Rod-Shaped Bacteria Micrograph - E. coli and Common Bacilli #177414 (License: Personal Use)

This black-and-white micrograph displays numerous Gram-negative bacilli, predominantly Escherichia coli, scattered across the field with varying orientations and lengths. Some cells appear in short chains or pairs, indicating binary fission activity, while others are isolated; slight variations in staining intensity suggest differences in cell wall integrity or phase. The image captures typical morphological features used in clinical and research microbiology for preliminary identification.

Used in educational materials, medical textbooks, and diagnostic lab websites to illustrate bacterial morphology, especially for teaching Gram staining interpretation and identifying enteric pathogens. Matches user intent for academic study, lab reference, or科普 content on microbiology.
