There are also other species we can use as model organisms outside of bacteria but as a replacement for animal system. For example, in the past I've used an amoeba called Dictyostelium. Its a great little diverse amoeba which can be used to study both protozoan diseases and human. In pharmaceuticals we can use this species (and others) to test novel compounds for specific diseases. This reduces animals needed in research but not completely eliminates it.
