Abstract
BACKGROUND Scedosporium apiospermum (S. apiospermum) is a rare fungal pathogen that causes disseminated infections. It rarely affects immunocompetent individuals and has a poor prognosis. CASE PRESENTATION A 37-year-old woman presented with multiple lesions in the lungs, brain, and eyes, shortly after near drowning in a car accident. The primary symptoms were chest tightness, limb weakness, headache, and poor vision in the left eye. S. apiospermum infection was confirmed by metagenomic next-generation sequencing (mNGS) of intracranial abscess drainage fluid, although intracranial metastases were initially considered. After systemic treatment with voriconazole, her symptoms improved significantly; however, she lost vision in her left eye due to delayed diagnosis. CONCLUSION While S. apiospermum infection is rare, it should be considered even in immunocompetent patients. Prompt diagnosis and treatment are essential. Voriconazole may be an effective treatment option.

Abstract
Scedosporium apiospermum species complex are widely distributed fungi that can be found in a variety of polluted environments, including soil, sewage, and decaying vegetation. Those opportunistic pathogens with strong potential of invasion commonly affect immunosuppressed populations However, few cases of scedosporiosis are reported in immunocompetent individuals, who might be misdiagnosed, leading to a high mortality rate. Here, we reported an immunocompetent case of systemtic infection involved in lung, brain and spine, caused by S. apiospermum species complex (S. apiospermum and S. boydii). The patient was an elderly male with persistent fever and systemtic infection after near-drowning. In the two tertiary hospitals he visited, definite diagnosis was extremely difficult. After being admitted to our hospital, he was misdiagnosed as tuberculosis infection, before diagnosis of S. apiospermum species complex infection by the metagenomic next-generation sequencing. His symptoms were alleviated after voriconazole treatment. In the present case, the details associated with its course were reported and published studies on Scedosporium spp. infection were also reviewed, for a better understanding of this disease and reducing the misdiagnosis rate.

Abstract
A new antifungal compound, named N-demethyltyroscherin (1), was discovered from the static fungal cultured material of Scedosporium apiospermum FKJ-0499 isolated from a deep-sea sediment sample together with a known compound, tyroscherin (2). The structure of 1 was elucidated as a new analog of 2 by MS and NMR analyses. The absolute configuration of 1 was determined by chemical derivatization. Both compounds showed potent in vitro antifungal activity against clinically isolated Candida auris strains, with MIC values ranging from 0.0625 to 4 µg ml-1.

Abstract
The purpose is to assess the efficacy of rose bengal photodynamic antimicrobial therapy (PDAT) using different irradiation energy levels and photosensitizer concentrations for the inhibition of fungal keratitis isolates. Seven different fungi (Aspergillus fumigatus, Candida albicans, Curvularia lunata, Fusarium keratoplasticum, Fusarium solani, Paecilomyces variotii, and Pseudallescheria boydii) were isolated from patients with confirmed infectious keratitis. Experiments were performed in triplicate with suspensions of each fungus exposed to different PDAT parameters including a control, green light exposure of 5.4 J/cm2, 2.7 J/cm2 (continuous and pulsed), and 1.8 J/cm2 and rose bengal concentrations of 0.1%, 0.05%, and 0.01%. Plates were photographed 72 h after experimentation, and analysis was performed to assess fungal growth inhibition. PDAT using 5.4 J/cm2 of irradiation and 0.1% rose bengal completely inhibited growth of five of the seven fungal species. Candida albicans and Fusarium keratoplasticum were the most susceptible organisms, with growth inhibited with the lowest fluence and minimum rose bengal concentration. Fusarium solani, Pseudallescheria boydii, and Paecilomyces variotii were inhibited by lower light exposures and photosensitizer concentrations. Aspergillus fumigatus and Curvularia lunata were not inhibited by any PDAT parameters tested. Continuous and pulsed irradiation using 2.7 J/cm2 produced similar results. Rose bengal PDAT successfully inhibits the in vitro growth of five fungi known to cause infectious keratitis. Differences in growth inhibition of the various fungi to multiple PDAT parameters suggest that susceptibilities to PDAT are unique among fungal species. These findings support modifying PDAT parameters based on the infectious etiology.

Abstract
Scedosporium/Lomentospora species exist as saprophytic moulds that can potentially lead to serious infections in patients who have experienced near-drowning incidents. Scedosporium species are distributed across different regions of the world while Lomentospora prolificans has quite a restricted geographic distribution. We aimed to systematically review scedosporiosis cases after near-drowning, their clinical manifestations, underlying diseases, treatments, outcomes and its impact through disability-adjusted life years (DALYs). Five available sources were searched from 1 January 2007, to 20 April 2022. Thirty-eight studies, including 41 patients, were evaluated. Mean age was 33.6 ± 18.6 years (range 1-68), and 28 were male (68.3%). Central nervous system (CNS) dissemination predominated (36/41; 87.8%), presenting mainly as multiple brain abscesses (26/41; 63.4%), followed by lung involvement (22/41; 56.4%). Scedosporium apiospermum species complex was the most causative agent (38/41; 92.7%). Overall mortality was 51.2%. Half of the patients (18/37) were cured after receiving proper treatment, and in most cases, voriconazole alone or in combination with surgery or other antifungals caused survival. The mean survival time was 123 ± 27 days. Mean DALYs in 1980-2022 were 46.110 ± 3.318 (39.607-52.612). Time to diagnosis was estimated to be 120 days, and there was no association between time to diagnosis and outcome. Voriconazole is a potentially effective therapy, and combination of surgery and antifungal treatment may lead to more favourable outcome. Advances in early diagnosis and appropriate antifungal therapy may have contributed to reducing its mortality.

