ALBERT STAIN FOR DIPTHERIAE

specialized structures known as metachromatic granules within their cytoplasm. These granules are vital for identification. The Albert stain, designed specifically for this purpose, targets these metachromatic granules, aiding in the precise detection and differentiation of Corynebacterium diphtheriae, the bacterium responsible for causing diphtheria. Nessers’s and Pugh’s stains are also utilized to detect these granules within the bacterial cytoplasmic membrane. These staining methods provide essential insights into these unique structures, facilitating the identification and study of Corynebacterium species based on their distinctive characteristics.
