Chocolate agar (CHOC) - is a non-selective, enriched growth medium. It is a variant of blood agar plate, and it contained the red blood cells, which have been lysed by heating very slowly to 56 °C. Chocolate agar is used for growing fastidious (fussy) respiratory bacteria, such as Haemophilus influenzae. These bacteria needs growth factory, like NAD, which are inside erythrocytes, and they can growth not before haemolysis. No chocolate is actually contained in the plate, it is named for the coloration only.

In this medium every bacteria can growth, so culture from faeces is impossible.
