Bacteria black outline icon

About the Bacteria black outline 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 black outline version of the bacteria icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