Abstract
Infections with Scedosporium spp. are emerging in the past two decades and are associated with a high mortality rate. Microbiological detection can be associated with either colonization or infection. Evolution from colonization into infection is difficult to predict and clinical management upon microbiological detection is complex. Microbiological samples from 2015 to 2021 were retrospectively analyzed in a single tertiary care center. Classification into colonization or infection was performed upon first microbiological detection. Clinical evolution was observed until July 2023. Further diagnostic procedures after initial detection were analyzed. Among 38 patients with microbiological detection of Scedosporium spp., 10 were diagnosed with an infection at the initial detection and two progressed from colonization to infection during the observation time. The main sites of infection were lung (5/12; 41.6%) followed by ocular sites (4/12; 33.3%). Imaging, bronchoscopy or biopsies upon detection were performed in a minority of patients. Overall mortality rate was similar in both groups initially classified as colonization or infection [30.7% and 33.3%, respectively (P = 1.0)]. In all patients where surgical debridement of site of infection was performed (5/12; 42%); no death was observed. Although death occurred more often in the group without eradication (3/4; 75%) compared with the group with successful eradication (1/8; 12.5%), statistical significance could not be reached (P = 0.053). As therapeutic management directly impacts patients' outcome, a multidisciplinary approach upon microbiological detection of Scedosporium spp. should be encouraged. Data from larger cohorts are warranted in order to analyze contributing factors favoring the evolution from colonization into infection.

Abstract
BACKGROUND Little is known about the short- and long-term healthcare costs of invasive Scedosporium/Lomentospora prolificans infections, particularly in patient groups without haematological malignancy. This study investigated excess index hospitalization costs and cumulative costs of these infections. The predictors of excess cost and length of stay (LOS) of index hospitalization were determined. These estimates serve as valuable inputs for cost-effectiveness models of novel antifungal agents. METHODS A retrospective case-control study was conducted at six Australian hospitals. Cases of proven/probable invasive Scedosporium/L. prolificans infections between 2011 and 2021 (n = 34) were matched with controls (n = 66) by predefined criteria. Cost data were retrieved from activity-based costing systems and analysis was performed from the Australian public hospital perspective. All costs were presented in 2022 Australian dollars (AUD). Median regression analysis was used to adjust excess costs of index hospitalization whereas cumulative costs up to 1.5 years follow-up were estimated using interval-partitioned survival probabilities. RESULTS Invasive Scedosporium/L. prolificans infections were independently associated with an adjusted median excess cost of AUD36 422 (P = 0.003) and LOS of 16.27 days (P < 0.001) during index hospitalization. Inpatient stay was the major cost driver (42.7%), followed by pharmacy cost, of which antifungal agents comprised 23.8% of the total cost. Allogeneic haematopoietic stem cell transplant increased the excess cost (P = 0.013) and prolonged LOS (P < 0.001) whereas inpatient death within ≤28 days reduced both cost (P = 0.001) and LOS (P < 0.001). The median cumulative cost increased substantially to AUD203 292 over 1.5 years in cases with Scedosporium/L. prolificans infections. CONCLUSIONS The economic burden associated with invasive Scedosporium/L. prolificans infections is substantial.

Abstract
The authors describe a case of nylon foil implant infection caused by Fusarium brachygibbosum , and Lomentospora prolificans following medial orbital wall fracture repair in the setting of postoperative nasal methamphetamine use. A 61-year-old male presented with OS pain and swelling after a physical assault on his face. A CT of maxillofacial bones without contrast showed a moderately comminuted fracture of the medial wall of the left orbit with depression of fracture fragments into the left ethmoid air cells. Six days after repair of the medial wall fracture, the patient returned with a new onset headache, OS pain, and swelling to the left medial canthal area. He reported snorting methamphetamine approximately 48 hours before his current presentation. CT imaging showed fat stranding and soft tissue density in the extraconal space adjacent to the left medial rectus muscle and chronic fracture deformity of lamina papyracea with approximately 4 mm of medial displacement of the fracture fragments. The patient showed little clinical improvement after 48 hours of intravenous antibiotics, which led to the removal of the nylon foil implant by a left orbitotomy. Intraoperative tissue cultures grew coagulase-negative Staphylococcus , F. brachygibbosum , and Lomentospora (Scedosporium) prolificans . The patient was subsequently transitioned to oral clindamycin 600 mg three times daily and voriconazole 200 mg two times daily. To the authors' knowledge, this is the first case report to document an association between snorted methamphetamine and a fungal infection of an orbital implant.

