Cutaneous Coinfection of Cytomegalovirus and Mycobacterium chelonae Accelerated by Immunosuppression

Figure 5

Colonies of Mycobacterium chelonae on 2% Ogawa medium ((a) gross appearance, (b) Ziehl-Neelsen stain, (c) Gram stain, and (d) MALDI Biotyper analysis). Smooth-surfaced white (nonchromogenic) colonies are formed seven days after inoculation. The formalin-fixed, paraffin-embedded colonies display acid-fastness and Gram reactivity of the rods. By the MALDI biotyping analysis, the spectrum pattern indicates M. chelonae with the log score value of 2.208.
