Abstract
A case of allergic fungal sinusitis (AFS) due to Schizophyllum commune was reported. The pathogen was identified using molecular bioanalysis. The patient underwent the functional endoscopic sinus surgery followed by the radical maxillary sinusotomy with canine fossa trephine. This case suggested that complete surgery allowed optimal disease clearance for AFS caused by Schizophyllum commune.

Schizophyllum radiatum, an Emerging Fungus from Human Respiratory Tract. J Clin Microbiol 2016; 54:2491-7.

Abstract
Schizophyllum is an important genus of basidiomycetes that, apart from being of genetic and biotechnological interest, is also reported to be a plant and animal pathogen. Schizophyllum commune is the best-known species and the only one reported from clinical specimens thus far, being recovered mainly from the respiratory tract. The aim of this study was to determine the species diversity of 23 clinical isolates of Schizophyllum from the United States using multilocus phylogenetic analysis and their in vitro susceptibilities to six drugs. The markers used for sequencing were the internal transcribed spacer (ITS), a portion of the nuclear large subunit (LSU) of ribosomal DNA, the RNA polymerase II second-largest subunit (RPB2), and the translation elongation factor 1α (EF-1α) gene. The analyses revealed that 22 of the clinical isolates were in the Schizophyllum radiatum clade with high support values and 1 isolate was in the S. commune clade. This is the first report of this species in clinical samples. The two species mentioned above showed very similar morphological features in culture (i.e., white, cottony, unsporulated colonies composed of hyphae with clamp connections), making morphological discrimination between the two impossible. An epitype is designed for S. radiatum, and its sequences have been deposited in GenBank. The antifungal that showed the greatest in vitro activity against the strains tested was shown to be amphotericin B. In general, the strains of S. radiatum showed higher MICs than S. commune.

Abstract
There are three broad groups of non-Aspergillus moulds: the mucormycetes, the hyalohyphomycetes and the phaeohyphomycetes. Infections with these pathogens are increasingly reported, particularly in the context of increasing use of immunosuppressant agents and improved diagnostics. The epidemiology of non-Aspergillus mould infections varies with geography, climate and level of immunosuppression. Skin and soft-tissue infections are the predominant presentation in the immunocompetent host and pulmonary and other invasive infections in the immunocompromised host. The more common non-Aspergillus moulds include Rhizopus, Mucor, Fusarium and Scedosporium species; however, other emerging pathogens are Rasamsonia and Verruconis species, which are discussed in this article. Outbreaks of non-Aspergillus mould infections have been increasingly reported, with contaminated medical supplies and natural disasters as common sources. Currently culture and other conventional diagnostic methods are the cornerstone of diagnosis. Molecular methods to directly detect and identify mould pathogens in tissue and body fluids are increasingly used.

Abstract
Schizophyllum commune is a common basidiomycete fungus that is rarely involved in human disease. The medical records of patients operated on for fungal rhinosinusitis (FRS) in two University Hospitals between 2012 and 2014 were reviewed. Within the two-year survey, six female, and notably no male, patients were diagnosed with S. commune rhinosinusitis. Mean age was 44.6 years at diagnosis (30 to 68 years). Mean time between onset of symptoms and diagnosis was 8.5 months (2 to 12 months). All six patients were immunocompetent and had no particular host factor for FRS. S. commune was identified using MALDI-TOF mass spectrometry and identifications were confirmed via DNA sequence analysis. Chronic invasive fungal rhinosinusitis was diagnosed in three of our six patients. Based on histological findings, antifungal treatment was delivered in association with surgery. The basidiomycete fungus S. commune is an emerging cause of rhinosinusitis probably as a direct consequence of the recent technological progress in fungal identification methods (DNA sequencing and MALDI-TOF mass spectrometry).

Abstract
Schizophillum commune is an environmental fungus rarely causing human infections of diverse nature. Sinusitis occurs in immunocompromised persons and seldom in healthy subjects. Though easily isolated, the lack of awareness of its virulence is a bottleneck in the diagnosis of this infection. We report the first case of S. commune sinusitis with nasal polyps in an immunocompetent male from the sub-Himalayan region. The computerized tomography scan findings established the clinical diagnosis, and causative agent was confirmed as S. commune. A white, woolly mold with septate, hyaline hyphae and characteristic spicules but unclamped connections suggested a monokaryotic isolate. Patient was treated successfully with fiberoptic endoscopic sinus surgery, and no antifungal therapy was instituted. There was no recurrence at review after 1 year.

Abstract
We present a rare case of eosinophilic fungal rhinosinusitis with nasal polyps in a 32-year-old woman caused by basidiomycete fungus Schizophyllum commune. Diagnosis was done by the endoscopic nasal examination, computed tomography (CT) of the paranasal sinuses, the histopathological examination of polyps, the presence of eosinophils and fungal hyphae in nasal mucus and by the detection of S. commune by culture. The patient was successfully treated by combination of oral itraconazole and topical corticosteroid therapy combined with surgery. The pathogenesis and diagnosis of allergic fungal rhinosinusitis are also discussed.

Abstract
The filamentous basidiomycetous fungus, Oxyporus corticola, has not previously been reported in the human or veterinary medical literature. Identification of this organism as the etiologic agent of fungal osteomyelitis and multiorgan dissemination in a German shepherd dog was confirmed by comparison of ITS and D1/D2 sequences with known isolates.

Abstract
Abstract
Fungal rhinosinusitis (FRS) refers to a spectrum of disease ranging from benign colonization of the nose and sinuses by pathogenic fungi to acute invasive and fatal inflammation extending to the orbit and brain. FRS is classified into two categories: invasive and noninvasive. Invasive FRS may again be subcategorized into acute invasive (fulminant) FRS, granulomatous invasive FRS, and chronic invasive FRS; while noninvasive FRS is subcategorized into localized fungal colonization, sinus fungal ball and eosinophil related FRS (including allergic fungal rhinosinusitis, eosinophilic fungal rhinosinusitis). This classification is not without controversies, and intermediate and semi-invasive forms may also exist in particular patients. Acute invasive FRS is an increasingly common disease worldwide among the immunocompromised patients and caused most frequently by Rhizopus oryzae, and Aspergillus spp. Granulomatous invasive FRS has mostly been reported from Sudan, India, and Pakistan and is characterized by noncaseating granuloma formation, vascular proliferation, vasculitis, perivascular fibrosis, sparse hyphae in tissue, and isolation of A. flavus from sinus contents. Chronic invasive FRS is an emerging entity occurring commonly in diabetics and patients on corticosteroid therapy, and is characterized by dense accumulation of hyphae, occasional presence of vascular invasion, sparse inflammatory reaction, involvement of local structures, and isolation of A. fumigatus. While localized fungal colonization describes the most benign of all fungal sinusitis in the superficial nasal crusts, sinus fungal ball is a dense mycetoma like aggregate of fungal hyphae in diseased sinuses. Common in southern Europe, especially France, majority of them are sterile on culture while 30-50% may yield Aspergillus spp. The definitions and pathogenesis of the group of syndromes in eosinophil related FRS (AFRS, EFRS) are contentious and a matter of intense research among otolaryngologists, pathologists, immunologists and microbiologists. While dematiaceous fungi are the foremost initiators of these syndromes in the west, Aspergillus flavus is the predominant pathogen in India and the Middle-East.