Abstract
Scedosporium apiospermum is a widespread, emerging, and multidrug-resistant filamentous fungus that can cause localized and disseminated infections. The initial step in the infection process involves the adhesion of the fungus to host cells and/or extracellular matrix components. However, the mechanisms of adhesion involving surface molecules in S. apiospermum are not well understood. Previous studies have suggested that the binding of fungal receptors to fibronectin enhances its ability to attach to and infect host cells. The present study investigated the effects of fibronectin on adhesion events of S. apiospermum. The results revealed that conidial cells were able to bind to both immobilized and soluble human fibronectin in a typically dose-dependent manner. Moreover, fibronectin binding was virtually abolished in trypsin-treated conidia, suggesting the proteinaceous nature of the binding site. Western blotting assay, using fibronectin and anti-fibronectin antibody, evidenced 7 polypeptides with molecular masses ranging from 55 to 17 kDa in both conidial and mycelial extracts. Fibronectin-binding molecules were localized by immunofluorescence and immunocytochemistry microscopies at the cell wall and in intracellular compartments of S. apiospermum cells. Furthermore, a possible function for the fibronectin-like molecules of S. apiospermum in the interaction with host lung cells was assessed. Conidia pre-treated with soluble fibronectin showed a significant reduction in adhesion to either epithelial or fibroblast lung cells in a classically dose-dependent manner. Similarly, the pre-treatment of the lung cells with anti-fibronectin antibodies considerably diminished the adhesion. Collectively, the results demonstrated the presence of fibronectin-binding molecules in S. apiospermum cells and their role in adhesive events.

Abstract
Lomentospora prolificans is an opportunistic pathogen that can cause invasive lomentosporiosis in immunocompromised patients. Patients with hematological malignancies and those who have undergone stem cell or solid organ transplantations are in the highest risk group. In addition to the limitations and delays in diagnostic possibilities, L. prolificans has a high mortality due to its resistance to all available antifungal drugs. In a patient diagnosed with aplastic anemia, we described the first case of L. prolificans in Türkiye. L. prolificans was identified in the blood culture, and despite the initiation of antifungal treatments, the fungemia resulted in mortality on the 7th day of intensive care hospitalization. This case highlights the importance of early recognition and prompt initiation of appropriate antifungal therapy to improve the outcome of patients with rare mold infections.

Abstract
BACKGROUND Scedosporiasis is an emerging mycosis that has gained importance in recent years due to its worldwide prevalence. It is caused by species of the Scedosporium apiospermum complex. These species can cause opportunistic infections in immunocompromised patients and, occasionally, in immunocompetent patients as well. The high intrinsic antifungal resistance make these infections difficult to manage. AIMS The objective of this study was to interpret the mycological findings in a transplant patient, together with the images obtained in the radiological studies, in order to provide an early and effective antifungal therapy. METHODS The mycological analysis of samples taken from a heart transplant patient with radiological images suggesting a fungal infection was performed. Computed tomography scan of the head and thorax showed space-occupying lesions in both the frontal lobe and cerebellum, and multiple pulmonary nodules. The nodules were punctured and the samples obtained were analyzed according to the procedures for mycological analysis. The identity of the isolates was confirmed by nucleotide sequencing. Eventually, the antifungal susceptibility was studied. RESULTS The fungal isolates obtained, whose identity was confirmed by sequencing, belonged to the species Scedosporium boydii. Injured tissues were surgically removed and a treatment with amphotericin B and voriconazole-minimum inhibitory concentration (MIC) 0.5μg/mL and ≥0.5μg/mL respectively - was administered. CONCLUSIONS Although the patient died due to complications of a Klebsiella pneumoniae sepsis refractory to treatment, the progression of the fungal disease, although slow, was favourable in the early phases of the treatment due to a correct diagnosis and the antifungal susceptibility test carried out. Clinical cases of this nature highlight the need to increase the epidemiological study of these microorganisms, as well as the proper treatment of the diseases caused, in order to achieve early diagnoses that reduce the morbidity and mortality of patients.

Abstract
BACKGROUND Scedosporiosis/lomentosporiosis is a globally emerging and crucial fungal infection. However, clinical data on Scedosporium/Lomentospora infections in Taiwan are scarce. OBJECTIVES This study aimed to explore the clinical characteristics of Scedosporium/Lomentospora-infected patients and evaluate the susceptibility of these isolates to antifungal agents. METHODS The clinical features of Scedosporium/Lomentospora-infected patients at a tertiary teaching hospital in Northern Taiwan between 2014 and 2021 were retrospectively reviewed; isolates from these patients were identified to species level for antifungal susceptibility testing. RESULTS Among 44 patients, 27 (61.4%) had scedosporiosis/lomentosporiosis, whereas 17 (38.6%) were colonised with Scedosporium/Lomentospora species. Scedosporium apiospermum was the main coloniser; scedosporiosis was primarily caused by S. boydii. Trauma history, steroid and immunosuppressant use were the most common risk factors for developing these infections. Among 27 patients with scedosporiosis/lomentosporiosis, one was lost to follow-up and seven (7/26, 26.9%) died. Most patients with S. apiospermum infection have a history of trauma, leading to cutaneous, bone and ocular infections. Pulmonary, sinus and disseminated infections and mortality were frequently reported in patients with S. boydii infection. Voriconazole's minimum inhibitory concentration was low for S. boydii, S. apiospermum and S. aurantiacum. Caspofungin, micafungin and anidulafungin were active against S. boydii and S. apiospermum. A potentially novel Scedosporium species was identified in this study, with distinct clinical manifestations and antifungal susceptibility. CONCLUSIONS At our centre, S. boydii is the main causative species of scedosporiosis; voriconazole could be the first-line treatment in Taiwan. Our study supports the importance of speciation, rather than only categorising these isolates into S. apiospermum species complex.

