The immune system attacks the foreign antigen as if it were any bacterial infection. The B-cell lymphocytes mark the TB with antibodies that helps it remember the bacteria in the future. The macrophage then consumes the TB bacteria and keeps it latent, and the TB is unable to infect the body or be contagious. However, if the immune system fails to contain the TB, or it becomes weakened by age, malnutrition or another disease like AIDS, the TB bacteria can escape and infect the body, which is why people can get TB during old age or without a TB infected person coming in contact with them.
The body defends itself against disease through the immune system, which includes various types of immune cells like white blood cells and antibodies. These cells recognize and eliminate foreign invaders such as bacteria, viruses, and fungi to protect the body from infections. The immune system also produces memory cells that help to remember and respond faster to previously encountered pathogens.

One way the body protects itself against microbes is with the cell membrane. The cell membrane is like a body guard, it lets certain cells, and virus's in. Another way the body can protect itself is with the white blood cell. The white blood cell defends the body against microbes.
the bacteria attaches itself to healthy cell and slowly destroys them when they multiply. this is also true for viruses. when you feel bad or sore throat, that is simply the bacteria/virus being fought off.
The body defends itself against allergens by producing antibodies called immunoglobulin E (IgE) that bind to the allergen. This triggers the release of inflammatory chemicals, such as histamine, which cause allergy symptoms like itching, swelling, and mucus production. Antihistamines can help reduce these symptoms by blocking the effects of histamine.

White blood cells
The immune system is the body system that defends against infection and disease by identifying and fighting off harmful pathogens such as bacteria, viruses, and other pathogens. It consists of a network of cells, tissues, and organs that work together to protect the body.
Your body defends against chlamydia in a number of ways:Intact, healthy skin prevents entry of the germ;Blood lymphocytes and T cells fight the bacteria after infection;Humoral factors also fight infection.see related link
Skin is the smooth external coat or covering for vertebrates. It is engaged in protecting the body from pathogens that causes illness.
