How the Body Works How Bacteria Cause Disease

Bacteria usually gain entrance to the body either by inhalation, by ingestion, or through a break in the skin. Once they have entered a tissue, the bacteria may produce a substance known as the spreading factor. The spreading factor digests connective tissue barriers in the tissues, thus allowing further spread of the bacteria or their toxins. Failure to overcome these invasive agents can lead to severe tissue damage. Large numbers of bacteria may compete with the healthy cells for nutrients and oxygen. Toxins, on the other hand, disrupt normal cell metabolism by interfering with chemical reactions. When a tissue becomes infected by bacteria, white blood cells migrate to the site of infection and begin to ingest the bacteria. The bacteria, however, may survive and multiply within the white cells, which then burst, releasing the bacteria into the tissue once again, causing severe inflammation. More white cells then enter the area to try to combat the infection. White blood cells are attracted to an infected site where bacteria are multiplying and causing inflammation. Some bacteria have thick capsules around them which prevents them from being engulfed, consequently, the bacteria increase. The body then manufactures antibodies which attach themselves to the bacteria, making them vulnerable to ingestion by the white cells. In this illustration the infected site is supplied with white blood cells. The bacteria have gained entry by a small cut in the skin and are beginning to multiply and grow rapidly, secreting toxins which can act locally or can enter the general circulation to be widely dispersed, causing the death or malfunction of the body cells. If the white cells fail to combat the bacteria in the initial stages, then tissue damage may occur. If they initially fail to destroy the bacteria, then the bacteria increase in number and finally begin to break up, releasing toxic chemicals, called endotoxins, which are contained with their walls. The released endotoxins may cause local tissue damage.

  • Viral diseases (including my own case of severe CFS) have no chance with blood electrification, search Bob Beck right here on Youtube! Visit my channel for a link to more info.

  • @unleashhealth I watched the video and it looks like the device will increase to body's voltage - hopefully enough to electrocute the virus with electrophoresis activity ? If you need a Patent protection, priority dates , in 1998 I invented the Zinc Carbon pill a year after the Method of Curing AIDS With Tetra Silver Tetroxide Molecular in 1997. I didn't know about that at the time . my research used dozens or electro chemicals and processes - the danger I researched was liver kidney damage

  • The most healthy people i have known are people that are in constant exposure to microorganisms like doctors or farmers and the like, they almost never get sick so don't live too "healthy".

  • WHOOT! Polymorphoneuclear neutrophils, those are. SEGS! Go gettum segs, kick those prokaryotic asses...

see all

  • my goodness....

  • @PyramidHead17 i know im being dumb for replying to 1 year old comments but yh ur soo right it seems that all the people who are good and very healthy are unlucky... im not a very good nerdy person but ive never been hurt badly like broken my arm but all my good friends do and ive always seen the people who are too healthy get sick... so yh be a bit fat or summin A BIT...

  • Good video.

  • does the cut matter how bout if the cut was just a cute can still enter it. does how deep the cuts matter and can bacteria be found on the tissue like.

  • wheres my quick list?

  • you should make the pics move that way we know how they rly move

  • Perfectly put!

  • a nice way to know abt the action of bacteria
