ABSTRACT

Antecedentes. El gato, considerado el principal reservorio de Microsporum canis, cumple un rol importante en la aparición de las dermatomicosis cuando es habitante de zonas urbanas. Objetivos. Conocer y analizar la frecuencia de aislamiento de dermatofitos zoonóticos en una muestra de felinos del área urbana del Gran Mendoza. Métodos. Se seleccionaron animales de compañía y menores de un año que estuvieran transitoriamente en refugios y criaderos de zonas urbanas del Gran Mendoza. Se analizaron 45 muestras de gatos con y sin lesiones dermatológicas, recogidas mediante raspados de piel y depilación, o cepillado de Mackenzie, respectivamente. Las muestras se procesaron con KOH y glicerol tras exposición al calor. El cultivo se realizó durante 30 días en agar inclinado de Sabouraud glucosado y Lactrimel con cloranfenicol y cicloheximida. Resultados. La frecuencia de aislamiento de dermatofitos en este estudio preliminar fue de 13,3%. No se encontraron diferencias estadísticamente significativas en la procedencia, edad, sexo, raza ni estado dermatológico. Se hallaron dermatofitos zoonóticos en 2 animales de compañía de 21 que tenían contacto directo con niños o ancianos. M. canis tuvo una frecuencia de aislamiento de 83,3%. Conclusiones. La frecuencia de aislamiento de dermatofitos zoonóticos en la muestra de felinos del área urbana del Gran Mendoza fue del 13,3%, mayor a la esperada. M. canis fue el dermatofito más frecuentemente aislado(AU)


Background. The cat, considered the main reservoir of Microsporum canis, lives in urban areas, and also plays an important role in the emergence of dermatomycoses. Aims. To determine and analyse the frequency of zoonotic dermatophytes in a sample of cats in an urban area of the Gran Mendoza region. Methods. The animals selected were household cats and cats less than one year old that came from shelters and kennels from urban areas in the Gran Mendoza region. A total of 45 samples from cats with and without dermatological lesions were analysed. These samples were collected through skin scraping, hair removal and Mackenzie brush, respectively. Direct observation was made with KOH and glycerol after heat exposure. Samples were cultured on Sabouraud and Lactrimel agar slants with chloramphenicol and cycloheximide for 30 days. Results. The frequency of dermatophytes isolated in this preliminary study was 13.3%. There were not statistically significant differences by source, age, sex, race or dermatological condition. Zoonotic dermatophytes were found in 2 household cats out of the 21 that had direct contact with children or the elderly. M. canis was isolated in 83.3% cases. Conclusions. The frequency of isolation of zoonotic dermatophytes in the sample of cats in an urban area of the Gran Mendoza region was 13.3%, a value higher than expected. M. canis was the most isolated species(AU)

BACKGROUND: The cat, considered the main reservoir of Microsporum canis, lives in urban areas, and also plays an important role in the emergence of dermatomycoses. AIMS: To determine and analyse the frequency of zoonotic dermatophytes in a sample of cats in an urban area of the Gran Mendoza region. METHODS: The animals selected were household cats and cats less than one year old that came from shelters and kennels from urban areas in the Gran Mendoza region. A total of 45 samples from cats with and without dermatological lesions were analysed. These samples were collected through skin scraping, hair removal and Mackenzie brush, respectively. Direct observation was made with KOH and glycerol after heat exposure. Samples were cultured on Sabouraud and Lactrimel agar slants with chloramphenicol and cycloheximide for 30 days. RESULTS: The frequency of dermatophytes isolated in this preliminary study was 13.3%. There were not statistically significant differences by source, age, sex, race or dermatological condition. Zoonotic dermatophytes were found in 2 household cats out of the 21 that had direct contact with children or the elderly. M. canis was isolated in 83.3% cases. CONCLUSIONS: The frequency of isolation of zoonotic dermatophytes in the sample of cats in an urban area of the Gran Mendoza region was 13.3%, a value higher than expected. M. canis was the most isolated species.
