Plate Count Agar
Bacteriology: Cled medium helps to prevent swarming of proteus over the surface of the plate. When this occurs it can overgrow and prevent identification of other organisms which may have been present. Am unaware that there is universal acceptance that this is preferred over mcconkey, and am also not familiar with the frequency with which proteus creates a problem. ...Read more

Jelly - solid or liq: Microbiologists want their bacteria to be on a well-defined, predictable, relatively pure media, so that everyone agrees on the resulting growth pattern, shape, color, etc. Preference is given to solid media (agar plates) or liquid media (broth). Therefore, new media, especially variable in components and textures, are rarely used. ...Read more

Can you tell me in an immunodiffusion test to diagnose histoplasmosis, patient's serum is placed in a well in an agar plate?
Yes, it is: Immunodiffusion is a test where the antigen is placed in the center of the agar plate and the antibodies (Patient's sera that contain antibodies) in wells at the sides of the dish. The antigen and antibodies diffuse from the wells towards each other; where they meet, there forms a band (precipitate) that can be see. No band - negaative. ...Read more
