Background: Gram staining is a key technique in microbiology that allows bacteria to be classified into two groups: Gram-positive and Gram-negative. This staining method, developed by Hans Christian Gram in the late 1800s, gives vital insights into bacterial cell wall composition and has become a cornerstone of bacterial identification and classification. The differential staining is
