Backgroundand study aims: Dermatophytes are filamentous fungi characterized by their increased affinity to the keratin of the skin and phanera, and represent the main etiological agent of onychomycosis. The objective of this work is to identify the epidemiological and mycological profile of dermatophyte onychomycoses diagnosed at the laboratory of parasitology and mycology of the Hassan II university hospital of Fez. Patients and Methods:This is a retrospective descriptive study conducted in the laboratory of parasitology mycology of the Hassan II University Hospital of Fez including patients referred for mycological nail sampling during a period of 6 years from November 2015 to October 2021.The identification of the different species of dermatophytes responsible for onychomycosis was based on the observation of macroscopic and microscopic aspects of the colonies.Results: Of these 1673 patients, 460 cases of dermatophyte onychomycosis were confirmed with a prevalence of 27.5%. The age ranged from 9 to 87 years with an average age of 47.94 years. The disease was more common in women than in men, with a sex ratio of 0.63. Localization on the feet was predominant with a percentage of 93.7%. Trichophyton rubrum was the commonest dermatophyte isolated (95.7%), followed by Trichophyton mentagrophytes var interdigitalis (3.3%), Trichophyton verrucosum (0.7%), Trichophyton soudanense (0.2%), and Epidermophyton floccosum (0.2%). Conclusion: Trichophyton rubrum is the genus most involved in dermatophyte onychomycosis in accordance with the data in the literature. This work emphasizes the contribution of mycological examination in the confirmation of the fungal origin of nail diseases, thus orienting the treatment.
Keratitis is a frequent pathology in everyday ophthalmology, whose etiologies are dominated by bacterial origin. The mycotic origin is a rare cause, and the prognosis is usually reserved, given the delay in diagnosis, mainly due to self-medication. We present a case report concerning a 60 year old patient who presented a mycotic corneal abscess due to Alternaria sp . He presented a stromal infiltration of the cornea of the left eye on biomicroscopic examination. A swab of the abscess was performed for mycological study which came back positive for Alternaria sp . On the basis of the clinical manifestations and conducted examinition, a diagnosis of Alternaria mycotic keratitis was established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
