Genomic Characterization and Virulence Potential of Two Fusarium oxysporum Isolates Cultured from the International Space Station. mSystems 2019; 4:e00345-18. [PMID: 30944876 PMCID: PMC6426649 DOI: 10.1128/msystems.00345-18] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2019] [Accepted: 02/21/2019] [Indexed: 12/31/2022] Open
Abstract
Two isolates of Fusarium oxysporum, ISS-F3 and ISS-F4, were cultured from the dining table on the International Space Station (ISS). Genomic analyses using EF-1α sequences, presence/absence of effector proteins, k-mer comparisons, and single nucleotide polymorphisms indicate that these two strains are genomically different from 65 known sequenced strains. Functional analysis revealed that ISS-F3/F4 had higher relative abundances of polyketide synthase domains than a non-plant-pathogenic soil isolate, used for biocontrol properties (Fo47), and a clinical isolate (FOSC-3a). Putative secondary metabolite analysis indicates that ISS-F3/F4 may produce yet-unreported polyketides and nonribosomal peptides. While genomic analysis showed that these ISS strains are unlikely to be plant pathogens, a virulence assay using an immunocompromised Caenorhabditis elegans model of fusariosis revealed that they were virulent and may represent opportunistic pathogens in animals, including humans. However, its effects on the health of immunocompromised humans warrant further study. IMPORTANCE This is the first study to isolate and characterize F. oxysporum isolates from a built environment, as well as one that has been exposed to space. The characterization and analysis of these two genomes may have important implications for the medical, agricultural, and food industries as well as for the health of the crew who coinhabit the ISS with these strains.

Abstract
Molds are quite more often suspected as pathogens by the public than by the medical care community. Molds may, however, cause serious medical problems, and mold infections can develop incognito. Among the mycoses caused by opportunistic molds, alternariosis and fusariosis together with aspergillosis are of particular importance. They are more common than other groups with pathological characteristics. The aim of our presentation is to demonstrate the important role of common molds as causative agents in skin and ear infections. The clinical picture, etiology and pathogenesis, diagnosis and treatment, and course and prognosis of cutaneous infections will be given. The spectrum of clinical symptoms ranges from eczemalike lesions to chronic erythematous, verrucous lesions of the skin or multiple acute infiltrations of the dermis, occasionally forming abscesses. The mycologic direct preparation of the specimens, particularly with optical brighteners, and a histological examination of a skin biopsy are strongly recommended. The outbreak of cutaneous infections is triggered by weakened host defense mechanisms. A review of the literature regarding immunosuppressed and immunocompetent patients will be given.

Abstract
Infections by Fusarium species frequently involve the skin, either as the primary or the metastatic site. To better understand the pathophysiology of these infections, 43 new patients with fusariosis were evaluated, and the literature was reviewed. A total of 259 patients (232 immunocompromised and 27 immunocompetent) were identified. Skin involvement was present in 70% of patients, particularly in immunocompromised patients (72% vs. 52%; P=.03). In immunocompetent patients, cutaneous infections were characterized by preceding skin breakdown, localized involvement, slow pace of progression, and good response to therapy. In contrast, skin involvement in immunocompromised patients was only occasionally preceded by skin breakdown and typically was presented as rapidly progressive disseminated lesions at various stages of evolution. Metastatic skin lesions were associated with fungemia, neutropenia, and death. Skin was the single source of diagnosis for the majority of immunocompromised and immunocompetent patients. Recommendations for the prevention of fatal fusariosis originating from skin are presented.

Abstract
Doses of 10 to 100 mg of the azole antifungal agent SCH 5692/kg of body weight/day were studied in immunocompetent mice as therapy for systemic infection by Fusarium solani. Treatment was begun 1 h after intravenous infection and continued daily for 4 or 13 doses. Prolongation of survival and organ clearance were dependent on both the dose and the duration of SCH 56592 therapy, with the best results seen at 50 and 100 mg/kg/day. The results at the highest doses of SCH 56592 used (50 or 100 mg/kg/day) were comparable to those obtained with amphotericin B at 1 mg/kg/day. SCH 56592 has potential for therapy of systemic infections caused by F. solani.

