BACKGROUND: Current guidelines recommend echinocandins as first-line therapy for candidemia. However, several non-Candida yeasts are non-susceptible to echinocandins (echinocandin non-susceptible yeast, ENSY), including Cryptococcus, Geotrichum, Malassezia, Pseudozyma, Rhodotorula, Saprochaete, Sporobolomyces, and Trichosporon. In laboratories that are not equipped with rapid diagnostic tools, it often takes several days to identify yeasts, and this may lead to inappropriate presumptive use of echinocandins in patients with ENSY fungemia...

BACKGROUND: Posaconazole (PCZ) is widely used for prophylaxis or treatment of invasive fungal infections (IFIs) in leukemia patients. However, issues with PCZ tolerability can result in treatment interruption. Isavuconazole (ISA) has a similar broad spectrum of activity to PCZ, however real-world data regarding the tolerability of ISA after PCZ toxicity are lacking. OBJECTIVES: To describe the tolerability of ISA after PCZ toxicity in leukemia patients. PATIENTS/METHODS: We retrospectively assessed tolerability of ISA after PCZ toxicity in adult leukemia patients (March 2015 to November 2017)...

A 68-year-old woman was submitted to our hospital because of erythematous and scaly skin lesions. To exclude tinea samples of stratum corneum were collected and used for mycological investigations. In this material no fungal elements were detected microscopically, but inoculation on Sabouraud agar with cycloheximide yielded a presumptive dermatophyte fungus. Subsequent detailed investigations with conventional morphological and physiological methods and a phylogenetic analysis of the combined LSU rRNA gene (D1/D2 domains) and ITS region sequences suggested that the fungus represents a hitherto undescribed species of the genus Arthroderma...

An alarming pan Indian increase in the incidence of superficial dermatophytosis has been noticed over the past 5-6 years. Recent studies have demonstrated emerging predominance of Trichophyton (T.) mentagrophytes as the causative organism in such cases. Interestingly, a distinct Indian genotype of T. mentagrophytes has been identified and recognised with the help of sequencing of the ITS region of the rDNA. There has however led to a basic confusion owing to the newly introduced taxonomy of dermatophytes in 2017...

The discipline of medical mycology has become increasingly relevant in the face of the rising incidence of invasive fungal infections (IFI), which pose diagnostic and therapeutic challenges for contemporary medical practice. While firmly established in developed countries, medical mycology remains obscure in many low and middle-income countries (LMICs). With a teeming vulnerable populace and an incidence rate of 11.8%, Nigeria has one of the highest estimated burdens of invasive fungal infections (IFIs) in the world...

BACKGROUND: Cryptococcus isolates with high MICs to fluconazole are increasingly reported and a potential clinical impact has been advocated. However, there are different methods to evaluate fluconazole MICs and comparative analysis among such techniques and their comprehensive correlation with clinical outcome are not available. METHODS: Over a 13-year period (2000-2013), fluconazole MICs were determined for 62 cryptococcal isolates recovered from 22 patients with cryptococcosis using CLSI M27-A3, EUCAST, E-test and Sensititre YeastOne, simultaneously...

BACKGROUND: Screening for Aspergillus (Asp-AG) and Candida antigen (Ca-AG) with immunoassays is established for stem cell recipients at high risk for invasive fungal infections (IFI). While parenteral nutrition (PN) will be applied in case of complications leading to insufficient alimentation, piperacillin-tazobactam (TZP) is started at the onset of febrile neutropenia. OBJECTIVES: The aim of this study was to investigate drug-laboratory interactions between PN as well as TZP and both immunoassays which could affect the specificity of the assays and lead to false assumption of an IFI...

The current number of fungal infections occurring each year in Turkey is unknown. We estimated the burden of serious human fungal diseases based on the population at risk, existing epidemiological data from 1920 to 2017 and modelling previously described by the LIFE program (http://www.LIFE-worldwide.org). Among the population of Turkey (80.8 million in 2017), approximately 1 785 811 (2.21%) people are estimated to suffer from a serious fungal infection each year. The model used predicts high prevalences of allergic fungal rhinosinusitis episodes (312 994 cases) (392/100 000), of severe asthma with fungal sensitisation (42 989 cases) (53...

Dihydroxyacid dehydratase (DHAD) is a key enzyme in biosynthetic pathway of isoleucine and valine. This pathway is absent in human but exists in various organisms such as fungi. Using RNA-seq analysis in this study, we identified MGL_3741gene which encodes DHAD protein in Malassezia globosa (M. globosa). Furthermore, we found that mentioned gene is homologous to the Ustilago maydis, Saccharomyces cerevisiae, Aspergillus flavus, and Aspergillus fumigatus ILV3P. For understanding the probable role of this gene in pathogenicity of M...

Invasive fungal diseases (IFD) are a primary cause of morbidity and mortality in patients with haematological malignancies. These infections are mostly life-threatening and an early diagnosis and initiation of appropriate antifungal therapy are essential for the clinical outcome. Most commonly, Aspergillus and Candida species are involved. However, other Non-Aspergillus moulds are increasingly identified in case of documented IFD. For definite diagnosis of IFD, a combination of diagnostic tools have to be applied, including conventional mycological culture and non-conventional microbiological tests such as antibody/antigen and molecular tests, as well as histopathology and radiology...

Candida auris is an emerging multidrug resistant pathogenic fungus that causes candidaemia with high mortality rates and exhibits the ability to persist within the hospital environment. Candida auris is phylogenetically closely related to Candida haemulonii, C. lusitaniae, C. pseudohaemulonii and C. duobushaemulonii and is frequently misidentified by commercial identification methods. In the present study, the GPS™ MONODOSE dtec-qPCR kit (dried single-dose PCR tubes) for the detection of C. auris was validated following the guidelines of the UNE/EN ISO/IEC 17025:2005, the French Standard NF T90-471:2010 and using fast-cycling protocols...

Isolation of representatives of the Cryptococcus neoformans/Cryptococcus gattii species complex can be made using dopamine containing media, such as Niger seed agar and l-DOPA agar. Here, we describe an alternative medium that uses banana flowers. Banana is a dopamine containing fruit and is widely available in tropical and subtropical countries that have high numbers of cryptococcosis patients. This banana blossom-based agar is useful for the enrichment of isolates of the C. neoformans/C. gattii species complex from environmental and clinical materials...
