Este estudo avaliou o potencial de cães e gatos em disseminar fungos dermatófitos, o perfil epidemiológico mais suscetível e as principais síndromes clínicas associados à dermatofitose humana. Foram coletados e cultivados pêlos e escamas de 21 gatos e 33 cães domiciliados com 25 proprietários com diagnóstico de dermatofitose. Tanto crianças como adultos adquiriram a dermatofitose a partir do contato com cães e gatos. A maioria das crianças apresentava Tinea capitis enquanto os adultos apresentavam Tinea corporis. Dos animais avaliados, 67% (36/54) foram positivos para fungos dermatófitos, sendo 95% (20/21) dos gatos e 49% (16/33) dos cães positivos. Dos gatos analisados, tanto assintomáticos como sintomáticos podem ter transmitido a doença. Quanto aos cães, os assintomáticos foram provavelmente os principais veiculadores da dermatofitose aos seus proprietários. Das amostras positivas em gatos, e em 94,4% das positivas em cães, o dermatófito isolado foi o Microsporum canis.

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 more common in children than in adults. Due to the low incidence of this condition among adults, it is frequently misdiagnosed as other scalp diseases, such as seborrheic dermatitis, psoriasis, and cellulitis. Herein, we describe an 82-year-old woman who presented with erythematous scaly patches and alopecia. Mycological examinations revealed tinea capitis caused by Microsporum canis. The patient was then successfully treated with antifungal medications.

Introducción: La dermatofitosis son micosis cutáneas causadas por distintos hongos queratinofílicos con capacidad de invadir la capa cornea de la piel, pelo y uñas. Microsporum canis es un dermatofito geofílico que afecta niños y adolescentes causando tinea cápitis y tinea corporis, principalmente. Para esta infección están disponibles diferentes tratamientos de uso tópico o sistémico, sin embargo, su efectividad es mínima dada su baja permeación, además, toxicidad y diferentes efectos adversos principalmente con los medicamentos sistémicos son descritos. De acuerdo con lo anterior, la búsqueda de nuevas moléculas activas, es necesaria. Objetivo: Evaluar la actividad antifúngica y citotóxica de derivados semisintéticos del eugenol frente a Microsporum canis y células de mamífero. Materiales y métodos: El efecto antifúngico y citotóxico del aceite esencial (AE) de Syzygium aromaticum (aceite de clavo), eugenol y dos derivados semisintéticos del eugenol (metiliso-eugenol e iso-eugenol) fue evaluado mediante la prueba de sustrato impregnado determinando la inhibición del crecimiento micelial de M. canis y la toxicidad en células Vero por el método colorimétrico usando la sal de tetrazolio MTT. Los resultados fueron expresados como porcentajes de inhibición y concentración citotóxica 50 (CC50), respectivamente. Resultados: La inhibición del crecimiento micelial de M. canis luego del tratamiento con el AE y todos los compuestos en estudio, mostró ser de un 100% cuando fueron probadas concentraciones de 300mg/mL. Adicionalmente, nuestros derivados mostraron ser parcialmente tóxicos para las células de mamífero con CI50 entre 60-100 g/mL. Conclusiones: Estudios complementarios para la determinación de la inhibición de la germinación y concentración fungicida, así como otros estudios de toxicidad, son pertinentes.

Common Clinical Finding

The aim of this study was to isolate and identify dermatomycosis causing dermatophysis in EL- Beida, Libya. In this study  253 cases of skin infection were collected from the dermatology unit at  EL- Thoura hospital in EL- Beida, Libya. These cases clinically diagnosed as superficial mycosis ,130 ( 51.4%) were isolated from males and  123 ( 48.6% )  were females. These cases were classified into 5 groups according to age (1-10, 11-20, 21-31, 31-40 and above 40 year). Our results showed that young ages were more liable to infection than adult. The cases  involved in this investigation represented different occupations. The highest incidence was recorded between school children 40.3 %, followed by workers, farmers and others  29.2%, house wives  17.8%  while it was 12.6% among children less than 5 years. Concerning the clinical and mycological finding, it was noticed that 74 (63.8%) cases gave positive culture while the remaining cases were negative. Scalp infection was the most common clinical finding, in this study Tinea capitis was the most frequent  42.8%  cases,  Microsporum canis and Trich ophyton violaceum were the most common fungi isolated. Tinea corporis and Tinea cruris were diagnosed clinically in 68 (26.8%) cases,  24.4% were from  Tinea corporis while the fungus isolated were   Microsporum canis 41% , Epidermophyton floccosum  14% and Tinea cruris with incidence of  0.8% in which Trichophyton  tonsurans was the only fungus isolated . Onychomycosis and Tinea pedis were seen in  3.4% and the most important isolated agents were  Epidermophyton floccosum 50%, followed by  Microsporum canis and Trichophyton rubrum  25% for each.  This study demonstrates that the prevalence of dermatophytoses in EL- Beida cit, was high (47%), and was more common in males than females. The present study has also indicated that tinea capitis was the dominant (43%).
