Infection and iron metabolism
Abstract:
An important component of nonspecific defense of vertebrates against microbial invasion is that of nutritional immunity. Hosts attempt to withhold growth-essential iron from invading bacteria, fungi, and protozoa. Clinical conditions in which hosts are stressed by excess quantities of iron in specific fluids, tissues, or cells result in enhanced susceptibility to infection. Methods for strengthening nutritional immunity are known in theory; research is needed to determine if these would be useful in clinical practice.

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
