Tuberculosis

Tuberculosis (TB) is a bacterial infection caused by a germ called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body. TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes or talks. If you have been exposed, you should go to your doctor for tests. You are more likely to get TB if you have a weak immune system. . Symptoms of TB in the lungs may include: - A bad cough that lasts 3 weeks or longer . - Weight loss. - Coughing up blood or mucus. - Weakness or fatigue . - Fever and chills. - Night sweats . If not treated properly, TB can be deadly. You can usually cure active TB by taking several medicines for a long period of time. People with latent TB can take medicine so that they do not develop active TB. Centers for Disease Control and Prevention.  [from MedlinePlus]

Vaccines

Preparations containing substances with antigenic properties administered to activate the immune system, thereby inducing an immune response. Vaccines range from inactivated or attenuated microorganisms (bacteria and viruses), enhanced autologous tumor cells, tumor antigens or epitopes that are used to elicit host immune responses. Vaccines are used for the prevention, amelioration, or treatment of infectious diseases and cancer. [from NCI]

Bacterial Infections

Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods or spirals. They are so small that a line of 1,000 could fit across a pencil eraser. Most bacteria won't hurt you - less than 1 percent makes people sick. Many are helpful. Some bacteria help to digest food, destroy disease-causing cells and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli. Antibiotics are the usual treatment. When you take antibiotics, follow the directions carefully. Each time you take antibiotics, you increase the chances that bacteria in your body will learn to resist them. Later, you could get or spread an infection that those antibiotics cannot cure.

Hemic and Lymphatic Diseases

Hematologic diseases and diseases of the lymphatic system collectively. Hemic diseases include disorders involving the formed elements (e.g., ERYTHROCYTE AGGREGATION, INTRAVASCULAR) and chemical components (e.g., BLOOD PROTEIN DISORDERS); lymphatic diseases include disorders relating to lymph, lymph nodes, and lymphocytes. [from MeSH]

Mycobacteriosis

Mycobacteria are a type of germ. There are many different kinds. The most common one causes tuberculosis. Another one causes leprosy. Still others cause infections that are called atypical mycobacterial infections. They aren't typical because they don't cause tuberculosis. But they can still harm people, especially people with other problems that affect their immunity, such as AIDS. Sometimes you can have these infections with no symptoms at all. At other times, they can cause lung symptoms similar to tuberculosis:: -Cough. -Weight loss. -Coughing up blood or mucus. -Weakness or fatigue. -Fever and chills. -Night sweats. -Lack of appetite and weight loss. Medicines can treat these infections, but often more than one is needed to cure the infection.  [from MedlinePlus]

Interferon

Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions. [from MeSH]

Interferon Type II

The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES. [from MeSH]

Disorder of immune system

Your immune system is a complex network of cells, tissues, and organs that work together to defend against germs. It helps your body to recognize these foreign invaders. Then its job is to keep them out, or if it can't, to find and destroy them. If your immune system cannot do its job, the results can be serious. Disorders of the immune system include: -Allergy and asthma - immune responses to substances that are usually not harmful. -Immune deficiency diseases - disorders in which the immune system is missing one or more of its parts. -Autoimmune diseases - diseases causing your immune system to attack your own body's cells and tissues by mistake.
