Bacteria black filled icon
Round microbe cell with three inner dots and eight spikes ending in small circles
About the Bacteria black filled icon
A circular cell body holds three small dots inside it and sends out eight straight spikes, each ending in a tiny circle, giving the germ a spiky radial shape under a microscope. It labels content on infection and hygiene campaigns, medical and pharmacy apps, laboratory and biology teaching slides, cleaning product packaging and antivirus or health warning screens.
The spikes alternate in length so the outline stays lively rather than mechanical, and the interior dots suggest cell structure without clutter. It pairs with microscope, vaccine and hand washing icons; keep clear space around it so the spike tips are not cropped.
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.