Abstract
BACKGROUND Fungal infections, other than candidiasis and aspergillosis, are an uncommon entity. Despite this, emerging pathogens are a growing threat. In the following case report, we present the case of an immunocompromised patient suffering from two serious opportunistic infections in the same episode: the first of these, Nocardia multilobar pneumonia; and the second, skin infection by Scedosporium apiospermum. These required prolonged antibacterial and antifungal treatment. CASE PRESENTATION This case is a 71-year-old oncological patient admitted for recurrent pneumonias that was diagnosed for Nocardia pulmonary infection. Nervous system involvement was discarded and cotrimoxazole was started. Haemorrhagic skin ulcers in the lower limbs appeared after two weeks of hospital admission. We collected samples which were positive for Scedosporium apiospermum and we added voriconazole to the treatment. As a local complication, the patient presented a deep bruise that needed debridement. We completed 4 weeks of intravenous treatment with slow improvement and continued with oral treatment until the disappearance of the lesions occurs. CONCLUSIONS Opportunistic infections are a rising entity as the number of immunocompromised patients is growing due to more use of immunosuppressive therapies and transplants. Clinicians must have a high suspicion to diagnose and treat them. A fluid collaboration with Microbiology is necessary as antimicrobial resistance is frequent.

Abstract
In cystic fibrosis (CF) patients, fungal colonization of the respiratory tract is frequently found. Aspergillus fumigatus, Scedosporium genus, and Exophiala dermatitidis are the most commonly isolated moulds from the respiratory tract secretions of CF patients. The aim of this 5-year surveillance study was to identify trends in species distribution and susceptibility patterns of 212 mould strains identified as Aspergillus spp., Scedosporium spp., and Exophiala spp., isolated from sputum of 63 CF patients who received long-term therapy with itraconazole (ITR) and/or voriconazole (VRC). The Aspergillus isolates were identified as members of the sections Fumigati (n = 130), Flavi (n = 22), Terrei (n = 20), Nigri (n = 8), Nidulantes (n = 1), and Usti (n = 1). Among the 16 species of the genus Scedosporium, 9 were S. apiospermum, 3 S. aurantiacum, and 4 S. boydii. Among the 14 Exophiala species, all were molecularly identified as E. dermatitidis. Overall, 94% (15/16) of Scedosporium spp., 50% (7/14) of E. dermatitidis, and 7.7% (14/182) of Aspergillus spp. strains showed high MIC values (≥8 µg/ml) for at least one antifungal. Particularly, 8.9% (19/212) of isolates showed high MIC values for amphotericin B, 11.7% (25/212) for ITR, 4.2% (9/212) for VRC, and 3.3% (7/212) for posaconazole. In some cases, such as some A. fumigatus and E. dermatitidis isolates recovered from the same patient, susceptibility to antifungal azoles decreased over time. We show that the use of azoles for a long time in CF patients causes the selection/isolation of mould strains with higher MIC values.

Abstract
Infections with Scedosporium spp. and Lomentospora prolificans have become a serious threat in clinical settings. The high mortality rates associated with these infections can be correlated with their multidrug resistance. The development of alternative treatment strategies has become crucial. Here, we investigate the in vitro and in vivo activity of luliconazole (LLCZ) against Scedosporium apiospermum (including its teleomorph Pseudallescheria boydii) and Lomentospora prolificans. The LLCZ MICs were determined for a total of 37 isolates (31 L. prolificans isolates, 6 Scedosporium apiospermum/P. boydii strains) according to EUCAST. Furthermore, the LLCZ antifungal activity was tested in vitro, using an XTT [2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide salt] growth kinetics assay and biofilm assays (crystal violet and XTT assay). In addition, a Galleria mellonella infection model was used for in vivo treatment assays. The MIC90 of LLCZ was determined to be 0.25 mg/L for all tested pathogens. Growth was inhibited within 6 to 48 h of the start of incubation. LLCZ inhibited biofilm formation in both preadhesion stages and late-stage adhesion. In vivo, a single dose of LLCZ increased the survival rate of the larvae by 40% and 20% for L. prolificans and Scedosporium spp., respectively. This is the first study demonstrating LLCZ activity against Lomentospora prolificans in vitro and in vivo and the first study showing the antibiofilm effect of LLCZ in Scedosporium spp. IMPORTANCE Lomentospora prolificans and S. apiospermum/P. boydii are opportunistic, multidrug-resistant pathogens causing invasive infections in immunosuppressed patients and sometimes in healthy persons. Lomentospora prolificans is panresistant against the currently available antifungals, and both species are associated with high mortality rates. Thus, the discovery of novel antifungal drugs exhibiting an effect against these resistant fungi is crucial. Our study shows the effect of luliconazole (LLCZ) against L. prolificans and Scedosporium spp. in vitro, as well as in an in vivo infection model. These data reveal the previously unknown inhibitory effect of LLCZ against L. prolificans and its antibiofilm effect in Scedosporium spp. It represents an extension of the literature regarding azole-resistant fungi and could potentially lead to the development of future treatment strategies against these opportunistic fungal pathogens.

Abstract
Little is known about localized osteoarticular Scedosporiosis (LOS). Most data come from case reports and small case series. Here we present an ancillary study of the nationwide French Scedosporiosis Observational Study (SOS), describing 15 consecutive cases of LOS diagnosed between January 2005 and March 2017. Adult patients diagnosed with LOS defined by osteoarticular involvement without distant foci reported in SOS were included. Fifteen LOS were analyzed. Seven patients had underlying disease. Fourteen patients had prior trauma as potential inoculation. Clinical presentation was arthritis (n = 8), osteitis (n = 5), and thoracic wall infection (n = 2). The most common clinical manifestation was pain (n = 9), followed by localized swelling (n = 7), cutaneous fistulization (n = 7), and fever (n = 5). The species involved were Scedosporium apiospermum (n = 8), S. boydii (n = 3), S. dehoogii (n = 1), and Lomentospora prolificans (n = 3). The species distribution was unremarkable except for S. boydii, which was associated with healthcare-related inoculations. Management was based on medical and surgical treatment for 13 patients. Fourteen patients received antifungal treatment for a median duration of 7 months. No patients died during follow-up. LOS exclusively occurred in the context of inoculation or systemic predisposing factors. It has a non-specific clinical presentation and is associated with an overall good clinical outcome, provided there is a prolonged course of antifungal therapy and adequate surgical management.

