Microbial infections are caused by pathogenic microorganisms, including bacteria, viruses, fungi, and parasites, that invade the body and cause diseases. The body has evolved a sophisticated immune system to detect and eliminate these pathogens. Immunological control refers to the mechanisms by which the immune system defends the body against microbial infections, both through innate immunity (the first line of defense) and adaptive immunity (a more specific and targeted response).
The interplay between microbial infections and immunological control is critical in determining the outcome of infections. A well-functioning immune system can effectively neutralize pathogens, while a compromised or dysregulated immune system can lead to chronic infections, tissue damage, or immune-related diseases.
