If organisms stained with carbofuchin appear blue at the end of the procedure, it typically indicates that they are not retaining the carbofuchin dye, suggesting they are likely Gram-negative bacteria. In a Gram staining process, Gram-negative organisms do not retain the primary stain and are counterstained with a different dye, often safranin or methylene blue, which gives them a blue or pink appearance. This result contrasts with Gram-positive organisms, which retain the carbofuchin and appear red or pink.
It can be positive or negative, but mostly negative because humans are the biggest predator of earthworms.
