Bacteria belong to the Bacteria domain, whereas fungi (yeasts and molds), protozoa, and helminths (worms) are classified in the Eukarya domain (Table 1–1). Protists and fungi are distinguished from animals and plants by being either unicellular or relatively simple multicellular organisms. In contrast, helminths are complex multicellular organisms. Viruses are quite distinct from other organisms. They are noncellular; that is, they do not have a nucleus and cytoplasm, cannot make their own energy, and are unable to synthesize proteins. They are completely reliant upon host cells for replication and are thus considered obligate intracellular pathogens.
