Ringworm is highly contagious and can be transmitted directly from person to person through touch. It can also be transferred indirectly via contaminated objects, making public swimming pools, locker rooms, and contact sports such as wrestling common sources of infection.

Tineas, commonly referred to as ringworm, are cutaneous fungal infections that often produce radially spreading lesions that heal in the center. Despite the common name, ringworm is not caused by an actual worm.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

A Wood's lamp is a diagnostic tool that produces ultraviolet light. When shone on certain skin lesions, such as those caused by ringworm, the light causes the affected area to fluoresce, assisting in clinical diagnosis.

Tineas, or ringworm, typically manifest as itchy, red, circular skin lesions with a raised red edge.

Signs and Symptoms of Tineas

Transmission of Ringworm

Dermatophytes are a group of pathogenic, keratin-requiring ascomycetes from the genera *Trichophyton*, *Microsporum*, and *Epidermophyton*. They are capable of causing cutaneous mycoses, including skin infections such as athlete's foot, jock itch, and ringworm.

Dermatophytes

To diagnose tineas (ringworm), a skin scraping is first examined under a microscope to confirm a fungal infection. If initial treatment fails, culturing the fungus on a growth medium is required for positive identification of the specific fungal species.
