrapings were collected from pupils with suspected T. capitis lesions, viewed under Potassium Hydroxide smear microscopy and cultured in Sabouraud’s Dextrose Agar (SDA) for characteristic fungal elements. A total of 105 (91%) samples were successfully cultured, of which 56% (59/105) were from male pupils. Tricophyton rubrum (34%), Tricophyton mentagrophyte (31%) and Microsporum canis (18%) were the most prevalent organisms. Other dermatophytes obtained include Microsporum nanuum (3%), Epidermophyton floccusum (6%), Tricophyton verucosum (1%), and Microsporum gypseum (8%). Pupils between the ages of 4 and 7 years had the highest distribution (67%) followed by those between the ages of 8 and 11 years (39%). Playing with animals, the sharing of combs and not bathing with soap were significantly associated with tinea capitis infection (P < 0.05) in each case. This study showed a high prevalence of tinea capitis caused by the identified dermatophytes in the area.

FUNDAMENTOS: Tinea capitis é importante infecção fúngica de interesse dermatológico e pediátrico. No Brasil sua prevalência é desconhecida, e os agentes causais principais são o Trichophyton tonsurans nas regiões Norte-Nordeste e o Microsporum canis no Sul-Sudeste do país. Conhecimento sobre gênero e espécies mais prevalentes tem importância sanitária e terapêutica. OBJETIVOS: Identificar espécies de dermatófitos, causa de Tinea capitis, em serviço universitário que atende clientela do Sistema Único de Saúde, de procedência urbana e rural, no interior do Estado de São Paulo. MÉTODOS: Amostras de casos clínicos suspeitos de Tinea capitis, procedentes da área de abrangência da Faculdade de Medicina de Botucatu-Unesp, foram investigadas por exame direto e cultivo visando ao diagnóstico e isolamento do agente causal. RESULTADOS: De 1.055 suspeitas, 594 foram confirmadas por exame direto, em 364 (61,1%) isolou-se o agente: M. canis em 88,2%, seguindo-se T. tonsurans (4,7%), T. rubrum (3,3%), M. gypseum (1,9%), T. mentagrophytes (1,6%). O sexo masculino correspondeu a 55,7% dos casos, e a faixa etária entre 0-5 anos predominou com 62,6% (p < 0,05). CONCLUSÕES: A prevalência detectada do M. canis superou o esperado para a Região Sudeste do Brasil. A freqüência de 88,2% pode estar influenciada por pacientes procedentes da zona rural. Esse dado deve ser considerado quando de decisão terapêutica.

ZusammenfassungHaar- und Kopfhauterkrankungen können auch bei Kindern und Jugendlichen auftreten. Einen verstärkten täglichen Haarverlust nennt man Effluvium, eine objektiv sichtbare Haarlichtung Alopezie. Ein Haarwachstumszyklus besteht im Wesentlichen aus dem Anagen (Wachstumsphase, 3–6 Jahre) und dem Telogen (Ruhephase, 2–4 Monate). Anamnestisch ist bei Haarausfall entsprechend der Dauer der Telogenphase vor allem nach Ereignissen vor 2–4 Monaten zu fragen (hohes Fieber, Heparinspritzen), da die meisten das Haarwachstum belastenden Ereignisse zum Abbruch der Anagenphase führen. Diagnostische Methoden sind der klinische Epilationszugtest, die Trichoskopie, das Trichogramm und gezielte Blutanalysen (Eisenmangel). Zu den harmlosen Haarwachstumsstörungenzählen das „kurze Anagen“ oder das „lose Anagenhaar“. Mit 1–2 % Lebenszeitinzidenz ist die Alopecia areata auch bei Kindern relativ häufig und meist selbstlimitiert. Differenzialdiagnostisch abzugrenzen sind die Aplasia cutis congenita, die Trichotillomanie und eine Microsporum-canis-Infektion. Am wichtigsten ist die rechtzeitige Diagnosestellung bei der Tinea capitis. Sie muss in der Regel systemisch behandelt werden, um eine permanente, narbige Alopezie zu verhindern. Schließlich gibt es einige charakteristische Wuchsstörungen des Haarschaftes wie z. B. die Monilethrix, Trichorrhexis nodosa, Trichorrhexis invaginata und die Trichothiodystrophie. Sie alle führen zu erhöhter Brüchigkeit der Haare. Harmlos und nicht erhöht brüchig sind Schaftstörungen wie Pili anulati oder das Phänomen der „unfrisierbaren Haare“.
