Bacteria

Organisms that cause diseases are known as pathogens. The pathogenic organisms are bacterİa, fungi, protozoans and viruses. Pathogens enter the body through the air, water and food. Using unwashed dishes, eating with dirty hands or sneezing spread pathogens. Bacteria are a group of pathogens. Theyare one-celled organisms that live best in warm, dark and moist places such as the human body. After a bacterium enters the body it reproduces. When many bacteria are present diseases may develop. Some bacteria cause disease by damaging cells while others give out wastes (toxins) that poison the body.

Cholera, diphtheria, pnemonia, scarlet fever, tetanus, tuberculosis, typhoid fever and whooping cough are all caused by bacteria. Viruses are pathogens that cause chicken pox, the common cold, influenza, mumps, polio, rabies, hepatitis and AIDS (Acquired Immune Deficiency Sendrome).

Communicable diseases are diseases that spread from one person to another such as cholera, tuberculosis, common cold and influenza.
