Scedosporium species rank the second among the filamentous fungi colonizing the airways of patients with cystic fibrosis (CF), after Aspergillus fumigatus. In CF, these fungi may cause various respiratory infections similar to those caused by A. fumigatus, including bronchitis and allergic broncho-pulmonary mycoses. Diagnosis of these infections relies on the detection of serum antibodies using crude antigenic extracts. However, many components of these extracts are common to Scedosporium and Aspergillus species, leading to cross-reactions...

BACKGROUND: Orbital apex syndrome is a localized type of orbital cellulitis, where mass lesions occur at the apex of the cranial nerves. Although nasal septal abscess is uncommon, the organism most likely to cause nasal septal abscess is Staphylococcus aureus, and fungal septal abscesses are rare. Here we present an extremely rare and serious case of orbital apex syndrome secondary to fungal nasal septal abscess caused by Scedosporium apiospermum in a patient with uncontrolled diabetes...

The genus Scedosporium, which comprises at least five clinically relevant species, i.e. Scedosporium apiospermum, Scedosporium boydii, Scedosporium aurantiacum, Scedosporium dehoogii and Scedosporium minutisporum, ranks the second among the filamentous fungi colonizing the airways of patients with cystic fibrosis (CF). This colonization of the airways is thought to contribute to the inflammatory reaction leading to a progressive deterioration of the lung function. Additionally, these colonizing fungi may lead to severe disseminated infections in case of lung transplantation...

By feeding various amino acids to the marine fungus Scedosporium apiospermum F41-1, 22 diverse alkaloids, including 14 new compounds, were obtained. Scedapins A-E (1-5) possess a rare skeleton of a pyrazinoquinazolinedione and an imidazoindolone/indolone linked by a tetrahydrofuran ring. Scedapin C (3) is the first example of fumiquinazoline that contains an aminosulfonyl group. Their structures were determined by HRMS, NMR, ECD calculations and X-ray single-crystal diffraction analysis. The biosynthetic pathways of fumiquinazolines 1-18 were proposed...

Fungal respiratory colonization of cystic fibrosis (CF) patients emerges as a new concern; however, the heterogeneity of mycological protocols limits investigations. We first aimed at setting up an efficient standardized protocol for mycological analysis of CF sputa that was assessed during a prospective, multicenter study: "MucoFong" program (PHRC-06/1902). Sputa from 243 CF patients from seven centers in France were collected over a 15-month period and submitted to a standardized protocol based on 6 semi-selective media...

The Scedosporium apiospermum species complex is an emerging filamentous fungi that has been isolated from environment. It can cause a wide range of infections in both immunocompetent and immunocompromised individuals. We aimed to study the genetic variation and relationships between 48 strains of S. apiospermum sensu stricto isolated from soil in Bangkok, Thailand. For PCR, sequencing and phylogenetic analysis, we used the following genes: actin; calmodulin exons 3 and 4; the second largest subunit of the RNA polymerase II; ß-tubulin exon 2-4; manganese superoxide dismutase; internal transcribed spacer; transcription elongation factor 1α; and beta-tubulin exons 5 and 6...

In recent years, the development of extracorporeal membrane oxygenation (ECMO) technology has led to its extensive use in clinical practice. In particular, ECMO can play an important role in cardiopulmonary resuscitation (CPR). The American Heart Association CPR guidelines recommend its use in patients with cardiac arrest due to reversible disorders, along with high-quality CPR. This is called extracorporeal cardiopulmonary resuscitation (ECPR). However, it is important to be aware of the possibility of infection-related complications...

Scedosporium apiospermum is known to be a fungal pathogen affecting immunocompromised as well as non-immunodeficient patients. Although this fungus is found rarely, an infection can lead to severe and even fatal disease. Here, we describe the case of a 41-year-old female who developed multiple Scedosporium apiospermum brain abscesses after near-drowning with aspiration of contaminated mud and water. She showed various neurological symptoms. The patient recovered after removal of abscesses in combination with long-term antifungal treatment...

