What are ringworms in cats glowing with? - briefly
Ringworms in cats glow due to the presence of certain proteins called keratins, which fluoresce under specific wavelengths of light, often seen as a greenish-yellow hue. This glowing effect is not visible to the naked eye but can be detected using specialized equipment like Wood's lamp.
What are ringworms in cats glowing with? - in detail
Ringworm in cats, also known as dermatophytosis, is a fungal infection that can cause distinct symptoms, including areas of hair loss and skin inflammation that may appear to "glow" under certain conditions. This characteristic glow is due to several factors:
-
Fluorescence: The fungi responsible for ringworm, such as Microsporum canis and Trichophyton mentagrophytes, contain natural fluorescent compounds called pteridines. When exposed to ultraviolet light, these compounds emit a greenish-blue glow, making the affected areas more visible.
-
Inflammation: The infection triggers an immune response in the cat's body, leading to inflammation of the skin and hair follicles. This inflammation can cause the skin to appear reddened or have a slightly different texture, which may contribute to the perception of "glowing."
-
Hair Loss: As the fungus grows and damages the hair follicles, the cat experiences hair loss in circular patterns, creating bald spots that are often more noticeable due to the contrast with the surrounding fur. These areas may appear smoother or shinier compared to unaffected skin, giving the impression of glowing under certain lighting conditions.
-
Skin Changes: The fungal infection can alter the structure and appearance of the cat's skin, making it look different from normal skin. This change in texture and color can create an illusion of glow, especially when viewed under specific light sources.
-
Wood's Lamp Examination: Veterinarians often use a Wood's lamp, which emits UV-A light, to diagnose ringworm. The natural fluorescence of the fungi makes the affected areas more visible under this light, further enhancing the appearance of glowing.
Understanding these factors helps in accurately identifying and treating ringworm in cats, ensuring their well-being and preventing the spread of the infection to other pets or humans.