Abstract
Scedosporium spp. and Lomentospora prolificans are an emerging group of fungi refractory to current antifungal treatments. These species largely affect immunocompromised individuals but can also be lung colonizers in cystic fibrosis patients. Although Scedosporium apiospermum is thought to be the predominant species, the group has been expanded to a species complex. The distribution of species within the S. apiospermum species complex and other closely related species in the United States is largely unknown. Here, we used β-tubulin and ITS sequences to identify 37 Scedosporium isolates to the species level. These Scedosporium isolates as well as 13 L. prolificans isolates were tested against a panel of nine antifungal drugs, including the first in novel class orotimide, olorofim. IMPORTANCE Scedosporium and Lomentospora infections are notoriously hard to treat as these organisms can be resistant to numerous antifungals. The manuscript contributes to our knowledge of the activity of the new antifungal agent olorofim and comparator agents against Lomentospora and against Scedosporium isolates that have been molecularly identified to the species level. The efficacy of olorofim against all species of Scedosporium and Lomentospora was confirmed.

Abstract
A 69-year-old woman presented with a persistent cough and high fever. Thoracic computed tomography revealed atelectasis and high-attenuation mucus. The blood test results showed eosinophils at 18.2%, an absolute eosinophil count of 980 cells/μL, and a total serum immunoglobulin E of 1980IU/mL. Bronchoscopy revealed a mucous plug, which upon photomicrograph examination, showed eosinophils. A culture study of the mucus yielded Scedosporium apiospermum, leading to the suspicion of allergic bronchopulmonary mycosis (ABPM) caused by the fungus. After the bronchoscopic removal of the mucous plug, her symptoms quickly diminished. She was successfully treated without medication, and ABPM has not recurred for 2 years. To our knowledge, ABPM caused by Scedosporium apiospermum is rare, and close follow-up was effective without the administration of systemic steroids or antifungal drugs.

Abstract
The Scedosporium genus is an emerging pathogen with worldwide prevalence and high mortality rates that gives multidrug resistance to antifungals; therefore, pharmacological alternatives must be sought for the treatment of diseases caused by this fungus. In the present project, six new α-aminophosphates were synthesized by the Kabachnik–Fields multicomponent reaction by vortex agitation, and six new monohydrolyzed α-aminophosphonic acids were synthesized by an alkaline hydrolysis reaction. Antifungal activity was evaluated using the agar diffusion method as an initial screening to determine the most active compound compared to voriconazole; then it was evaluated against 23 strains of the genus Scedosporium following the M38-A2 protocol from CLSI (activity range: 648.76–700 µg/mL). Results showed that compound 5f exhibited the highest antifungal activity according to the agar diffusion method (≤1 mg/mL). Cytotoxicity against healthy COS-7 cells was also evaluated by the MTT assay and it was shown that compound 5f exhibits a lower toxicity in comparison to voriconazole at the same concentration (1000 µM). A docking study was conducted afterwards, showing that the possible mechanism of action of the compound is through the inhibition of allosteric 14-α-demethylase. Taking these results as a basis, 5f is presented as a compound with attractive properties for further studies.

Abstract
Scedosporium and Lomentospora infections in humans are generally chronic and stubborn. The use of azoles alone cannot usually inhibit the growth of these fungi. To further explore the combined effect of multiple drugs and potential mechanisms of action, we tested the antifungal effects of tacrolimus (FK506) and everolimus in combination with azoles in vitro and in vivo on 15 clinical strains of Scedosporium/Lomentospora species and detected the level of Rhodamine 6G, ROS activity, and apoptosis. The in vitro results showed that the combinations of tacrolimus with itraconazole, voriconazole, and posaconazole showed synergistic effects on 9 strains (60%), 10 strains (73%), and 7 strains (47%), respectively, and the combinations of everolimus with itraconazole, voriconazole, and posaconazole showed synergistic effects on 8 strains (53%), 8 strains (53%), and 7 strains (47%), respectively. The synergistic effects might correspond to the elevated ROS activity (the tacrolimus + itraconazole group compared to the itraconazole group, (P < 0.05)), early apoptosis (itraconazole (P < 0.05) and voriconazole (P < 0.05) combined with everolimus), and late apoptosis (the tacrolimus + itraconazole group compared to the itraconazole group, (P < 0.01); the tacrolimus + posaconazole group compared to the posaconazole group, (P < 0.05)), but not inhibition of efflux pump activity. Our in vitro results suggested that a combination of tacrolimus or everolimus and azoles have a synergistic effect against Scedosporium/Lomentospora. The synergistic mechanisms of action might be triggering excessive ROS activity and apoptosis. In vivo, the survival rate of G. mellonella (sixth instar larvae) was significantly improved by tacrolimus alone, everolimus alone, azoles alone, and tacrolimus and everolimus combined with azoles separately (P < 0.05 for the tacrolimus group; P < 0.01 for the everolimus group and the itraconazole group; P = 0.0001 for the tacrolimus and posaconazole group; P < 0.0001 for other groups except the everolimus and itraconazole group, everolimus and posaconazole group, and tacrolimus and itraconazole group). From the results, we infer that the combination of tacrolimus or everolimus with azoles has obvious synergistic effect on Scedosporium/Lomentospora, and might enhance the level of apoptosis and necrosis. However, the synergistic effects were not related to the efflux pump. In conclusion, from our in vitro and in vivo study, tacrolimus and everolimus combined with azoles may have a synergistic effect in the treatment against Scedosporium/Lomentospora, improving the drug activity of azoles and promoting a better prognosis for patients.

