Disease-causing microbes can also be called pathogens, germs or bugs and are responsible for causing infectious diseases. Microorganisms are very diverse. They include all of the prokaryotes, namely the bacteria and archaea and various forms of eukaryotes, comprising the protozoa, fungi, algae, microscopic plants (green algae), and animals such as rotifers and planarians.
