Neisseria gonorrhoeae growth on chocolate agar. (A) Colonies of N. gonorrhoeae on chocolate agar show a small, translucent, and smooth morphology with a grayish‐white color. (B) Gram staining of bacterial smears from the colonies reveals characteristic Gram‐negative diplococci morphology. These findings confirm the presence of N. gonorrhoeae in the cultured sample. (C) API® NH strip results for the identification of N. gonorrhoeae. The API® NH strip reactions are shown for each well (W1–W13) of the strip. Positive reactions are indicated by a color change. (W1: penicillinase positive, W2: glucose positive, W3: fructose negative, W4: maltose negative, W5: sucrose negative, W6: ornithine decarboxylase negative, W7: urease negative, W8: lipase negative, W9: alkaline phosphatase negative, W10: β‐galactosidase negative, W11: proline arylamidase positive, W12: gamma glutamyl transferase negative, W13: indole negative). These reactions confirm the presence of N. gonorrhoeae in the tested sample, consistent with the known biochemical characteristics of the pathogen.
