Bacteria black filled icon

About the Bacteria black filled icon

A circular frame holds a round bacterial cell with a simple smiling face, ringed by alternating spikes: short plain ones and longer stalks tipped with small open circles. The friendly expression softens the subject, making it read as probiotics and good bacteria as much as germs. Use it in hygiene and handwashing campaigns, gut health and supplement apps, biology teaching slides, cleaning product packaging and medical explainers.

Spikes radiate at even angles so the cell stays circular and balanced, and the tipped stalks add texture that distinguishes it from a plain virus dot. It pairs with laboratory, antioxidant and immunity icons of the same weight. Keep it at 32px or larger so the face and spike tips stay legible.

This is the solid black filled version of the bacteria icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
