With a skin lesion, the area of infection should be washed with a mild disinfectant and the hair should be trimmed to a length of 0.5 cm.
The sample should be collected from the active borders of several suspect sites with hemostats by grasping the hair shafts close to the skin and rolling the hairs from the follicles..
How is ringworm diagnosed? Your healthcare provider might suspect you have ringworm by looking at the affected skin and asking questions about your symptoms.
Your healthcare provider will generally take a small skin scraping or nail sample to examine under a microscope or send to a laboratory for further testing..

He or she may also take a small skin scraping to be examined under a microscope or sent to a laboratory for a fungal culture..
Ringworm often causes a ring-shaped rash that is itchy, scaly and slightly raised.
The rings usually start small and then expand outward.
Ringworm of the body is related to athlete's foot (tinea pedis), jock itch (tinea cruris) and ringworm of the scalp (tinea capitis)..
Ringworm is a common infection of the skin and nails that is caused by fungus.
The infection is called “ringworm” because it can cause an itchy, red, circular rash.
Ringworm is also called “tinea” or “dermatophytosis.” The different types of ringworm are usually named for the location of the infection on the body..

Fungal spores from dermatophytes (ringworm) can be seen within neutrophils, can be free, or can be present within nuclear streaming.
These very small, round organisms have a clear halo and basophilic center ( Figure 11 ).
They are about half the size of an average red blood cell.
Ringworm is diagnosed by fungal culture, examination with an ultraviolet lamp, and direct microscopic examination of hair or skin scale.
Fungal culture of hairs and scrapings from the affected areas is the most accurate method.
Direct microscopic examination of hairs or skin scrapings may allow early diagnosis.
Ringworm is an infection of skin, hair, or claws caused by a type of fungus.
In dogs, about 70% of ringworm cases are caused by the fungus Microsporum canis, 20% by Microsporum gypseum, and 10% by Trichophyton mentagrophytes.
In young or debilitated animals and in Yorkshire Terriers, infection may be persistent and widespread.
The Ringworm RealPCR Panel (Idexx Laboratories) includes ,Microsporum and Trichophyton species real-time PCR tests and performs with greater than 95% sensitivity and 99% specificity.
Results are available in one to three working days, so it may be helpful for diagnosis in patients you want to start treating immediately.
