Multicentre Study of Candida parapsilosis Blood Isolates in Türkiye Highlights an Increasing Rate of Fluconazole Resistance and Emergence of Echinocandin and Multidrug Resistance.

Objectives: Worldwide emergence of clonal outbreaks caused by fluconazole-resistant (FLCR) and the recent emergence of echinocandin- and multidrug-resistant (ECR and MDR) Candida parapsilosis isolates pose serious threats to modern clinics. Conducting large-scale epidemiological studies aimed at determining the genetic composition and antifungal resistance rates is necessary to devise antifungal stewardship and infection control strategies at international, national and local levels. Despite being severely hit by outbreaks due to FLCR C.

A multidimensional assessment of in-host fitness costs of drug resistance in the opportunistic fungal pathogen Candida glabrata.

Drug-resistant microbes typically carry mutations in genes involved in critical cellular functions and may therefore be less fit under drug-free conditions than susceptible strains. Candida glabrata is a prevalent opportunistic yeast pathogen with a high rate of fluconazole resistance (FLZR), echinocandin resistance (ECR), and multidrug resistance (MDR) relative to other Candida. However, the fitness of C.

Phaeohyphomycosis caused by , a plant pathogen worldwide.

Although rare, trans-kingdom infection features an interesting infection biology concept, in which highly versatile pathogenic attributes allow successful infections in evolutionarily highly divergent species. is a phytopathogenic fungus and occasionally causes human infections. Herein, we report a phaeohyphomycosis case caused by .

Echinocandin persistence directly impacts the evolution of resistance and survival of the pathogenic fungus .

Unlabelled: Recent epidemiological studies documented an alarming increase in the prevalence of echinocandin-resistant (ECR) blood isolates. ECR isolates are known to arise from a minor subpopulation of a clonal population, termed echinocandin persisters. Although it is believed that isolates with a higher echinocandin persistence (ECP) are more likely to develop ECR, the implication of ECP needs to be better understood.
