題目提到用伍氏燈無螢光反應，在搭配鏡檢的圖做為評估：(A)參考：https://www.youtube.com/watch?v=-Bol6RtEp24(B)However, not all M. canis strains and none of the Trichophyton spp. of veterinary importance produce fluorescence; thus, absence of fluorescence does not discount a diagnosis of dermatophytosis.參考：https://www.rvc.ac.uk/review/dermatology/tests/WoodsLamp.htm參考：https://zh.wikipedia.org/wiki/%E6%AF%9B%E7%99%AC%E8%8F%8C%E5%B1%AC(D)Infection by this species can often be detected clinically using Wood's lamp, which causes infected tissues to fluoresce bright green[4][9] 參考：https://www.wikiwand.com/en/Microsporum_canis
