    Abstract

    Insights

    This study identified the common causes of onychomycosis (nail infections) in Turkey, finding Trichophyton rubrum most frequent in toenails and Candida albicans in fingernails.

    Area of Science:

    • Medical Mycology
    • Dermatology
    • Infectious Diseases

    Background:

    • Onychomycosis is a persistent nail infection caused by fungi like dermatophytes, Candida, and molds.
    • Identifying causative agents is crucial for effective treatment strategies.

    Purpose of the Study:

    • To determine the specific fungal pathogens responsible for onychomycosis in patients within a defined region.
    • To provide regional data on the prevalence of different etiologic agents causing nail infections.

    Main Methods:

    • A retrospective analysis of 225 diagnosed onychomycosis cases over 27 months.
    • Inclusion criteria: diagnosis confirmed by fungal culture.
    • Data collected from Bezmialem Vakif University, Istanbul, Turkey.

    Main Results:

    • The study included patients aged 2 to 87 years, with a higher prevalence in females (53.3%).
    • Lateral and distal subungual onychomycosis was the most common clinical presentation (80%).
    • Key identified pathogens: Trichophyton rubrum (34.2%), Trichophyton mentagrophytes (13.3%), Candida albicans (12.4%), and Candida parapsilosis (11.1%).

    Conclusions:

    • Trichophyton rubrum was the predominant etiologic agent in toenail onychomycosis.
    • Candida albicans was the most frequently isolated pathogen in fingernail onychomycosis.

    Fungal Phylum Microsporidia

    Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

    Skin Diseases and Disorders

    Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
    Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

    Fungal Group Zygomycota

    Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
