Gram-Stained Bacteria Microscopy Image - E. coli Under Microscope #1718159 (License: Personal Use)

This high-resolution microscopy image displays a Gram-stained smear featuring predominantly pink, rod-shaped bacteria indicative of Gram-negative organisms such as Escherichia coli, interspersed with smaller purple cocci suggestive of Gram-positive species like Staphylococcus. The staining contrast highlights cell wall differences, with crystal violet retained in thick peptidoglycan layers (purple) and counterstained safranin revealing thinner walls (pink). A dark artifact or pipette tip appears at the bottom center, common in wet-mount preparations.

Used in educational and clinical microbiology contexts to illustrate Gram staining technique, bacterial morphology, and differentiation between Gram-positive and Gram-negative pathogens; supports lab reports, e-learning modules, and diagnostic reference guides.