Abstract
Invasive aspergillosis and scedosporiosis are life-threatening fungal infections with similar clinical manifestations in immunocompromised patients. Contrarily, Scedosporium apiospermum is susceptible to some azole derivative but often resistant to amphotericin B. Histopathological examination alone cannot diagnose these two fungal species. Pathogenesis studies could contribute to explore candidate protein markers for new diagnosis and treatment methods leading to a decrease in mortality. In the present study, proteomics was conducted to identify significantly altered proteins in A549 cells infected with or without Aspergillus fumigatus and S. apiospermum as measured at initial invasion. Protein validation was performed with immunogold labelling alongside immunohistochemical techniques in infected A549 cells and lungs from murine models. Further, cytokine production was measured, using the Bio-Plex-Multiplex immunoassay. The cytoskeletal proteins HSPA9, PA2G4, VAT1, PSMA2, PEX1, PTGES3, KRT1, KRT9, CLIP1 and CLEC20A were mainly changed during A. fumigatus infection, while the immunologically activated proteins WNT7A, GAPDH and ANXA2 were principally altered during S. apiospermum infection. These proteins are involved in fungal internalisation and structural destruction leading to pulmonary disorders. Interleukin (IL)-21, IL-1α, IL-22, IL-2, IL-8, IL-12, IL-17A, interferon-γ and tumour necrosis factor-α were upregulated in both aspergillosis and scedosporiosis, although more predominately in the latter, in accordance with chitin synthase-1 and matrix metalloproteinase levels. Our results demonstrated that during invasion, A. fumigatus primarily altered host cellular integrity, whereas S. apiospermum chiefly induced and extensively modulated host immune responses.

Abstract
Clinical mycology is in continuous development. The appearance of new clinical guidelines has made it possible to improve the approach to opportunistic fungal infections, especially in immunosuppressed patients (oncohematological and/or transplant recipients). At the same time, the development of new diagnostic tools and new antifungals with a greater spectrum of action and fewer side effects have led to faster diagnoses and treatments that are more effective. Along with these advances, there has been a change in the epidemiology of invasive fungal infection (IFI), with the appearance of new patients (e.g., COPD, liver cirrhosis, post-influenza) and new microorganisms (Candida auris, Lomentospora prolificans, mucorales), and resistant fungi (isolates of Aspergillus resistant to azoles) which the clinician must take into account when choosing the treatment of a patient with an IFI. In this paper we will briefly review the advances in recent decades and the emerging problems.

Abstract
OBJECTIVES To evaluate the in vitro activity of olorofim, a new broad-spectrum antifungal with a novel mechanism of action, against a collection of 123 Spanish clinical isolates belonging to five Scedosporium species and Lomentospora prolificans. METHODS The activity of olorofim against Scedosporium apiospermum (n = 30), Scedosporium boydii (n = 30), Scedosporium ellipsoideum (n = 10), Scedosporium aurantiacum (n = 20), Scedosporium dehoogii (n = 3) and Lomentospora prolificans (n = 30) was compared with that of amphotericin B, voriconazole, isavuconazole and micafungin by performing EUCAST and CLSI reference methods for antifungal susceptibility testing. RESULTS Amphotericin B and isavuconazole showed MICs ≥2 mg/L for all the species evaluated and voriconazole was moderately active (GM, MIC50 and MIC90 values ≤2 mg/L) against all of them except L. prolificans. Micafungin was effective against S. apiospermum complex strains, but exhibited elevated MECs for S. dehoogii and S. aurantiacum. Olorofim showed low MICs for all the Scedosporium strains tested (GM values were lower than 0.130 and 0.339 by the EUCAST method and the CLSI method, respectively, for all of the species), including those belonging to the MDR species L. prolificans, for which GM values were 0.115 and 0.225 mg/L by the EUCAST method and the CLSI method, respectively, while the GMs for the rest of the antifungals evaluated were higher than 3.732 mg/L using both methodologies. CONCLUSIONS Olorofim displayed promising in vitro activity against the Scedosporium and L. prolificans strains tested, some of which have reduced susceptibility to the antifungals that are currently in use.

Abstract
BACKGROUND Suppurative arthritis induced by Scedosporium apiospermum (S. apiospermum) or Mycobacterium fortuitum (MF) was rare, and even more so when caused by a mixed infection of the two. In this paper, we report the rare case of suppurative arthritis induced by S. apiospermum and MF. METHODS A 46-year-old patient whose left knee was accidentally injured by a rotary tiller. His left knee joint was clearly swollen although debridement and suturing had been performed twice at a local hospital. Bacterial culture result was MF and S. apiospermum after admission. Definitive therapy (debridement combined with treatment using three antibiotics) was initiated. RESULTS Although the fungus reappeared when he tried to discontinue the drug, after the third debridement combined with treatment using three antibiotics for 8 months, the infection was controlled and did not recur. CONCLUSIONS This demonstrates that early bacteriological examination is essential. Treatment of fungus generally requires a long course. However, course of medication should be related to the patient's specific conditions and the implementation of the operation.

