OPTIONS
(A) Microsporum equi
(B) Microsporum canis
(C) Microsporum distortum
(D) Microsporum audounil
ANSWER
(A) Microsporum equi
EXPLANATION
Microsporum equi is classically reported as non-fluorescent under Wood's lamp, whereas some Microsporum species, particularly M. canis, commonly produce apple-green fluorescence in infected hairs. Therefore option A is correct; the other listed Microsporum species are more likely to show fluorescence in the classical descriptions.
