Insights

Human fungal infections from contact are uncommon but include many dermatophyte and tinea infections. This review covers the epidemiology, diagnosis, and treatment of these anthropophilic fungal diseases.

Area of Science:

  • Mycology
  • Dermatology
  • Infectious Diseases

Background:

  • Fungal infections acquired through human or animal contact are less common but represent a significant portion of dermatophyte infections.
  • Dermatomycoses are among the most frequent integumentary diseases encountered.
  • Sources of fungal infections include tinea, candidal, and other superficial or deep mycoses.

Purpose of the Study:

  • To review the epidemiology, clinical features, diagnosis, and treatment of anthropophilic dermatophyte infections.
  • To focus on infections prevalent in North America.
  • To briefly discuss other human-acquired and zoonotic fungal infections.

Main Methods:

  • Narrative review of existing literature.
  • Synthesis of epidemiological data.
  • Compilation of clinical features, diagnostic methods, and treatment strategies.

Main Results:

  • Anthropophilic dermatophyte infections are a notable category of human-acquired mycoses.
  • Tinea infections are commonly acquired through direct contact.
  • The review provides an overview of diagnosis and treatment options for these conditions.

Conclusions:

  • Understanding the epidemiology and clinical presentation of anthropophilic dermatophyte infections is crucial for effective management.
  • Prompt diagnosis and appropriate treatment are essential to prevent the spread and chronicity of fungal skin infections.
  • Further research into zoonotic and other human-acquired fungal infections can improve public health strategies.

Contact-dependent Signaling01:19

Contact-dependent Signaling

Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

Contact Angle01:13

Contact Angle

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

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...

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...

Fungal Phylum Ascomycota

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

Fungal Phylum Basidiomycota01:26

Fungal Phylum Basidiomycota

Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...
