Species of Scedosporium and Fusarium are considered emerging opportunistic pathogens, causing invasive fungal diseases in humans that are known as scedosporiosis and fusariosis, respectively. These mold infections typically affect patients with immune impairment; however, cases have been reported in otherwise healthy individuals. Clinical manifestations vary considerably, ranging from isolated superficial infection to deep-seated invasive infection—affecting multiple organs—which is often lethal...

Members of the Fusarium solani species complex (FSSC) are the most frequently isolated fusaria from soil. Moreover, this complex solely affects more than 100 plant genera, and is also one of the major opportunistic human pathogenic filamentous fungi, being responsible for approximately two-third of fusariosis cases. Mycotic keratitis due to Fusarium species is among the leading causes of visual impairment and blindness in South India, but its management is still challenging due to the poor susceptibility of the isolates to conventional antifungal drugs...

Superficial mycoses are commonly reported in captive pinnipeds, usually maintained in wet and warm environments, favorable to fungal growth. Most superficial mycoses in pinnipeds have been described as difficult to treat; however, the majority of the reports come from past decades. Cutaneous lesions associated with opportunistic Fusarium sp. infections have been previously recognized in this taxon. We described the clinical signs, associated lesions and diagnosis (thermography, imprint cytology, histopathology, culture, electron microscopy, PCR) of a fusariosis case by Fusarium sp...

Fusarium is an emerging human opportunistic pathogen of growing importance, especially among immunosuppressed haematology patients due to an increased incidence of disseminated infections over the past two decades. This trend is expected only to continue due to the advances in medical and surgical technologies that will prolong the lives of the severely ill, making these patients susceptible to rare opportunistic infections. Production of mycotoxins, enzymes such as proteases, angio-invasive property and an intrinsically resistant nature, makes this genus very difficult to treat...

From 2006 to 2013, an increasing incidence of fusariosis was observed in the hematologic patients of our University Hospital. We suspected of an environmental source, and the indoor hospital air was investigated as a potential source of the fungemia. Air samplings were performed in the hematology and bone marrow transplant (BMT) wards using an air sampler with pre-defined air volumes. To study the molecular relationship among environmental and clinical isolates, 18 Fusarium spp. recovered from blood cultures were included in the study...

The genus Fusarium is largely represented in fungal infections, not only mostly in plants but also in humans. Fungi belonging to the Fusarium solani species complex (FSSC) are those that are most frequently isolated in invasive fusariosis and present elevated minimum inhibitory concentrations for the main antifungal drugs used in medicine. This study is the first to investigate the resistance mechanism in FSSC by monitoring CYP51A expression in the presence of azole antifungals. After exposure to voriconazole, an overinduction of CYP51A was observed irrespective of the concentration of antifungal used and the generation studied...

BACKGROUND: Fusariosis is an opportunistic fungal infection that affects mostly leukemic and hematopoietic stem cell transplant patients. Locally invasive and disseminated infection may occur. Treatment is challenging, and besides evaluation of immune status, one also needs to take into account organ involvement to predict the duration and prognosis. OBJECTIVE: The aim of this study was to present the findings and clinical follow-up from a series of cases of Fusarium spp...

We would like to report a case of invasive Fusariosis involving the native mitral valve and complicated by septic thromboembolism. The patient was a known case of end-stage renal disease on maintenance haemodialysis and did not have any of the known risk factors for invasive Fusariosis like neutropaenia, severe T cell immunodeficiency, postsolid organ transplant recipients, posthaematopoietic stem cell transplant recipients and patients who received cytotoxic and/or high-dose corticosteroid therapy.

Infections due to Fusarium species are collectively referred to as fusariosis. Fusarium oxysporum has been reported to cause keratitis, onychomycosis, skin infections, catheter associated fungemia and has not been described as a cause of urinary tract infection. Here, we present the first case of fusariosis with urinary tract involvement in a 67 year old male, with chronic kidney disease and type 2 diabetes mellitus. This case illustrates the ever increasing spectrum of rare but offending pathogenic fungi. Early diagnosis of infection with a specific pathogen may lead to changes in antifungal therapy and may be critical for an improved outcome...

