About the Infection Spiral Bacterium black filled icon

A curved rod shaped bacterium fills the frame, its body speckled with dashes and small ringed dots and its whole outline fringed with straight flagella. It reads as bacterial infection, gut microbes and pathogens such as H. pylori, and suits medical and gastroenterology sites, lab reports, hygiene campaigns, biology teaching material and pharmaceutical packaging.

The comma-like body sweeps diagonally across the square, and the evenly spaced hair-like flagella radiate outward to suggest movement. Pair it with virus, microscope and petri dish icons, and give it 48 px or more so the thin flagella do not disappear.

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