Abstract
Organotin compounds are applied in several industrial reactions and can present antifungal and antibacterial activities. Incorrect handling and storage practices of biodiesel and diesel-biodiesel blends can lead to microbial development, impacting its final quality. Concerning this problem, this work investigated the antimicrobial action of two organotin catalysts used in biodiesel production with four isolated microroorganisms (Bacillus pumilus, Pseudomonas aeruginosa, Pseudallescheria boydii, and Aureobasidium pullulans) and a pool of microorganisms (ASTM E1259 standard practice). Samples of soybean biodiesel with different concentrations of dibutyl tin dilaurate (catalyst 1) and di-n-butyl-oxo-stannane (catalyst 2) were prepared and added of mineral medium. The pool of microorganisms was inoculated and incubated at 30 °C and final biomass was weighted after 14 days. Thereafter, soybean biodiesel with catalyst 2 was used. Fungal biomass was weighted, and plate count was used to assess bacterial growth. Results show that catalysts 1 and 2 presented no inhibitory activity on the pool of microorganisms evaluated. A slight inhibitory activity was observed for B. pumilus and A. pullulans growth, but not for P. boydii, P. aeruginosa, or the pool of microorganisms. All experiment exhibited acidification higher than sterile control. Infrared analysis show less microbiological degradation products in the tin-protected fuel with ASTM inoculum. These results suggest that these tin-based catalysts show no toxic effect on native microbial population and a slight effect on some isolated microbial population in laboratory scale and for the first time shows that these organotin compounds can be employed safely as biodiesel catalyst.

Abstract
Fungal rhinosinusitis (FRS) is inflammation of the paranasal sinus mucosa due to fungal infections, which can be invasive or non-invasive. The occurrence of a sphenoid mucocele with a fungal ball is rare. We report a case of sphenoid sinus mucocele with a fungal ball caused by Scedosporium apiopermum in a 32-year-old female who presented to the Emergency Department with persistent headache not relieved on medications. The radiological images showed a mucocele with clival osteomyelitis. Urgent endoscopic examination and debridement was undertaken which demonstrated a mucocele with fungal ball. Microbiological examination confirmed it to be Scedosporium apiopermum.

Abstract
BACKGROUND Emerging fungi infections, although being not the most frequent, are a cause of major morbidity and mortality in recipients of solid organ transplants. The infections caused by the fungi Scedosporium apiospermum are a paradigmatic example of these. CASE REPORT We present the clinical case of a 55 year-old female kidney transplant recipient that got infected with S. apiospermum through the skin. Intensive antifungal therapy was started, especially considering that the patient had an arteriovenous fistula at the site of infection. The fungus could have kept in the fistula, and a subsequent reinfection took place. The patient required both medical and surgical treatment (removal of the prosthetic material), that led to a complete recovery. CONCLUSIONS S. apiospermum infections carry a high risk of complications, and are a frequent cause of morbidity and mortality in immunosuppressed/transplant patients. Therefore, the adequate knowledge of this type of mycosis, as well as the making of an adequate differential diagnosis, become fundamental for the prevention of the complications arising from them.

Abstract
The purpose of this study was to investigate the potential of defined co-culture of indigenous bacterial consortium and exogenous fungus Scedosporium boydii for biodegradation of crude oil. After 7 days of incubation, residual oil, n-alkanes and aromatic fraction were analyzed. The degradation rate of crude oil was increased from 61.06% to 81.45% by the defined co-culture according to the 3:1 inoculation ratio of bacteria to fungi. The microbial activity was enhanced markedly and the formation of biofilms was accelerated after suitable inoculation of Scedosporium boydii. High throughput analysis showed that bacterial evenness and diversity were increased and the relative abundance of Paraburkholderia tropica was increased observably from 7.67% to 56.13% in the defined co-culture. These results indicated that synergistic degradation of crude oil in the bacteria-fungi consortium may be advantageous for bioremediation of petroleum-contaminated site.

Abstract
BACKGROUND We report a case with bilateral endogenous fungal subretinal abscesses. To our knowledge, this is the first report from Japan in which Scedosporium prolificans (S. prolificans) was cultured from intraocular tissue. CASE A 74-year-old man, receiving chemotherapy for acute myeloid leukemia, complained of visual loss in both eyes. Best-corrected visual acuity was hand motion in the right and 2/200 in the left eye. His right eye showed exophthalmos, inflammation in the anterior chamber and iris neovascularization. Funduscopy revealed no details as there was vitreous opacity in the right eye, and irregular round yellowish-white subretinal lesions involving the macula in the left eye. Blood culture was negative, and C-reactive protein (CRP) and β-D glucan titers were high. An antifungal drug and broad-spectrum antibiotics were initiated. Two days after the initial visit, right visual acuity had deteriorated to light perception. Enucleation of the right eye was performed for diagnosis and treatment. Fungi were cultured from the subretinal lesion, confirming a diagnosis of S. prolificans infection. After systemic administration and intravitreal injections of antifungal agents, the subretinal abscess in the left eye gradually diminished. At present, six months after the first visit, left visual acuity is 20/200. CONCLUSION Although S. prolificans endophthalmitis can be intractable, this case suggests that repeated intravitreal antifungal agent injections can be effective.

