Introduction: Immunity is a state of a specific resistance to infection. Specific resistance is directed against a particular type of microorganism and is a one of the most important characteristic of the immunity. The Immune System is a system of biological structures that processes in an organism that protects in diseases. It is functioning properly if it has a wide variety of agents known as pathogens from the viruses and parasite worms, and known them from the organisms healthy tissue.

Like all blood cells, leukocytes originate from the bone marrow. Stem cells (undifferentiated cells) in the marrow develop into the various white blood cells. In addition to serving as the birthplace for leukocytes, the bone marrow also acts as a reservoir for mature cells that may be needed in event of infection or blood loss. Although most leukocytes originate in the bone marrow along with red blood cells, most spend very little time in the blood. Leukocytes spend most of their time in storage, in lymphoid tissues (see below), or dispersed throughout the host tissues. Leukocytes use blood mainly as a transport system to travel to areas of the body where they are needed. There are six families of leukocytes that have distinct roles in the body’s defense. These are the monocyte-macrophages, dendritic cells, mast cells, granulocytes, lymphocytes, and natural killer cells. All the leukocytes except the lymphocytes are considered part of the innate immune system. Lymphocytes are the only leukocytes associated with

The most common symptoms of flu are fever, sore throat, muscle pains, head-aches, cough, and fatigue. It is like a common cold, but it is more severe disease. It may also cause vomiting, particularly in children and it is more common in them, which is sometimes referred to as stomach flu. Typically, it is transmitted through the air by cough or sneezes, containing some aerosols that is containing the virus. It affects the immune system by a virus that enters our body. One way your body fights influenza infections is by developing antibodies to the hemagglutinin on the virus. When antibodies attach to hemagglutinin, they keep the virus from attaching to healthy cells. This keeps the virus from infecting these cells.

Bacteria

Legionella

The legionella is a pathogenic group of gram-negative bacteria. It can be seen by a single stain. It is common found in many environments, including soil and mostly in other aquatic systems. It acquired its name after a July 1976 outbreak of an unknown mystery disease that sickened 221 persons, that cause 34 deaths. the bacteria reproduce to high numbers in warm, stagnant water (95 F-115 F), such as that which is found in certain plumbing systems and hot-water tanks, cooling towers, and evaporative condensers of large air-conditioning systems, and whirlpool spas.
