SUPERFICIAL INFECTION BY CANDIDA SPP CONTRASTED WITH MALASSEZIA SPP Figure 22-11 SUPERFICIAL INFECTION BY CANDIDA SPP CONTRASTED WITH MALASSEZIA SPP Malassezia spp (B) are typically found on sebum-rich skin and do not reveal the periodic filamentous constrictions often seen in Candida spp (A), which impart a slightly more irregular morphology to these organisms.
