RESUMO
ABSTRACT Objective. The dermatophytes are keratinophilic fungi, of importance in public health because of their anthropozoophilic nature. Given the increasing acquisition of exotic animals as pets and the scarce studies on the state of colonization by dermatophytes on these animals; we raised the objective of determine the presence of dermatophytes in clinically healthy rabbits (Oryctolagus cuniculus) from pet stores in Santiago, Chile. Materials and Methods. 42 clinically healthy rabbits were studied. Clinical specimens were obtained from the hairy mantle and cultivated on Sabouraud glucose agar and dermatophyte test medium (DTM™); the identification of the fungal isolates was performed using classic mycological procedures that included direct microscopic examination and the analysis of micromorphological features on culture. Results. Of the total number of rabbits studied, three (7.1%) presented colonization by dermatophytes, being more frequent in males and in those animals that coexisted with Guinea Pigs. The species identified in all three cases was Trichophyton mentagrophytes. Conclusions. This study evidence colonization by dermatophytes in domestic rabbits, important information for veterinarians and owners of pets, at the time of being in contact with this animal species.
RESUMEN Objetivo. Los dermatofitos son hongos queratinofílicos, de importancia en salud pública por su rol antropozoofílico. Dado el aumento en la adquisición de animales exóticos como mascotas y los escasos estudios sobre el estado de colonización por dermatofitos en estos animales, nos planteamos el objetivo de determinar la presencia de dermatofitos en conejos (Oryctolagus cuniculus) clínicamente sanos procedentes de tiendas de mascotas en Santiago de Chile. Materiales y Métodos. Se estudiaron 42 conejos clínicamente sanos. Las muestras clínicas se obtuvieron desde el manto piloso y cultivadas en agar Sabouraud glucosado y dermatophyte test medium (DTM®). La identificación del agente aislado fue realizada por procedimientos micológicos clásicos que incluyeron examen microscópico directo y cultivo. Resultados. Del total de conejos estudiados, tres (7,1%) presentaron colonización por dermatofitos, siendo más frecuente en machos y en aquellos animales que convivían con cuyes. La especie identificada en los tres casos fue Trichophyton mentagrophytes. Conclusiones. Este estudio evidencia la colonización por dermatofitos en conejos domésticos, información importante para médicos veterinarios y propietarios de mascotas, al momento de estar en contacto con esta especie animal.

Antecedentes: Los dermatofitos son hongos patógenos que pueden formar parte de la microbiota de mamíferos como perros, gatos y roedores, que pueden ser fuente y vehículo de transmisión a otros hospederos, incluyendo al hombre. En nuestro medio, existe un aumento sostenido en la incorporación de cuyes (Cavia porcellus) como mascota, sin contar con estudios locales que evidencien la colonización de dermatofitos. Objetivos: Determinar la presencia de dermatofitos en cuyes clínicamente sanos, mantenidos en tiendas de mascotas en la ciudad de Santiago de Chile. Métodos: Se incluyeron en el estudio 52 animales clínicamente sanos, muestreados mediante el método de Mariat y Tapia (1966). Para el cultivo de las muestras y la identificación de los agentes aislados se siguieron los procedimientos micológicos clásicos. Resultados: Del total de cuyes, 4 (7,7%) presentaron colonización por dermatofitos; las especies aisladas fueronTrichophyton mentagrophytes (3 casos) y Trichophyton verrucosum (un caso). Conclusiones: Este estudio evidencia, por primera vez en Chile, que los cuyes pueden ser colonizados por dermatofitos, lo cual debe alertar a los administradores de las tiendas de mascotas y a los médicos veterinarios y humanos, para tenerlo presente en el momento de adquirir o atender a este tipo de mascota en la clínica veterinaria (AU)
Background: Dermatophytes are pathogenic fungi that can be present in the flora of mammals, such as dogs, cats and rodents, which can be a source and transmission vehicle to other hosts, including humans. In Chile, there is a steady increase of acquiring guinea pigs (Cavia porcellus) as pets, with no local studies on their colonization by dermatophytes. Objective: To determine the presence of dermatophytes on clinically healthy guinea pigs, kept in pet stores in Santiago, Chile. Methods: A total of 52 clinically healthy animals were studied using the method by Mariat and Tapia (1966). The specimen culture and identification of the dermatophytes were performed using classical mycological procedures. Results: Four guinea pigs (7.7%) out of 52 were colonized by dermatophytes, and were identified as Trichophyton mentagrophytes (3 cases) and Trichophyton verrucosum (one case). Conclusion: This study shows, for the first time in Chile, that guinea pigs can be colonized by dermatophytes, which should alert administrators of pet stores, veterinarians and physicians, to keep this in mind when purchasing or looking after this type of pet in a veterinary office (AU)