The airways of patients with cystic fibrosis (CF) are frequently colonized by various filamentous fungi, mainly Aspergillus fumigatus and Scedosporium species. To establish within the respiratory tract and cause an infection, these opportunistic fungi express pathogenic factors allowing adherence to the host tissues, uptake of extracellular iron, or evasion to the host immune response. During the colonization process, inhaled conidia and the subsequent hyphae are exposed to reactive oxygen species (ROS) and reactive nitrogen species (RNS) released by phagocytic cells, which cause in the fungal cells an oxidative stress and a nitrosative stress, respectively...

BACKGROUND: Fungi of the genus Scedosporium are emerging pathogens responsible for severe infections in lung transplant recipients. These infections are associated with poor prognosis and some centers consider now Scedosporium species colonization as a contraindication to lung transplantation (LT) even though no published evidence demonstrates that Scedosporium species colonization is associated with higher morbidity or mortality after LT. METHODS: Here, we aim to describe characteristics and outcome of cystic fibrosis (CF) lung transplant recipients colonized with Scedosporium species in a single center over a 15-year period...

A 5-year-old, spayed female, Basset Hound was referred for evaluation of a urinary bladder mass. Ultrasonographic images revealed a large, inhomogeneous, hypoechoic mass associated with the dorsal wall of the neck of the urinary bladder and left ureter. Partial cystectomy and left ureteral reimplantation were performed. Histopathology showed a severe inflammatory mass lesion forming multiple granulomas. A DNA sequencing test revealed Scedosporium apiospermum as the causative agent. Susceptibility tests on the isolated strain indicated susceptibility to voriconazole...

Species of the Scedosporium apiospermum complex are the second most frequent filamentous fungi after Aspergillus fumigatus that can be found in cystic fibrosis (CF). Mixed colonisation by S. apiospermum complex and A. fumigatus is also quite common. In this study we summarise all CF patients who were colonised by S. apiospermum complex during their childhood and we present two CF patients who were treated as fungal bronchitis due to S. apiospermum complex. The medical records of 400 CF patients were reviewed in order to identify those with positive respiratory cultures for S...

BACKGROUND: Scedosporium apiospermum is an emerging opportunistic filamentous fungus, which is notorious for its high levels of antifungal-resistance. It is able to cause localized cutaneous or subcutaneous infections in both immunocompromised and immunocompetent persons, pulmonary infections in patients with predisposing pulmonary diseases and invasive mycoses in immunocompromised patients. Subcutaneous infections caused by this fungus frequently show chronic mycetomatous manifestation...

We hypothesised that anthropogenic influences impact the filamentous fungi community structure and that particular species or species patterns might serve as markers to characterise ecosystems. This study aimed to describe the filamentous fungi community structure in various biotopes along the Mediterranean shore that were exposed to various levels of anthropogenic influence. We sampled filamentous fungi from yellow-legged gull faecal samples at five study sites along the Mediterranean littoral in southern France...

Scedosporium apiospermum, an ubiquitous filamentous fungus, a known cause of mycetoma, is emerging as an opportunistic pathogen in immunocompromised individuals. We report a case of painful foot abscess in a renal allograft recipient on immunosuppressive therapy, which was clinically diagnosed as a suppurative bacterial abscess. Pus was aspirated, which showed septate, branching hyphal elements and culture on Sabouraud's dextrose agar yielded S. apiospermum, which was identified based on its macroscopic and microscopic features...

Lung infections with multiresistant pathogens are a major problem among patients suffering from cystic fibrosis (CF). N-Chlorotaurine (NCT), a microbicidal active chlorine compound with no development of resistance, is well tolerated upon inhalation. The aim of this study was to investigate the in vitro bactericidal and fungicidal activity of NCT in artificial sputum medium (ASM), which mimics the composition of CF mucus. The medium was inoculated with bacteria (Staphylococcus aureus, including some methicillin-resistant S...
