Susceptibility of brain and skin to bacterial challenge
Abstract:
The brain is a uniquely protected organ. Once the protective barriers are overcome, the brain is susceptible to bacterial infection. Using a reproducible rat model, the susceptibility of brain tissue to challenge by S. aureus or E. coli was quantitatively compared to that of skin. Brain was significantly more susceptible to the presence of bacteria than was the skin of the scalp. The development of infection in skin required at least 10(5) organisms, while brain infection could be produced with as few as 100 organisms.

Factors Affecting the Risk of Infection
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...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
