    Introductions

    fused with secondary skin infections caused by systemic fungi treated below.

    Dermatophyte infections of the dermis

    Dermatophytes are normally con!ned to cutis, hair and nails, but occasionally the dermis is involved.

    Majocchi’s granuloma. Perifollicular granulomatous in"ammation. #e dermatophyte may be present in the cutis, but also deeper skin layers are involved.

    Kerion (pseudomycetoma). Subcutaneous, elevated, spongy lesion by dermatophytes with local necrosis and with presence of hyphae or grain-like structures.

    Non-ulcerative infections by diverse fungi

    #ese concern local, non-ulcerative infections caused by a variety of fungi. #e fungus is present in the form of septate hyphae or hyphal elements. In the case of hy-phomycotic cysts the a$ected area is surrounded by a !brous, collagenous secretion of the host, and hence no

    in"ammation occurs. According to the appearance of the causative agent as seen in native preparations, the follow-ing subdivision is made:Hyalohyphomycosis. #e fungal elements are colourless.Phaeohyphomycosis. #e fungal elements are melanised (special staining often necessary).

    Chromoblastomycosis

    #e disease occurs mostly on the extremities and is char-acterized by localized, slowly expanding lesions. Super!-cial, warty to cauli"ower-like tumours and deformations develop, due to hyperkeratosis and acanthosis. #e le-sions are greyish, crusted and dry in appearance. #e fun-gus occurs as dark, muriform cells in the tissue. Causative agents: Fonsecaea monophora, F. nubica, F. pedrosoi, Clado-phialophora carrionii, Phialophora verrucosa, Rhinocladiella aquaspersa. #e following types can be distinguished, of which several may occur in the same patient (adapted from Queiroz Telles et al., 2009):Nodular. Moderately elevated, fairly soft, dull to pink violaceous growth. Surface smooth, verrucous or scaly. With time lesions may gradually become tumorous.

    Phylum Basidiomycota

    #e life cycle of a prototypical basidiomycete is depicted. #e thallus consists of a septate, dikaryotic mycelium, often provided with clamp connections; these are bridges between adjacent cells to provide each of them with a nucleus derived from one of the parent strains. #e septa are perforated by a single, central pore. #e wall of the pore canal is often characteristically swollen; such a structure is called a dolipore. Spores each produce a short-lived, haploid myce-lium. Cells of suitable mating type show plasmogamy, but karyogamy is postponed. Consequently a heterokaryon with clamp connections is formed. #is condition is maintained during the major part of the life cycle, including fruitbody production. Karyogamy, immediately followed by meiosis, takes place in the basidium, which produces meiospores (basidiospores) exogenously, the spores often being forcibly discharged.

    Colony characteristicsColonies (PDA) with slow to moderate growth, cream-co-loured to tan.

Arthroconidia 1-celled, hyaline, smooth-walled, cylindrical, with truncate ends, 2.5-9.0 × 1-2 µm, dry. Trichosporiella-like synanamorph forming solitary, (sub)spherical, thin- and smooth-walled, hyaline conidia, 2-4 × 2-3 µm, formed laterally and sessile on undi$erenti-ated hyphae. Some isolates produce intercalary or termi-nal chlamydospores with smooth or slightly rugose walls, usually hyaline to subhyaline but occasionally brown giv-ing a dark pigmentation to the colony. Very rarely imma-ture ascomata submerged in the agar are produced.

    PathogenicityRG-1, BSL-2. Cochet (1939) already reported the fungus

    from onychomycosis, which is a main pathology (Sugiu-ra & Hironaga, 2010). Tewari & Macpherson (1968) ob-served neurotropism in arti!cial inoculation. Pichon et al. (2008) reported a cerebral case extending from the sinus in an alcoholic patient, Chin-Hong et al. (2001) a menin-gitis secondary to sinusitis in an AIDS patient, and Denis et al. (2016) a fungemia in a CF patient. Cases of keratitis were reported by Perlman & Binns (1997), #omas et al. (2011), Ramli et al. (2013), Chow et al. (2014) and Biser et al. (2004), ophthalmitis by Xi et al. (2004), endocardi-tis (de Diego Candela et al., 2010), a pulmonary infection (Vos et al., 2012) and a mycetoma by Degrave et al. (1997). A traumatic infection was reported by Boan et al. (2012). Two infections in immunocompromised patients were presented by Delage et al. (1998). #e species is soilborne.

    Recommended barcoding gene: rDNA ITS. For phylogenetic reasons, several species of Trichosporon were transferred to Apiotrichum (Liu et al., 2015); see also the phylogenetic tree of Trichosporon, where also a key to Trichosporon species and relatives is provided. Trichosporon mycotoxinovorans has been reported from lungs of patients with cystic !brosis (Hickley et al., 2009; Hirschi et al., 2012; Shah et al., 2014), but pathology has not been proven.

    Apiotrichum domesticum (Sugita et al.) Yurkov & Boekhout

    Colony characteristicsColonies (YM agar) yellowish wrinkled moist, with undu-late border.

    MicroscopyCells (YM broth) spherical or ovoidal, 3.7-4.8 × 5.2-12.8 µm; pseudo- and septate hyphae present, falling apart into arthroconidia.

    SerologyAmong the Trichosporon species, Ikeda et al. (1996) typi-!ed the species as serotype III.

    PathogenicityRG-1, BSL-1. #e species, originally isolated from the

    house of a summer-type hypersensitivity pneumonitis patient in Japan (Sugita et al.,1995, 2004), is rare. It was also isolated from a cat with chronic cystitis (Sakamoto et al., 2001).

    Colony characteristicsColonies on CZA at 25°C attaining diameters of 4-5 cm in 10 days, velvety, somewhat zonate, consisting of a fairly compact white basal mycelium. Conidial heads in slightly greyish black-brown shades, borne on long conidiophores; reverse white; exudate and odor lacking. Colonies on MEA at 25°C growing rapidly, reaching 6 cm in diam in 10 days, thin, plane, velvety, indistinctly zonate, heavily sporulat-ing in very dark brown shades; reverse uncoloured.

    MicroscopyConidial heads spherical to radiate, mostly 200-300 µm. Conidiophores smooth, long and coarse, commonly 15-20µm diam, usually lightly coloured in brown shades, thin-walled; vesicles spherical, rather variable in size, most commonly 40-60 µm diam, fertile over their entire surface. Conidia spherical with hyaline echinulations when !rst formed, becoming progressively darker and rougher and !nally appearing longitudinally striate from conspicuous bars of colouring material, mature conidia somewhat horizontally "attened, 3.0-3.5 µm in diam. Sclerotia produced in some strains, occasionally dominating the colony appearance, (sub)spherical, cream coloured at !rst

    then pinkish bu$ and sometimes darkening to almost black in age, commonly 500-800 µm in diam.

    Molecular diagnosticsAspergillus tubingensis can be distinguished from other related members of Aspergillus section Nigri using mtD-NA and rDNA RFLP data (Varga et al., 1993, 1994), and by sequence analysis of beta-tubulin or calmodulin genes (Samson et al., 2007b).

    PathogenicityRG-1, BSL-1. Agent of invasive aspergillosis (Kano et al., 2008a; Howard et al., 2008), of osteomyelitis (Bathoon et al., 2013) and of keratitis (Kredics et al., 2009). A cu-taneous infection nwas reported by Frias-De-Leon et al. (2018). #e species appears to be relatively commonly in-volved in pulmonary disorders (Gautier et al., 2016).
