“…The results above are in agreement with another author who found them relevant to characterize medically important Herpotrichiellaceous fungi (3). The "in vitro" metabolism has shown to be an important tool for the understanding of the biology and ecology of these agents (1,4,5,17).…”

“…Growth and fermentative abilities were tested in duplicate and with blanks, according to van der Walt and Yarrow modified (4). Assimilation tests were performed in liquid medium with tubes incubated in a nearly horizontal position, aerated through slow rocking (50 rpm approximately) and weekly examined for 21 days.…”

Herpotrichiellaceous fungi, common agents of chromoblastomycosis and phaeohyphomycosis, were searched in samples of rotten wood, leaf littler, bark and soil of the rhizosphere, collected in the Centro Nacional de Pesquisas de Florestas/EMBRAPA, Colombo, PR, Brazil. Morphological analyses of macro, optic and scanning electron microscopy, as well as the determination of the nutritional pattern of the isolated strains were carried out for a taxonomical study. In a total of 17 colonies, 3 isolates (17.6%) were identified as species of medical relevance: Cladophialophora bantiana (Sacc.) de Hoog et al., Fonsecaea pedrosoi (Brumpt) Negroni and Phialophora verrucosa Medlar. The identifications were based on the results of the analyses and on the comparison with CBS (Centraal Bureau voor Schimmelcultures) reference strains. This investigation revealed the saprophytic existence of species known as agents of chromoblastomycosis and phaeohyphomycosis. These diseases are considered autochthonous in the studied area.

“…The genus Cladosporium has been shown to be both morphologically and phylogenetically heterogeneous (18). On the basis of molecular data, the true human-pathogenic species C. bantiana, C. carrionii, and C. devriesii, characterized by their thermotolerance and the absence of conidiophores with pigmented conidial scars, were transferred to Cladophialophora (1,7,18).…”

Cladosporium Species Recovered from Clinical Samples in the United States

et al. 2015

bCladosporium species are ubiquitous, saprobic, dematiaceous fungi, only infrequently associated with human and animal opportunistic infections. We have studied a large set of Cladosporium isolates recovered from clinical samples in the United States to ascertain the predominant species there in light of recent taxonomic changes in this genus and to determine whether some could possibly be rare potential pathogens. A total of 92 isolates were identified using phenotypic and molecular methods, which included sequence analysis of the internal transcribed spacer (ITS) region and a fragment of the large subunit (LSU) of the nuclear ribosomal DNA (rDNA), as well as fragments of the translation elongation factor 1 alpha (EF-1␣) and actin (Act) genes. The most frequent species was Cladosporium halotolerans (14.8%), followed by C. tenuissimum (10.2%), C. subuliforme (5.7%), and C. pseudocladosporioides (4.5%). However, 39.8% of the isolates did not correspond to any known species and were deemed to comprise at least 17 new lineages for Cladosporium. The most frequent anatomic site of isolation was the respiratory tract (54.5%), followed by superficial (28.4%) and deep tissues and fluids (14.7%). Species of the two recently described cladosporiumlike genera Toxicocladosporium and Penidiella are reported for the first time from clinical samples. In vitro susceptibility testing of 92 isolates against nine antifungal drugs showed a variety of results but high activity overall for the azoles, echinocandins, and terbinafine.
