BACKGROUND: Fungal infections of the central nervous system (FIs-CNS) have become significantly more common over the past 2 decades. Invasion of the CNS largely depends on the immune status of the host and the virulence of the fungal strain. Infections with fungi cause a significant morbidity in immunocompromised hosts, and the involvement of the CNS may lead to fatal consequences. METHODS: One hundred and thirty-five articles on fungal neuroinfection in PubMed, Google Scholar, and Cochrane databases were selected for review using the following search words: "fungi and CNS mycoses", CNS fungal infections", "fungal brain infections", " fungal cerebritis", fungal meningitis", "diagnostics of fungal infections", and "treatment of CNS fungal infections"...

Arbuscular mycorrhizal and ectomycorrhizal symbioses are among the most important drivers of terrestrial ecosystem dynamics. Historically, the two types of symbioses have been investigated separately because arbuscular mycorrhizal and ectomycorrhizal plant species are considered to host discrete sets of fungal symbionts (i.e., arbuscular mycorrhizal and ectomycorrhizal fungi, respectively). Nonetheless, recent studies based on high-throughput DNA sequencing technologies have suggested that diverse non-mycorrhizal fungi (e...

Cerebral phaeohyphomycosis is an infection caused by a number of dematiaceous fungi, characterised by the presence of melanised hyphae in the invaded tissue. Cladophialophora bantiana is the most common species affecting the humans, which has a predilection for causing the central nervous system infections resulting in high mortality. We hereby report a success story of two cases of brain abscess caused by C. bantiana who were treated with surgical source reduction and voriconazole therapy.

Chromoblastomycosis is a chronic cutaneous fungal infection commonly caused by Fonsacea and Cladophialophora spp . Dermoscopy is a non-invasive, real-time diagnostic tool for rapid bedside diagnosis of various inflammatory and non-inflammatory disorders and can be an excellent modality for evaluation of cutaneous mycosis, for which it shows characteristic brown dots, crust, scales and yellow orange structures.

Soil fungi associated with plant roots, notably ectomycorrhizal (EcM) fungi, are central in above- and below-ground interactions in Mediterranean forests. They are a key component in soil nutrient cycling and plant productivity. Yet, major disturbances of Mediterranean forests, particularly in the Southern Mediterranean basin, are observed due to the greater human pressures and climate changes. These disturbances highly impact forest cover, soil properties and consequently the root-associated fungal communities...

Fonsecaea and Cladophialophora are genera of black yeast-like fungi harboring agents of a mutilating implantation disease in humans, along with strictly environmental species. The current hypothesis suggests that those species reside in somewhat adverse microhabitats, and pathogenic siblings share virulence factors enabling survival in mammal tissue after coincidental inoculation driven by pathogenic adaptation. A comparative genomic analysis of environmental and pathogenic siblings of Fonsecaea and Cladophialophora was undertaken, including de novo assembly of F...

Cladophialophora bantiana brain abscesses are rare, but are frequently and quickly lethal in transplanted patients. We report the case of a 63-year-old man who had undergone lung transplantation for chronic obstructive pulmonary disease and presented with headaches and a neurological deficit. Magnetic resonance imaging revealed multiple brain abscesses. C. bantiana was identified by DNA sequencing performed directly on cerebral tissue obtained by surgical biopsy. After 6 months of antifungal treatment, the brain abscesses were replaced by ischemic sequelae...

Cladophialophora immunda is an ascomycotal species belonging to the group of the black yeasts. These fungi have a thick and melanized cell wall and other physiological adaptations that allows them to cope with several extreme physical and chemical conditions. Member of the group can colonize some of the most extremophilic environments on Earth. Cladophialophora immunda together with a few other species of the order Chaetothyriales show a special association with hydrocarbon polluted environments. The finding that the fungus is able to completely mineralize toluene makes it an interesting candidate for bioremediation purposes...

Zearalenone (ZEN) is a mycotoxin which causes huge economic losses in the food and animal feed industries. The lactonase ZHD101 from Clonostachys rosea, which catalyzes the hydrolytic degradation of ZEN, is the only known ZEN-detoxifying enzyme. Here, a protein homologous to ZHD101, denoted CbZHD, from Cladophialophora batiana was expressed and characterized. Sequence alignment indicates that CbZHD possesses the same catalytic triad and ZEN-interacting residues as found in ZHD101. CbZHD exhibits optimal enzyme activity at 35°C and pH 8, and is sensitive to heat treatment...

Chromoblastomycosis (CBM) is a chronic, progressive, cutaneous and subcutaneous fungal infection following the traumatic implantation of certain dematiaceous fungi. The disease has worldwide prevalence with predominant cases reported from humid tropical and subtropical regions of America, Asia, and Africa. Diagnosis is often delayed or misdirected either due to poor degree of clinical suspicions or clinical simulation of dermatological conditions. The infection is not uncommon in India and several case reports from the sub-Himalayan belt and western and eastern coasts of India have been published; however, very few have reviewed the cases...

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...
