Môi trường nuôi cấy vi sinh Colorex STEC

COLOREX™ STEC is a chromogenic medium(1) for the detection of enterohaemorrhagic E. coli (including serotypes O26, O111 & O157). Over the past few years there has been an increase in the number of food poisoning outbreaks where non-O157 Shiga toxin producing E. coli (STEC) have been shown to be etiological agent.
The medium contains several selective agents to reduce the level of background flora from the specimen or food
sample. Positive STEC colonies exhibit a mauve colouration enabling easy interpretation amongst other Gram negative bacteria that will exhibit blue or colourless colonies, if they are able to grow on the medium. Gram positive bacteria will be inhibited.
