Veronaea botryosa has been identified as a pathogen of cultured white sturgeon Acipenser transmontanus. In 2015, samples from 19 white sturgeon were received for diagnosis, of which 14 cultured positive for V. botryosa. Intraspecific variability among V. botryosa isolates from different clinically affected hosts and geographic regions was investigated using repetitive extragenic palindromic PCR fingerprinting (rep-PCR). The rep-PCR profiles of 16 V. botryosa isolates from a human, sea turtles, and cultured fish were distinct from those of other phaeoid fungi belonging to the genera Cladophialophora and Exophiala...

BACKGROUND: Chromoblastomycosis (CBM) is a chronic fungal disease. In China, the principle etiologic agent was a group of dematiaceous fungi, including Fonsecaea monophora, Fonsecaea nubica, and Cladophialophora carrionii. Although the Fonsecaea species have similar morphology, their pathogenicity is quite different. This study aims to establish a new solution for early identification of Fonsecaea species because of their distinctive potential infection risk. METHODS: Five reference strains and 35 clinical isolates from patients with CBM, preserved in our laboratory, were used in this study...

BACKGROUND: Central nervous system infection with Cladophialophora bantiana (Black Mold) is rare. It carries a high mortality rate, that is more than 70%, despite multimodal therapy. CASE DESCRIPTION: We present a rare case of "black mold" fungal brain abscess that was successfully treated with good patient outcome. The case is unusual because there were two fungal brain abscesses located bilaterally symmetrically in the mesial frontal lobes, and the response to different treatment strategies was well documented by over 25 magnetic resonance imaging (MRI) scans...

The order Chaetothyriales (Pezizomycotina, Ascomycetes) harbours obligatorily melanised fungi and includes numerous etiologic agents of chromoblastomycosis, phaeohyphomycosis and other diseases of vertebrate hosts. Diseases range from mild cutaneous to fatal cerebral or disseminated infections and affect humans and cold-blooded animals globally. In addition, Chaetothyriales comprise species with aquatic, rock-inhabiting, ant-associated, and mycoparasitic life-styles, as well as species that tolerate toxic compounds, suggesting a high degree of versatile extremotolerance...

Melanized or black fungi are a heterogeneous group of fungi causing cutaneous to systemic diseases with high mortality. These fungi are rarely reported as agents of human infections, primarily due to difficulties in their classical identification. In this study, we examined, using molecular methods and matrix-assisted laser desorption ioniazation-time of flight mass spectrometry (MALDI-TOF MS), the diversity of melanized fungi (MF) isolated from patients in 19 medical centers in India. Overall, during a 4-year period, 718 (5...

Cladophialophora bantiana is a phaeoid fungus that only rarely has been isolated from sources other than the human brain. It has a particular tropism for the central nervous system (CNS). We have integrated and updated large-scale data related to several aspects of C. Bantiana and reviewed all the available reports on its cerebral infections, focusing on their geographical distribution, infection routes, immune status of infected individuals, type and location of infections, clinical manifestations and treatment and outcome, briefly looking over the spectrum of other disease entities associated with C...

INTRODUCTION: Invasive fungal disease (IFD) is an important complication after solid organ transplantation (SOT). A marked geographic variation in the epidemiology of IFD after kidney transplantation (KT) has been suggested by the results of previous studies. Nevertheless, data from Latin American centers are scarce. OBJECTIVE: This study sought to describe the epidemiology of IFD at a Brazilian KT center. METHODS: This study was a retrospective single-center cohort study that included patients who underwent KT between 1998 and 2009 and were followed up until July 2015...

Phaeohyphomycosis is a term used to describe infections caused by dematiaceous fungi, i.e. fungi which contain melanin in their cell wall. Cladophialophora bantiana has been implicated to cause brain abscess in immunocompromised patients. Infection caused by Cladophialophora bantiana in an immunocompetent host is relatively rare. Surgical site infection at abdominal subcutaneous tissue caused by Cladophialophora bantiana was noted in this case, which was rarely reported.

Chromoblastomycosis is a chronic infection, caused by pigmented fungi affecting skin and subcutaneous tissues characterized by verrucous nodules or plaques. Fonsecaea pedrosoi and Cladophialophora carrionii are the prevalent agents in the endemic areas. Phoma is an uncommon agent of human infection and involved mainly with phaeohyphomycosis cases. The case of a patient with a history of laceration in foot followed by verrucous aspect and scaly lesions, which had evolved for 27 years is presented. On physical examination disease was clinically compatible with chromoblastomycosis and the microscopic examination of scales showed fumagoid cells...

A collection of 163 strains of black yeast-like fungi from the CBS Fungal Biodiversity Center (Utrecht, The Netherlands), has been screened for the ability to grow on hexadecane, toluene and polychlorinated biphenyl 126 (PCB126) as the sole carbon and energy source. These compounds were chosen as representatives of relevant environmental pollutants. A microtiter plate-based culture assay was set up in order to screen the fungal strains for growth on the selected xenobiotics versus glucose, as a positive control...

Primary central nervous system phaeohyphomycosis is a fatal fungal infection due mainly to the neurotropic melanized fungiCladophialophora bantiana,Rhinocladiella mackenziei, andExophiala dermatitidis.Despite the combination of surgery with antifungal treatment, the prognosis continues to be poor, with mortality rates ranging from 50 to 70%. Therefore, a search for a more-appropriate therapeutic approach is urgently needed. Ourin vitrostudies showed that with the combination of amphotericin B and flucytosine against these species, the median fractional inhibitory concentration (FIC) indices for strains ranged from 0...
