Bacterial Infection Bacillus black outline icon

About the Bacterial Infection Bacillus black outline icon

A single curved rod-shaped bacterium is drawn with short hair-like flagella around its whole body and six small rings inside the cell wall. It represents bacterial infection, germs, microbes and pathogens, which makes it useful for medical and lab websites, gut health and probiotic packaging, pharmacy apps, patient education leaflets and biology teaching slides about microorganisms.

The body is a slightly bent capsule, and the evenly spaced flagella radiate outward to give a bristled silhouette that reads as a microbe even at a glance. Pair it with virus, petri dish, antibiotic and stomach icons. Because the flagella are thin strokes, keep the icon at 40px or larger in print and on screen.

This is the black outline version of the bacterial infection bacillus 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.
