Nursing Plays a Major Role in Infection Control The Nature of Infection. The straightforward definition of an infection is the entry and multiplication of an infectious agent in the tissue of a host. In other words, an infection is an overgrowth of bad bacteria. The infectious agent is called a pathogen. The presence of a pathogen does not mean that an infection will necessarily begin. The development of an infection happens in a cycle that depends on all elements of the cycle being present. There are six elements in the chain of infection: Infectious agent – A microbial organism with the ability to cause disease.

infection Others define infection as the presence of a microorganism in host tissues whether or not it evolves into detectable pathologic effects. The host may be a bacterium, plant, animal, or human being, and the infecting agent may be viral, rickettsial, bacterial, fungal, or protozoan. A differentiation is made between infection and infestation. Infestation is the invasion of a host by higher organisms such as parasitic worms.
