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 Phylum Microsporidia01:28

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...

Newer diagnostic markers are crucial for early detection of invasive fungal infections (IFIs). These non-culture based assays improve diagnosis and patient outcomes when timely treatment is critical.

Area of Science:

  • Mycology
  • Infectious Diseases
  • Clinical Diagnostics

Background:

  • Invasive fungal infections (IFIs) have poor patient outcomes due to delayed diagnosis and treatment.
  • Current diagnostic methods like histopathology and cultures are often slow, insensitive, or non-specific.

Observation:

  • Newer non-culture based diagnostic assays are emerging for IFIs.
  • These include antigen/antibody assays (mannan, antimannan antibodies), fungal metabolites (d-arabinitol), and fungal cell wall components (galactomannan, β-glucan).
  • Molecular methods like PCR are also under development but require standardization.

Findings:

  • Surrogate markers offer improved sensitivity and specificity for earlier IFI diagnosis.
  • These markers can potentially provide prognostic information and aid therapeutic monitoring.

  • Combining markers may further enhance diagnostic accuracy.

    • Implications:

    • Earlier diagnosis and treatment of IFIs can significantly improve patient outcomes.
    • Accessible and standardized surrogate assays are needed for widespread clinical implementation.
    • Advancements in diagnostics are vital for managing challenging fungal infections effectively.