Fusarium species have emerged as responsible for a broad spectrum of infections, including superficial, locally invasive and disseminated ones, especially in the hospital environment. Since there are few reports of invasive and disseminated fusariosis in children, the aim of this study was to report four cases of nosocomial infection caused by this microorganism in children with cancer hospitalized in a public children's hospital located in Brazil. Two of these patients were female and two were male. All patients presented febrile neutropenia, while three patients had acute lymphocytic leukemia and one patient had Wilms' tumor as underlying disease...

Invasive fusariosis has a high mortality and is predominantly observed in patients with leukemia. We report the first case of a novel species of Fusarium, Fusarium riograndense sp. nov, isolated from a lesion in the nasal cavity lesion of a patient with acute lymphoblastic leukemia. The etiological agent was identified by Multilocus Sequencing Typing (MLST), including RPB2, TEF-1α, and ITS-LSU sequences, the gold standard technique to identify new species of Fusarium. MLST and phenotypic data strongly supported its inclusion in the F...

Invasive fusariosis in solid organ transplant is uncommon and usually presents as localized infection with favorable outcomes compared to hematologic malignancies or bone marrow transplants. We report the first case of Fusarium osteomyelitis in a patient following multi-visceral transplant and review Fusarium in organ transplant recipients and Fusarium bone and joint infections. Our case underscores the importance of early recognition and multidisciplinary approach to treatment and highlights potential failure to eradicate with amphotericin B monotherapy...

Disseminated fusariosis is a fatal infection in immunocompromised hosts. However, the optimal antifungal treatment for disseminated fusariosis has not yet been established. We report a case of disseminated fusariosis after chemotherapy for acute lymphoblastic leukemia, presenting with multiple skin, lung, and kidney lesions and cerebrospinal fluid invasion. The combination therapy of liposomal amphotericin B and caspofungin resolved disseminated fusariosis successfully.

Disseminated fusariosis (DF) is a rare life threatening fungal infection in immunocompromised hosts. We herein report a case of a fatal DF mimicking varicella zoster virus (VZV) infection that was emerged from a localized genital infection during cord blood transplantation (CBT) in a patient with severe aplastic anemia (SAA). The patient developed an ulcer following small painful vesicles mimics herpes simplex virus infection (HSV) on the glans penis before CBT, but a Fusarium species was identified. Despite administration of voriconazole, liposomal amphotericin B and granulocyte transfusion, the lesion was extended to extensive skin looked like VZV infection and the patients died after CBT...

The resistance among various opportunistic Fusarium species to different antifungal agents has emerged as a cause of public health problems worldwide. Considering the significance of multi-drug resistant (MDR), this paper emphasizes the problems associated with MDR and the need to understand its clinical significance to combat microbial infections. The search platform PubMed/MEDLINE and a review of 32 cases revealed a common multidrug-resistant profile exists, and clinically relevant members of Fusarium are intrinsically resistant to most currently used antifungals...

Fusarium species are known to cause disseminated cutaneous lesions in immunocompromised patients. Some cases of fusariosis are reported in patients infected with the human immunodeficiency virus. There are two reports in such patients with systemic comorbidities like lymphoma, neutropenia and infective port-a-catheter. Another reported patient had systemic fusariosis, without skin involvement. Diagnosis and treatment of cutaneous fusariosis is difficult and resistance to antifungals is a problem. Our patient was at an advanced human immunodeficiency virus infection stage with disseminated cutaneous fusariosis, without any systemic involvement, who responded completely to oral itraconazole...

Endogenous fungal endophthalmitis (EFE) caused by disseminated fusariosis is a rare condition that generally has a poor outcome, even with intensive therapy. Here, we describe a case in which this type of EFE was diagnosed with vitreous sampling and was successfully treated with 25-gauge vitrectomy and antifungals, including liposomal amphotericin B and voriconazole. A 16-year-old male patient undergoing treatment for acute myeloid leukemia complained of eye pain and blurred vision in his right eye. Treatment was initiated for a vitreous opacity, possibly associated with herpetic retinitis, but the patient worsened and he was referred to us...

Fusarium spp., common soil moulds, are emerging fungal pathogens in immunocompromised subjects. We report the first case of Fusarium solani peritonitis in a patient with liver cirrhosis. Because of the high morbidity and mortality associated with fusariosis, an aggressive approach to treatment as well as identification of the species and drug susceptibilities is warranted.
