Opportunistic fungal infections like invasive candidiasis and aspergillozis have high mortality rate particularly in immunosupressive patients. The rate of therapy success with antifungal agents is usually low. Although immunotherapy methods have been developed to increase the host response against antifungals, there has been a need for new antifungal therapeutic agents in the treatment of invasive aspergillozis and other opportunistic fungal infections. Mycoviruses are the viruses that specifically infect fungi...

Invasive fungal infections are an important cause of morbidity and mortality affecting primarily immunocompromised patients. While fungal identification to the species level is critical to providing appropriate therapy, it can be slow, laborious, and often relies on subjective morphologic criteria. The use of MALDI-TOF mass spectrometry has the potential to speed up and improve the accuracy of identification. In this multi-center study, we evaluated the accuracy of the VITEK® MS v3.0 system in identifying 1,601 clinical mold isolates as compared to identification by DNA sequence analysis and supported by morphologic and phenotypic testing...

There currently are 3 topical agents approved by the US Food and Drug Administration (FDA) to treat onychomycosis: tavaborole, efinaconazole, and ciclopirox. The phase 3 clinical trial designs for these treatments and their notable differences make it difficult for clinicians to interpret the data into clinical practice. For example, the primary end point predominantly used to assess efficacy in all the trials is complete cure, defined as no involvement of the nail plus mycologic cure; also, a notable number of patients fail to achieve a complete cure despite clear improvement in the nail...

INTRODUCTION: Fungal interdigital tinea pedis (ITP) is a common pathology mainly due to dermatophytes and yeasts. Fusarium sp. is rarely incriminated in the genesis of intertrigo. In Dakar, a recent study conducted in 2016 on fungal ITP showed that Fusarium were more involved in the etiology of ITP than dermatophytes, coming just after yeasts dominated by Candida. Following this, we wanted to draw attention to the increasing incidence of ITP resulting from Fusarium spp., in Dakar, Senegal, and to analyze the epidemiological and mycological particularities of these ITP due to Fusarium spp...

Chronic pulmonary aspergillosis (CPA) is a severe fungal infection with a high morbidity and mortality, and is usually seen in immunocompetent patients with respiratory disorders. Clinical presentation is nonspecific and often overlaps with the symptoms and the radiological pattern caused by the underlying disease. Clinical management of CPA is further hampered by limited information about the epidemiology, disease dynamics, sensitivity and specificity of different mycological tests, mechanisms of antifungal resistance, efficient treatment and management strategies...

The classification of microorganisms by high-dimensional phenotyping methods such as FTIR spectroscopy is often a complicated process due to the complexity of microbial phylogenetic taxonomy. A hierarchical structure developed for such data can often facilitate the classification analysis. The hierarchical tree structure can either be imposed to a given set of phenotypic data by integrating the phylogenetic taxonomic structure or set up by revealing the inherent clusters in the phenotypic data. In this study, we wanted to compare different approaches to hierarchical classification of microorganisms based on high-dimensional phenotypic data...

Recent years have seen important advances in the diagnosis of invasive pulmonary aspergillosis (IPA), complemented by the introduction of new therapies. Despite this, IPA remains a major cause of infection-related mortality in patients with hematological diseases. There are two main reasons for this. First, diagnosis of IPA remains a challenge, since risk factors and the clinical, radiological and mycological presentations vary not only by fungal disease stage, but also by patient group (e.g. neutropenic versus non-neutropenic patients)...

Actinomucor elegans is a fungus belonging to mucormycetes and is still probably underdiagnosed due to misidentification. Based on a recent first case of Actinomucor elegans sinusitis in Europe, in an immunocompromised patient under voriconazole treatment, this paper aims to summarize knowledge about A. elegans mucormycoses. Even if the diagnosis of mucormycosis was made using traditional mycology techniques, precise identification of the fungus could only be achieved using molecular tools. In this observation, the galactomannan dosage was positive until the introduction of treatment and surgical debridement...

Candida spp. vertebral osteomyelitis is rare. Clinical presentation is unspecific. Diagnosis requires mycological culture of a biopsy specimen. Therapeutic management is based on prolonged course of azole or liposomal amphotericin B. We report the case of Candida tropicalis vertebral osteomyelitis with epidural involvement in a 27 years-old male patient, followed for S-β-thalassemia and with a history of candidemia. The fungus was isolated from a needle biopsy of the vertebral disk. The outcome was favorable under antifungal treatment by amphotericin B and voriconazole...

Deep trichophytosis is relatively uncommon. The infection of the bearded area is also known as sycosis barbae or tinea barbae and can be caused by various fungal species, most often zoophilic fungi. We report on an 80-year-old male patient with severe sycosis barbae who had no animal contact and was treated with systemic antibiosis without improvement. Microbial and mycological investigations using swabs from oozing lesions revealed Staphylococcus hemolyticus and Candida parapsilosis. Histology demonstrated fungal elements in hair follicles...

The Penicillium genera, encompassing about 225 different species of fungi, are naturally present in the environment. These genera are poorly linked to human disease, except for Penicillium marneffei causing septicemia in immunocompromised hosts. Thus, Penicillium species recovered from respiratory tract samples are often considered as inhaled contaminants in the clinical laboratory. However, we report here a case of fungal maxillary sinusitis due to Penicillium roqueforti diagnosed in a 40-year-old female, a teacher, complaining of moderate pain for months in the maxillary sinus and chronic posterior rhinorrhea...

The guideline recommendations, albeit founded on thorough reviews of clinically relevant literature data, are often not immediately adaptable to everyday life. Considering the marked heterogeneity of superficial mycoses, each of them requires specific management in a real life context; in all cases diagnostic confirmation is required with microscopic and culture examination. In tinea capitis oral therapy is necessary (minimum six weeks) and should be continued until clinical and, above all, mycological healing...

Toenail onychomycosis is a chronic fungal infection that often requires prolonged treatment in order to effectively manage pathogenic organisms and obtain a clear nail. Traditionally, certain clinical features of onychomycosis, including the presence of substantial lateral disease, focal fungal masses, yellow/brown streaks, and extensive nail involvement (ie, >50%), indicate a poor treatment prognosis and have proven difficult-to-treat with oral or traditional topical therapies. Owing to the novel features of topical tavaborole, we sought to understand the potential utility of tavaborole in difficult-to-treat onychomycosis...

Tools to diagnose fungal infection are microscopic examination, antigen or antibody-based detection tests, molecular diagnostics, and culture, with culture being the "gold standard" for species-level identification. Although these methods are commonly used in concert and yield concordant results, in some cases tissue is not available for culture, and/or different methodologies yield discrepant results. These discrepancies may be clinically significant, causing confusion and inappropriate or delayed initiation of antifungals...
