Mycosis and nocardiosis implantation: Sporotrichosis, Chromoblastomycosis, Mycetomas and Nocardiosis. Casuistics in the Central Laboratory of Public Health, Paraguay, period 1997-2019

Abstract

Introduction: sporotrichosis, chromoblastomycosis and mousetomas (implantation mycosis) and cutaneous nocardiosis are mainly caused by traumatic inoculation of fungi and bacteria from the environment. They are difficult to manage due to complications and little difficulty in treatment due to the late consultation of the patients. Objectives: to determine the demographic characteristics, clinical presentation of cases and identification of the causative agents of implantation mycosis and cutaneous nocardiosis from the records of the Mycology section of the Central Laboratory in the period 1997-2019. Methodology: retrospective descriptive observational study of files of the samples of patients who attended the Central Laboratory of Public Health during the study period. Results: 11 patients were found with sporotrichosis (Sporothrix schenkii complex), 21 with chromoblastomycosis (Fonsecae pedrosoi complex 47.6%, Phialophora verrucosa 4.7%), 4 mice (Scedosporium apiospermum, Acremonium kiliensi, Fusarium solani and Nocardia brasiliens) and 7 cutaneous nocardiosis (3 Nocardia brasiliensis, 2 Nocardia farcinica, 1 Nocardia transvalensis and 1 Nocardia sp.). A clinical presentation and the departments of origin of the patients are mentioned. Conclusions: these mycoses have an impact on public health and the focus for the actions of the government and non-governmental foundations should be aimed at training, diagnostic tests, availability of antifungals and information to the population.
