Growth of Capnocytophaga canimorsus on Columbia blood agar of two different manufacturers. Positive blood cultures were inoculated on Columbia Agar with 5% sheep blood from (a) BD and (b) Oxoid. The inoculum of pure cultures was standardized (McFarland 0.5) and sub-cultured on Columbia blood agar from (c) BD and (d) Oxoid. The comparison of the media from two manufacturers revealed a (b) weaker or (d) absent growth on agar plates from Oxoid
