Wood's lamp examination will reveal bright green to yellow-green fluorescence of hairs infected by M. canis, M. audouinii, M. rivalieri, and M. ferrugineum and a dull green or blue-white color of hairs infected by T. schoenleinii. [8] Individuals with M. canis infection trichoscopy will show characteristic small comma hairs. [9]
Microsporum audouinii fluoresces when examined in ultraviolet light (Wood's lamp). [15] The two main growth media employed to test for M. audouinii are Sabouraud's Dextrose agar and potato dextrose agar. On the former, growth is slow with and poor sporulation with most strains producing a few abortive macroconidia and sparse microconidia. [3]
Wood's lamp (blacklight) examination will reveal a bright green to yellow-green fluorescence of hairs infected by Trichophyton mentagrophytes var. Mentagrophytes, in kerion infection caused by Trichophyton verrucosum Invaded hairs show an ectothrix infection and fluorescence under Wood's ultra-violet light has been noted in cattle but not in ...
A blacklight, also called a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave ultraviolet light and very little visible light. [ 1 ] [ 2 ] [ 3 ] One type of lamp has a violet filter material, either on the bulb or in a separate glass filter in the lamp housing, which blocks most visible light and allows through UV ...
Wood's lamp examination results are inconsistent. Treatment of pitted keratolysis requires the application of antibiotics to the skin such as benzoyl peroxide, clindamycin, erythromycin, fusidic acid, or mupirocin. [2] [5] Prevention efforts aim to keep the feet dry by using moisture-wicking shoes and socks as well as antiperspirants. [2]
Examine the skin under a Wood's lamp (hypomelanotic macules), the fingers and toes (ungual fibroma), the face (angiofibromas), and the mouth (dental pits and gingival fibromas). In infants under three, perform an echocardiogram to spot rhabdomyomas, and electrocardiogram (ECG) for any arrhythmia.

Despite the frequent use of Wood's lamp in the clinical evaluation of ringworm infections, diagnosis of M. canis requires the performance of additional tests given the potential for false positives. [10] Culture of the fungus is most commonly used to evaluate morphological and physiological parameters of growth, and confirm the identity of the ...
