Introduction to the Bacteria - Research Paper Example Bacteria differ in their nature as some contain additional features such as flagella, which helps them in moving and protecting the slim capsules. They also exist in varying shapes and sizes because some are rod-shaped, round, comma-shaped and spiral. Some bacteria cause diseases while many others are important to human beings as they support them in living healthily (Storey 339). The useful bacteria exist on the skin surface, genitals and in the intestines. The bacteria found on human skin are important because they clean the waste material on the skin surface hence preventing dissimilar skin infections. The bacteria in the intestine help in the breaking up of food molecules, thus allowing the body to absorb important nutrients (Storey 340). Cause of disease and the interaction Bacterial diseases occur in different forms, therefore, for a person to avoid it, it is vital to have the knowledge concerning the disease. The bacteria cause different types of diseases ranging from skin dis eases to tuberculosis and bubonic plague. It is easy for an individual to get bacterial diseases because bacteria are single-celled microscopic organisms, hence, seeing them with a naked eye is impossible. Bacterial diseases occur because of harmful bacteria, also called pathogenic bacteria, getting into the human body. These bacteria can get in the human body through contamination of bites, eating unhygienic food, sexual contacts with the infected person, sharing needles and touching dirty areas. When these bacteria get into the human body, they initially enter the blood system, where they find a good environment with optimal conditions for growth. Even though their growth rates are low when in blood, they reproduce considerably within a few days (Storey 342). A bacterium is capable of causing diseases such as throat and ear infections to children. In addition, the bacteria can also cause other diseases to adults, for example, tuberculosis, plague, syphilis, and cholera. Bacteria c ause disease because of varying aspects, which include their toxicity, autoimmune activity such as destroying the human body tissues while others can reproduce, hence increasing their presence in the body. This affects the body working mechanisms. Bacteria become harmful to the human body because too many of them produce toxins that have chemicals that cause inflammation and kill nearby cells. These toxins are capable of causing diseases because the bacteria producing them reproduce, hence, increasing the amount of the toxins. Therefore, these bacteria create holes within the cell membranes, killing the cells. Such bacteria negatively affect the immune system of the human body thus leading to internal bleeding and damage to the body. Pathogenic bacteria also culminate in varied infections and diseases in human beings. The bacteria infect the human body, multiplying and reproducing at a very high rate within different vestigial organs (Storey 343). The bacteria also stick on the cell membranes, destroying them and spreading infectious diseases among individuals. In addition, the bacteria found on the skin of humans are also capable of causing different types of diseases. These bacteria are responsible for causing and spreading infectious diseases, which include bubonic plague, a life-threatening disease. Bacteria of Yersinia pestis variety cause this disease. Bubonic plague occurs in different forms commonly spread by rats and fleas and then transferred to the blood system of the human body. The incubation rate of this infection ranges from two to seven days (Storey 343). Cholera is also among the common diseases resulting from bacterial infections.  Ã‚
