Acanthamoeba castellanii

Acanthamoeba castellanii is a type of single-celled organism known as an amoeba, found widely in the environment like water, soil, and air. It has a flexible shape and moves using tiny projections called pseudopodia. Although often harmless, it can sometimes cause infections in the eyes, skin, and nervous system, especially if contaminated water enters the eyes or wounds. It plays a role in ecosystems by breaking down organic materials. Studying it helps scientists understand more about amoebas, environmental health, and how to prevent related infections.
