Leptospire can cause various diseases in animals and humans.
Leptospire → It is formed from "lepto-" (from Greek "leptos", meaning thin or slender) and "spire" (from Latin "spira", meaning coil or spiral). The word describes a thin, spiral-shaped bacterium.
Think of something that is 'thin' ('lepto-') and 'spiral' ('spire') — that's why leptospire refers to a slender, spiral-shaped bacterium.
