Lippincott Illustrated Reviews: Microbiology 4th edition PDF free download – Microorganisms can be found in every ecosystem and in close associ – tion with every type of multicellular organism. They populate he healthy human body by the billions as benign passengers (nor- al flora, see p. 7) and even as participants in bodily functions. For example, bacteria play a role in the degradation of intestinal contents. In this volume, we primarily consider the role of microorganisms (ie, bacteria, fungi, protozoa, helminths, and viruses) in the initiation an spread of human diseases. Those relatively few species of microorganisms that are harmful to humans, either by production of toxic compotmds or by direct infection, are characterized as pathogens.
