BBL™ Methylene Blue Loeffler Stain Droppers are used for presumptive identification of
Corynebacterium diphtheriae and as an adjunct to the Gram stain.
Methylene Blue is recognized as a simple stain that can be used for a variety of purposes, such as determining bacterial morphology and aiding in the interpretation of the Quellung test.1 It is the stain of choice for the presumptive identification of Corynebacterium diphtheriae. Upon staining, this species is characterized by a beaded or banded appearance of the cell, with deeply stained metachromatic granules contrasted with a lighter blue cytoplasm.2,3 Methylene Blue is used as an adjunct to the Gram stain, especially in the staining of gram-negative bacteria such as Haemophilus influenzae and Neisseria species.4,5 The stain can reveal the morphology of fusiform bacteria and spirochetes (from oral infections such as Vincent's angina) that may be difficult to see with the Gram stain.5 The stain is also used to detect the presence of fecal white blood cells that may show the presence of invasive bowel disease.5 BBL Methylene Blue Loeffler Stain Droppers can be used as a counterstain with BBL Flagella Stain Droppers, which are recommended for staining the flagella of bacteria. BBL Methylene Blue Loeffler Stain Droppers are supplied in a hermetically sealed ampule for improved stability of the reagent prior to use.
