“…In particular, Scopulariopsis brevicaulis, a geophilic fungus, has been associated with dermatophytosis in both animals (dogs and horses) and humans inducing onychomycosis and hyalohyphomycosis. In addition, such a fungus has been identified as a causative agent of onychomycosis, panophthalmia, granulomas and generalised infection in humans (Vangeel et al , Wu et al , Petanovic et al 2010). In guinea pigs, Scopulariopsis species has been isolated in 13% of the population screened by Vangeel et al ().…”

“…Little is known about the health effects of these fungi, although several species seem to be able to cause human onychomycosis and superficial tissue infections ( e.g . Tosti et al., 1996, Wu et al., 2009). Rare cases of more severe diseases are reported, but only in immunocompromised patients ( e.g .…”

Scopulariopsis-like species are often reported from the indoor environment, as well as from clinical samples. The lack of type isolates and thorough phylogenetic studies in the Microascaceae hampered the correct identification of these isolates. Based on recent phylogenetic studies, which resulted in multiple name changes, the aim is to molecularly identify the Scopulariopsis and scopulariopsis-like species which occur in the indoor environment and give an overview of the current species in these genera and their habitats. Strains from the CBS culture collection were supplemented with almost 80 indoor strains of which the internal transcribed spacer 1 and 2 and intervening 5.8S nrDNA (ITS), beta-tubulin (tub2) and translation elongation factor 1-alpha (tef1) gene regions were sequenced for phylogenetic inference. The multi-gene phylogenies recognise 33 Microascus species and 12 Scopulariopsis species and showed that the recently established genus Fuscoannellis, typified by Scopulariopsis carbonaria, should be synonymized with the genus Yunnania. Seven new Microascus species, four new Scopulariopsis species, and one new Yunnania species, are described, and a new name in Microascus and two new name combinations (one in Microascus, and one in Yunnania) are proposed. In the indoor environment 14 Microascus species and three Scopulariopsis species were found. Scopulariopsis brevicaulis (22 indoor isolates) and Microascus melanosporus (19 indoor isolates) are the most common indoor species, in number of isolates, followed by M. paisii (8 indoor isolates) and S. candida (7 indoor isolates). A genus phylogeny based on the ITS, tef1 and the large subunit 28S nrDNA (LSU) of the type or representative isolates of all here recognised species is provided depicting all species habitats. No correlation between phylogenetic relationship and habitat preference could be observed. Ten species which are found indoor are also found in relation with human-derived samples. A table showing recent name changes and a key to common species of Scopulariopsis and scopulariopsis-like genera found indoors is included.

“…Despite the fact that S. brevicaulis is not considered to be a typical skin pathogen, several case reports of skin infections due to this species have been reported. Scopulariopsis brevicaulis has been described as an aetiological agent of skin infections of: face [ 16 , 17 , 38 , 39 ], lower limbs (including foot) [ 40 , 41 ], and trunk [ 42 ].

“…Fungi from the genus Scopulariopsis occure in soil, air, organic waste, food, feed, plants, animals, and humans [ 1 – 6 ]. In humans they have been mainly associated with superficial infections of keratinized tissues, especially with onychomycoses [ 7 – 17 ]. They have also been described as a cause of cutaneous, subcutaneous, and deep tissues mycoses, e.g.…”

IntroductionIn the genus Scopulariopsis, Scopulariopsis brevicaulis is the most common aetiological agent of infections in humans. It usually affects nails and is one of the commonest moulds associated with onychomycoses. Other forms of infections (skin, subcutaneous, deep tissues, and disseminated infections) have also been described.AimTo examine the prevalence of S. brevicaulis in clinical materials obtained from patients suspected of keratinized tissues mycoses.Material and methodsThe analysis of the prevalence of S. brevicaulis in clinical specimens was based on mycological test's results carried out for patients who were referred with a suspicion of superficial mycoses to the Department of Mycology, Chair of Microbiology, Jagiellonian University Medical College from 1992 till 2012.ResultsIn the years 1992–2012 16,815 clinical samples (nail scrapings, nail swabs, skin scrapings, skin swabs, hair) were collected. Pathogenic fungi were detected in 7193 samples and S. brevicaulis was present in 255 (3.5%). The prevalence of S. brevicaulis in males and females was comparable. The species was most often isolated from toenails (80%), both from males and females. In the analysed period we observed a decrease in the prevalence of S. brevicaulis. In most cases (60%) S. brevicaulis occurred alone in 40% of S. brevicaulis positive cultures, other fungi were also isolated. The fungi most frequently isolated with S. brevicaulis were Trichophyton rubrum, T. mentagrophytes, Penicillium sp., Candida sp., and Aspergillus sp.ConclusionsScopulariopsis brevicaulis is not a common cause of superficial fungal infections of keratinized tissues, but is a typical mould associated with toenail onychomycosis. A proper identification of this species in onychomycoses is essential for the implementation of effective antifungal therapy.
