Antifungal drug resistance in dermatophytes was first reported shortly after the turn of the millennium and has today been reported in Trichophyton and occasionally in Microsporum, but not in Epidermophyton species. Although... Read More
During the past decade, a severe outbreak has taken place in India of terbinafine-resistant strains in the Trichophyton mentagrophytes / T. interdigitale complex. In this study, a total of 145 isolates of... Read More
Resistance of dermatophytes against antifungal agents was not perceived as a problem for decades. Therapy failure in onychomycosis or tinea capitis was never related to a reduced in vitro susceptibility of the... Read More
Onychomycosis is frequently recalcitrant to treatment. The issue of terbinafine resistance has been raised by the current epidemic of dermatophytoses in India. Laboratory identification and microdilution susceptibility testing of the causative agent... Read More
The Indian ITS genotype VIII T. mentagrophytes population shows a high amount of different erg1 (ergosterol) mutants encoding for squalene epoxidase, which catalyzes the first step of ergosterol biosynthesis. Implication of point... Read More
Changes in dermatophyte epidemiology in Europe should be continuously monitored and reported, in view of the increased human mobility from and to endemic areas and the increased cohabitation of humans with animal... Read More
Dermatophytosis, tinea, is a common infection and world-wide distributed. It has until recently been considered a mild infection and easy to treat. Unfortunately, an epidemic of atypical widespread recalcitrant and terbinafine resistant... Read More

Session 2: Taxonomy of keratinophilic and dimorphic fungi
Members of the order Onygenales can be found on diverse sources. Before the molecular techniques were introduced in Mycology, identification and classification of the species were based on mainly morphological features. Molecular... Read More
Order Onygenales is unique in the sense that most of its members have affinity towards keratin. This feature of keratin degradation is rarely found in any other order in the whole of... Read More
Emmonsia crescens is known as an environmental pathogen causing adiaspiromycosis in small rodents. As the generic name Emmonsia is no longer available for this species, its taxonomic position is reevaluated. The intraspecific... Read More
Four new Keratinophyton species (Ascomycota: Pezizomycotina, Onygenales), isolated from soil samples originating from Europe (Austria, Italy and Slovakia) are described, illustrated and presented here. The new taxa are well supported by phylogenetic... Read More
Species of the Trichophyton benhamiae complex are predominantly zoophilic pathogens with a worldwide distribution. These pathogens have recently become important due to their epidemic spread in pets and pet owners. Considerable genetic... Read More
A severe outbreak of highly virulent and multi-resistant dermatophytosis is ongoing in India. There is a debate about the correct identification of the etiologic agent: Trichophyton mentagrophytes or T. interdigitale. In order... Read More
Trichophyton interdigitale is one of the most common agents of tinea pedis and onychomycosis in humans. The closely related species T. mentagrophytes is primarily the agent of superficial infections in animals (e.g.... Read More
In recent years many advances have been made in clearing up the phylogenetic relationships within the family Arthrodermataceae. However, certain closely related taxa still contain poorly resolved species boundaries. Here we try... Read More
Microsporum canis is the most common dermatophyte in cats and dogs, with cats considered to be the most important reservoir hosts. M. canis is diffused worldwide and plays an important zoonotic role.... Read More
The Trichophyton rubrum species group consists of prevalent causative agents of human skin, nail and hair infections, including T. rubrum sensu stricto and T. violaceum, as well as other less well established... Read More
Trichophyton erinacei is increasingly reported as a cause of dermatophytosis in wild and pet hedgehogs, their breeders, and owners worldwide. The pathogen was originally described in the European hedgehog (Erinaceus europaeus), occurring... Read More
The aim of the study was to detect potentially pathogenic fungi in skin lesions of wild sables Martes zibellina from Siberia region of Russia. Outbreaks of mass skin lesions in Siberian sables... Read More
Valley fever or coccidioidomycosis is a life-threatening fungal infection caused by inhalation of arthroconidia (airborne particles) of the two closely related species, Coccidioides immitis and C. posadasii, present in soil and dust... Read More
Histoplasmosis is one of the most prevalent fungal infections (500,000 infections estimated per year) and is one of the most common pulmonary diseases in the world. The prevalence of histoplasmosis varies greatly... Read More
Emergomycosis is a systemic fungal disease caused by thermally dimorphic fungus Emergomyces spp., so named because of its recent global emergence. It was formerly classified under genus Emmonsia but a taxonomic revision... Read More
Exotic reptiles have taken in a niche of popular companion animals in recent decades. However, the importance of fungal infections in reptiles is still underestimated in many cases. Mycoses in reptiles can... Read More
The upraising number of European hedgehogs (Erinaceus europaeus) admitted every year to wildlife rehabilitation centres in Western Europe might be a source of concern to animal and public health since transmissible diseases,... Read More
For about 10 years, a new variant of the pathogen Trichophyton (T.) benhamiae has been appearing in Germany, characterised by a previously unobserved culture phenotype with a strong yellow reverse. A few... Read More
Tinea capitis (TC) is a superficial infection of the scalp caused by dermatophyte fungi which affects mainly prepubescent children. This last decade, a huge increase of African anthropophilic strains causing tinea capitis,... Read More
A large-scale molecular epidemiology project has been conducted by a collaborative network of 8 institutions in the Czech Republic. Isolates and associated data obtained between 2012 and 2019 were analysed. Huge collection... Read More
The changes in the epidemiology of dermatophyte fungi and related infections (Dermatophytosis or tinea) in Iran are presented here. A comprehensive literature search was carried out. We found that mycological and clinical... Read More
Several countries reported differences in dermatophytes epidemiology that have been associated with migration from endemic areas. We analysed notified dermatophytoses/tinea infections (N=52 600) in Slovenia 2006–2019. Tinea most frequently affected persons aged... Read More
Part 1 Iraq – Objectives: From Iraq, few data on the occurrence of dermatophytes are available. A study on prevalence of dermatophytes in Baghdad, Iraq, was done. Patients and methods: From April... Read More
The first purpose of this study was to compare the efficiency of mould/dermatophytes identification by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) using a new medium called Id-Fungi... Read More
Moulds and dermatophytes keep appearing more frequently in the microbiological routine. The diagnosis of mould infections is often based on morphological criteria. These may encounter time-consuming sporulation as a prerequisite for identification.... Read More
Onychomycosis is the most common nail disorder. Current treatment of this infection does not achieve ideal results in the efficacy and has the potential for adverse effects. The aim of this study... Read More
Histoplasma and Paracoccidiodes are both thermodimorphic fungi and endemic in some geographic areas. Paracoccidiomycosis is a systemic fungal disease occurring in Latin America and it is more prevalent in South America. Histoplasma... Read More

White and yellow strains of Trichophyton benhamiae are well known pathogens of pet animals with frequent transmission to humans. Based on the recent data, white phenotype strains form three subgroups which are... Read More
Coccidioides immitis and C. posadasii are soil dwelling dimorphic fungi found in North and South America. Inhalation of environmentally produced conidia results in infection. Coccidioides spp. make specialized parasitic spherules, which contain... Read More
Microbial pathogens rely on exploiting host nutrients to proliferate during infection. Intracellular pathogens, particularly those exclusively living in the phagosome such as the primary pathogen Histoplasma capsulatum, must be able to assimilate... Read More
