Host pathogen Interaction

The host–pathogen interface is distinct as how microbes or viruses sustain themselves within host organisms on a molecular, cellular, organismal or population level. This tenure is most usually used to refer to disease-causing microorganisms although they may not cause illness in all hosts.  Because of this, the definition has been expanded to how known pathogens survive within their host, whether they cause disease or not. On the molecular and cellular level, microbes can infect the host and divide rapidly, causing disease by being there and causing a homeostatic imbalance in the body, or by secreting toxins which cause symptoms to appear. Viruses can also contaminate the host with contagious DNA, which can affect normal cell processes ,protein folding, or evading the immune response.
