Once a bacterium recognizes the host cell receptors or nutrient-rich surroundings, it colonizes the cell surface. [3] Bacteria have various mechanisms for colonizing host tissues. For example, biofilm production allows bacteria to adhere to the host tissue surface, and it provides a protective environment ideal for bacterial growth. [4]
The host-pathogen interaction is defined as how microbes or viruses sustain themselves within host organisms on a molecular, cellular, organismal or population level. This term is most commonly used to refer to disease-causing microorganisms although they may not cause illness in all hosts. [ 1 ]
Host factors that may vary in a population and affect disease susceptibility can be innate or acquired. Some examples: [1] general health; psychological characteristics and attitude; nutritional state; social ties; previous exposure to the organism or related antigens; haplotype or other specific genetic differences of immune function ...
Definitive or primary host – an organism in which the parasite reaches the adult stage and reproduces sexually, if possible. This is the final host. Secondary or intermediate host – an organism that harbors the sexually immature parasite and is required by the parasite to undergo development and complete its life cycle. It often acts as a ...
Other intracellular parasites have developed different ways to enter a host cell that do not require a specific component or action from within the host cell. An example is intracellular parasites using a method called gliding motility. This is the use of an actin-myosin motor that is connected to the intracellular parasites' cytoskeleton.
