The Body's Cellular Response to Bacterial Infection

Bacterial infections occur when single-celled organisms, bacteria known to colonize the human body. Although the colonization, as a rule, dismissed the immune system, bacteria cause disease when they can not be controlled and begin to interfere with normal function. Bacteria can penetrate virtually any body system, and make it through many routes of entry. Some types of bacteria that normally live in symbiosis with human beings, especially in the skin and intestines, but it can lead to disease when they grow out of control, or enter parts of the body where they are usually not found (www.wisegeek.com).

There are millions of different species of bacteria, but few make up the majority of infections in humans. It is difficult to quantify how much disease is caused by a bacterial infection, but it matters. The human body has a number of strategies to fight infections or prevent them. All of our fight against infection apparatus called the "immune system". The immune system of the human body not only include white blood cells that are trying to catch and kill microbes, but also a number of mechanisms that stop germs from the establishment of infection (WWW. Ableweb.org).

In most cases, people have certain characteristics in their bodies, called innate immunity, allowing the authorities to combat infections, virtually all times. For example, the skin, our largest organ, is constantly fighting infection or avert infection, acting as a barrier against foreign, not human cells. Other parts of our body, or the content of the body is always on guard to fight infections (www.wisegeek.com).

Intestines and stomach contain mucus, which can trap a small number of foreign bacterial cells, keeping the body from infection. The human body using various acids in the organs, which create an environment ...
