Cladosporium spp: Morfologia, infecções e espécies patogênicas

Abstract

ResumoO gênero Cladosporium spp compreende grande número de fungos dematiáceos com distribuição mundial e que estão entre os fungos de ambiente mais comuns. São frequentemente isolados como contaminantes, no entanto, algumas espécies são patogênicas e toxigênicas para os seres humanos, estando associados a infecções superficiais da pele e dos tecidos moles e incluem sepse disseminada com elevada mortalidade. Cladoporium spp são aero-alérgenos e causam graves doenças alérgicas do trato respiratório, bem como lesões intrabrônquicas. Atualmente, as espécies de Cladosporium spp de interesse médico associadas com doença humana são C. cladosporioides, C. herbarum, C. oxysporum e C. sphaerospermum. No caso de infecções por Cladosporium spp, a terapia é prolongada e varia de acordo com a síndrome clínica. Sendo essencial o conhecimento a cerca desse gênero, para melhor diagnóstico e tratamento adequado. Esta revisão de literatura teve como objetivo reunir informações sobre as características gerais e morfológicas, patologias, aspectos clínicos e principais espécies patogênicas das infecções causadas por esse gênero.

Cladosporium spp: Morphology, infections and pathogenic species AbstractThe genus Cladosporium spp comprises a large number of dematiaceous fungi with a world-wide distribution and are among the most common air-borne fungi. They are frequently isolated contaminants and some species are pathogenic and toxigenic to humans and are associated with superficial infections of the skin and soft tissues, including disseminated sepsis with high mortality. In addition, Cladoporium spp. are aero-allergens and cause serious allergic diseases of the respiratory tract, as well as intrabronchial lesions. Currently, the Cladosporium spp species of medical interest associated with human disease are C. cladosporioides, C. herbarum, C. oxysporum and C. sphaerospermum. In the case of Cladosporium spp infections, the therapy is prolonged and varies according to the clinical syndrome. Knowledge about this genre is essential for better diagnosis and appropriate treatment. This literature review to gather information about the general and morphological characteristics, pathologies, clinical aspects and main pathogenic species of the infections caused by this genus.

Identification of keratinophilic fungi in the coat microbiota of anteaters retained in captivity in two Brazilian Zoos

“…They are considered among the fungi with the highest concentration in the atmosphere, mainly in tropical and sub-tropical climate regions (Zoppas et al, 2011). Menezes et al (2017) depicted the fungi of this genus as endowed with great adaptive capacity, capacity for contamination and colonization of different environments, as it was possible to verify in this study, where this genus was isolated from the integument of several species of anteater studied. As observed by means of other authors, in this research, the macro morphological evaluation of Cladosporium spp.…”

“…However, there are already references to the pathogenic power of these fungi. Menezes et al (2017) reported in their research that the genus Cladosporium spp. it can cause from epithelial lesions, such as keratitis, with organ involvement, to the development of brain abscesses (Oliveira et al, 2001).…”

Counting and identification of molds and yeasts in dry salted shrimp commercialized in Rio Branco, Acre, Brazil

“…Among microorganisms identified in this study, it is considered that Aspergillus, Penicillium and Fusarium are potential producers of mycotoxins, which can cause serious neurogenic, teratogenic, carcinogenic and immunosuppressive problems (Calvet et al, 2012;Sun et al, 2014;Kim et al, 2020). The Cladosporium, in turn, is generally considered a food contaminant, but some species are pathogenic to humans, related to skin infections, rhinosinusitis, brain abscess and septicemia (Menezes et al, 2017;Garcia et al, 2018;Ahn et al, 2019;Batra et al, 2019).…”

Physiological and Sanitary Attributes Evaluation of Organic Coriander Seeds Treated With Essential Oils

“…In the present work, these results were not observed with clove essential oil. According to Menezes et al (2017) the genus Cladosporium sp. comprises a large number of fungi with worldwide distribution and which are among the most common environmental fungi.…”
