Six new species of Sporothrix from hardwood trees in Poland

Abstract

Sporothrix (Sordariales, Ascomycota) is a well-supported monophyletic lineage within the Ophiostomatales, species of which occur in a diverse range of habitats including on forest trees, in the soil, associated with bark beetles and mites as well as on the fruiting bodies of some Basidiomycota. Several species have also been reported as important human and animal pathogens. During surveys of insect- and wound-associated Ophiostomatales from hardwood trees in Poland, many isolates with affinity to Sporothrix were recovered. In the present study, six undescribed Sporothrix spp. collected during these surveys are characterized based on their morphological characteristics and multi-locus phylogenenetic inference. They are described as Sporothrix cavum, Sporothrix cracoviensis, S. cryptarchum, S. fraxini, S. resoviensis, and S. undulata. Two of the Sporothrix spp. reside in the S. gossypina-complex, while one forms part of the S. stenoceras-complex. One Sporothrix sp. is a member of lineage F, and two other species grouped outside any of the currently defined species complexes. All the newly described species were recovered from hardwood habitats in association with sub-cortical insects, wounds or woodpecker cavities. These species were morphologically similar, with predominantly asexual states having hyaline or lightly pigmented conidia, which produce holoblastically on denticulate conidiogenous cells. Five of the new taxa produce ascomata with necks terminating in long ostiolar hyphae and allantoid ascospores without sheaths. The results suggest that Sporothrix species are common members of the Ophiostomatales in hardwood ecosystems of Poland.

Sporotrichosis in Children: Case series and Narrative Review

“…Sporotrichosis is the most globally prevalent among the implantation or subcutaneous fungal infections [1,2]. This disease was first described In Baltimore, USA, by Benjamin R. Schenck in 1898, and is a subacute to chronic fungal infection caused by thermally dimorphic fungal species which are classified in the genus Sporothrix spp., englobing 66 species and comprising environmental and pathogenic species [3][4][5][6][7][8][9]. Sporotrichosis can be transmitted to humans by plant fragments and organic substrates (sapronotic), but also though traumatic injuries related to several animals types, including cats, dogs, squirrels, insects, and fishes (zoonotic).…”

“…The genus Sporothrix belongs to the order Ophiostomatales and includes environmental fungi with a saprobic lifestyle in soil, plants, and decaying organic matter [1,2]. These fungi are widely distributed across a variety of climates in the world and populate a wide range of natural habitats, in particular bark, infructescences of Protea plants and wood of different trees [1,3,4]. Some species are also pathogenic for humans and other animals and cause a cutaneous or extracutaneous type of infection known as sporotrichosis [5].…”

“…Some species are also pathogenic for humans and other animals and cause a cutaneous or extracutaneous type of infection known as sporotrichosis [5]. This infection is generally caused by only four (Sporothrix schenckii, S. brasiliensis, S. globosa and S. luriei) of the 62 species currently listed in the genus [4]. The disease affects mainly humans and felines, sometimes involving thousands of individuals in large epidemics and/or epizootics [6][7][8].…”

Estudo da influência de vesículas extracelulares na resposta imune contra a esporotricose experimental

“…A este gênero atualmente pertencem cerca de 56 espécies já descritas, onde há relatos de algumas destas espécies apresentando envolvimento com infecções em humanos e animais domésticos, como o Sporothrix brasiliensis. As demais espécies relatadas são: Sporothrix schenckii, Sporothrix globosa, Sporothrix luriei Sporothrix mexicana, Sporothrix chilensis e Sporothrix pallida (LÓPEZ-ROMERO et al, 2011;MARIMON et al, 2007;OSTAFIŃSKA et al, 2021).…”