Abstract
Four previously unreported chemical entities, boydone A (1), boydone B (2), botryorhodine F (3), and botryorhodine G (4), along with five known compounds, fusidilactone A (5), (R)-(-)-mevalonolactone (6), (R)-(-)-lactic acid (7), ovalicin (8), and botryorhodine C (9), were isolated from the ethyl acetate extracts of the fermented broths of the fungal strain Pseudallescheria boydii NTOU2362. The structures of 1-9 were characterized on the basis of their spectroscopic data analyses. The absolute configurations of 1 and 2 were established by comparison with the literature and the modified Mosher's method. The growth inhibitory activities of 1-9 against the A549 non-small-cell lung cancer cell line were evaluated, and 2 and 8 exhibited moderate to potent bioactivities with GI₅₀ values of 41.3 and 4.1 μM, respectively, in comparison with fluorouracil (GI₅₀ = 3.6 μM).

Abstract
Cerebral mycosis is a significant cause of morbidity among immunocompromised populations. We present here a case of cerebral infection with Scedosporium apiospermum and Phaeoacremonium parasiticum in a 49-year-old renal transplant recipient. Fourteen years after renal transplantation, the patient presented with invasive pulmonary aspergillosis treated with intravenous liposomal amphotericin B. The patient had clinical and radiographic improvement. However, 6 weeks later, the patient presented with cerebral infection. Magnetic resonance imaging revealed multiple rim enhancing brain abscesses. Brain and cerebrospinal fluid cultures ultimately grew Scedosporium apiospermum and Phaeoacremonium parasiticum. The patient was treated with voriconazole for 6 months and had clinical and radiologic improvement. We believe this is the first reported case of co-infection of the brain with scedosporiosis and phaeohyphomycosis in a renal transplant recipient, who had received intravenous liposomal amphotericin B. Voriconazole may represent a new therapeutic option for these simultaneous infections in the brain.

Abstract
Scedosporium apiospermum is a ubiquitous soil fungus with a worldwide distribution. It can cause a wide range of clinical disease, from cutaneous and subcutaneous infections, to pneumonia, brain abscess, and life threatening systemic illness. The diagnosis of cutaneous disease is with biopsy and culture. We discuss the case of an elderly immunocompromised woman who presented with a persistent erythematous plaque on the elbow after minor trauma. A biopsy revealed Scedosporium apiospermum. Treatment usually requires surgical resection in conjunction with antifungal therapy.

Abstract
A 71-year-old man was referred because of fever and productive cough. His chest radiograph showed a large cavitary mass with an intracavitary mycetoma-like lesion in the left middle lung field. We undertook bronchoscopy and CT-guided biopsy, and both bronchial lavage fluid culture and CT-guided biopsy culture revealed Scedosporium apiospermum. On a diagnosis of lung scedosporiosis, he was treated with 200 mg/day voriconazole for 2 months, but his symptoms did not improve. Measurement of the plasma voriconazole level showed low plasma concentration levels (peak level: 2.15 microg/ml, trough level: 0.72 microg/ml). We then increased the voriconazole dosage from 200 mg/day to 400 mg/day. After that, his symptoms and chest radiograph findings improved immediately, accompanied by an elevated plasma voriconazole level (peak level: 5.13 microg/ml, trough level: 3.13 microg/ml). We believe that measurement of plasma voriconazole levels is useful to determine its dosage in lung scedosporiosis.

Abstract
Scedosporium prolificans is an emerging fungus that causes rapid progressive and disseminated infections in immunodepressed patients. We present a case of a 34-year-old woman with chronic myelogenous leukemia who received a bone marrow transplantation and suffered a sudden respiratory failure in +67 day. Chest radiographies showed growing bilateral patchy condensations. Computed Tomography depicted bilateral nodular condensation of alveolar space. S. prolificans was detected from sputum, but the patient died 72 h later. Imaging findings of lung scedosporiosis are nonspecific, but CT may provide a prompter diagnosis and allow to add newer antifungal treatments. This report presents the first imaging report of lung scedosporiosis.

Abstract
Scedosporium apiospermum, the asexual form of Pseudallescheria boydii, is a ubiquitous fungus that represents an unfrequent complication of immune suppression. It accounts for 20% of all non-Aspergillus mold infections in organ transplant recipients. The infection can be localized or disseminated in multiple organs, including lungs, brain, joints, tendons, and skin, and is difficult to treat, due to resistance of S apiospermum to amphotericin B and other antifungal agents. The mortality rate is about 50%. To our knowledge, there are no prospective studies or registries of transplant recipients to guide diagnosis and there are no evidence-based recommendations for the optimal management of this infection. We report a case of S apiospermum infection in a woman with renal transplantation. The first occurrence of infection was a solitary nodule on the forearm, which was surgically excised. Two following relapses were disseminated to the knee, the Achilles tendon, and the skin of the left leg. The infection was successfully treated with voriconazole, but due to the severe iatrogenic immune suppression, a strong reduction in immunosuppressant drugs was needed.

Abstract
Eumycetoma in the cerebellopontine angle region is extremely uncommon with no case being reported as per an extensive review of the literature by the authors. The authors report a case of cerebellopontine angle eumycetoma in a young female managed by subtotal decompression and antifungal treatment. The pre-operative diagnosis of eumycetoma in this location is extremely difficult and the role of histopathology is very important to characterize this uncommon lesion. The prognosis of this bizarre pathology is dismal despite all treatment modalities as compared to the usual tumors of the cerebellopontine angle that generally have a favorable outcome.
