Here, the immune system adapts its response during an infection to improve its recognition of the pathogen. This improved response is then retained after the pathogen has been eliminated, in the form of an immunological memory, and allows the adaptive immune system to mount faster and stronger attacks each time this pathogen is encountered.

In immunology, systemic inflammatory response syndrome (SIRS) is an inflammatory state affecting the whole body. [1] It is the body's response to an infectious or noninfectious insult . Although the definition of SIRS refers to it as an "inflammatory" response, it actually has pro- and anti-inflammatory components.

Not only does this make it more difficult to fight the infection, it may mean that a level of infection that would normally produce symptoms is instead undetected (subclinical infection).
The more commonly used term is nontuberculous mycobacteria (NTM) infection, or non-tuberculous mycobacterial infection (NMI).