Abstract
AbstractDespite increasing reports of life-threatening Fusarium infections, little is known about its pathogenesis and management. To evaluate the epidemiology, clinicopathologic features, and outcome of invasive fusariosis in patients with hematologic cancer, we conducted a retrospective study of invasive fusarial infections in patients with hematologic malignancy treated at a referral cancer center over a 10-year period (1986 to 1995), as well as a literature review. Forty patients with disseminated and three patients with invasive lung infection were included in the analysis. All patients were immunocompromised. The infection occurred in three patients postengraftment following bone marrow transplantation. All patients were diagnosed antemortem. Thirteen patients responded to therapy, but the infection relapsed in two of them. Response was associated with granulocyte transfusions, amphotericin B lipid formulations (four patients each), and an investigational triazole (two patients). Resolution of infection was only seen in patients who ultimately recovered from myelosuppression. Portal of entry was the skin (33%), the sinopulmonary tree (30%), and unknown (37%). Fusarium causes serious morbidity and mortality, and may mimic aspergillosis. The infection seems to respond to newer therapeutic approaches, but only in patients with ultimate recovery from myelosuppression, and it may relapse if neutropenia recurs.

Abstract
Fusarium species are common hyaline soil saprophytes and plant pathogens which have frequently been reported as etiologic agents of opportunistic infections in humans. These infections have usually been limited to superficial mycoses, but recently the number of infections of deep tissues and disseminated infections has greatly increased, especially in patients with an underlying immunosuppressive condition. The characteristic signs of these infections are disseminated skin nodules, fungemia and multiorgan involvement. Frequently, myalgia is also present. Skin involvement occurred in over 80% of cases of disseminated infections. These lesions are significant because they are readily accessible for biopsy and culture, thus permitting an early diagnosis. The therapy and outcome are dependent on the degree of invasion of the organisms and the status of the host. Identification of the pathogen to genus level is not difficult, but identification to species level requires a greater degree of expertise. Up to now, 15 species of Fusarium have been reported to cause infections in humans and animals. Few patients with disseminated fusarial infections have survived, even after receiving an adequate dosage of amphotericin B, the only antifungal agent that has some effect against these fungi. In vitro susceptibility to amphotericin B is a poor predictor of the clinical outcome of invasive fungal infections. Recovery of the phagocytic mechanisms in the form of rising neutrophil counts appears to be mandatory for clinical resolution. The resolution of neutropenia may be aided by the use of exogenous growth factors. Outside the USA, the majority of cases of disseminated fusarial infection have been reported from Mediterranean or tropical countries.

Abstract
Exophiala jeanselmei and Mycobacterium chelonae were isolated from cutaneous nodules in a 73-year-old man with mycetoma of the right lower leg. Further evaluation revealed CD4+ lymphocytopenia without evidence of HIV infection. Antibodies to HIV 1/2, p24 antigen and HIV 1/2 (PCR) and reverse transcriptase activity were not detectable. The patient was not a member of any HIV risk group. He had not previously undergone therapy or suffered from immunodeficiency. This case clearly demonstrates that infections with opportunistic moulds and/or atypical mycobacteria should be taken into consideration not only in patients with classical immundeficiency diseases but also in apparently healthy patients because infection with these agents can be the first sign of underlying immunodeficiency.

Abstract
We report a case of a severe Fusarium solani keratitis in a 82-year-old patient with a history of surgical trauma. Antimycotic therapy and keratoplasty led to markedly improved vision. Identification of the fungus was complicated by the fact that the isolate did not produce the typical macroconidia. The second case was a fatal disseminated Fusarium verticillioides infection in a 69-year-old patient during neutropenia after chemotherapy of acute myelogenous leukemia. The patient developed pneumonia, fever, skin lesions, myalgia, and fungaemia. The clinical signs, diagnosis and therapy of localized and disseminated Fusarium infections are outlined and discussed in view of the literature.

Abstract
Five cases are reported of Fusarium infection in patients with aplasia following chemotherapy of leukemia. The clinical signs, diagnosis and course of the infection during treatment are outlined and discussed in conjunction with the characteristics of other cases already reported in the literature. Sixty-three cases of Fusarium infection have been reported in immunocompromised patients, 44 cases since 1985. These included patients with hematological malignancies (58 cases), especially acute leukemia (43 cases). The main sites of infection were the skin (46 cases), blood (28 cases) and lungs (13 cases). The infection was mostly diagnosed by means of skin biopsy but also by means of positive blood cultures. Forty-three strains were identified, 19 of which were Fusarium solani. Amphotericin B treatment was given in 55 cases, often combined with other antifungal agents, leukocyte transfusions or granulocyte-macrophage-colony stimulating factor. The outcome was fatal in 36 of the 63 cases reported, often due to resistance of the strain to antifungal agents, particularly amphotericin B (20 of 33 strains tested). The most important risk factor seems to be profound and prolonged aplasia. Deep mycoses due to Fusarium species thus pose an important problem and are occurring in increasing numbers in immunocompromised patients. Treatment of these infections is difficult and the prognosis is poor.
