This is one of the most common disease which is caused by bacteria. The bacterium which is responsible for the outbreak of this disease is called as mycobacterium tuberculosis. Tuberculosis is reported to be an infectious disease. People who are suffering from TB or tuberculosis are known to cough repeatedly. Pain in the chest has also been experienced by TB patients. Fever is known to persist in the affected person and coughing of blood has also been widely reported. In addition to this, weight loss and fatigue are also known to exist in TB patients. Tuberculosis also affects the skin and bones either directly or indirectly.

  • Cholera

Another disease caused by bacteria is cholera which is generally an intestinal infection that is said to be caused by a bacterium which is better known as vibrio cholera. This bacteria is known to contaminate food stuffs and water. When a person consumes this contaminated food, then he/she is affected by cholera. The symptoms of cholera sets in only after some 2 or 3 days after the infection has spread to the entire body. Some of the symptoms include diarrhea, abdominal cramps, dryness in the mouth and skin, low levels of urination, nausea and fatigue. If timely treatment is not given, then the patience has a 100% risk of dying due to this disease.

  • Pertussis

The bacteria that is responsible for causing this disease is known as bordetella pertussis. Pertussis is also referred to as ‘whooping cough’. This disease is reported to be fatal in the case of small children as it affects the immune system and makes it vulnerable to attacks from several other diseases. Frequent coughing  prevails in the case of the affected people. This disease is usually prevalent in countries that are highly underdeveloped and where the cost of necessary medicines are relatively high.

  • Bubonic plague

Bacteria is again responsible for causing this disease which poses as a threat to life if proper medication is not given. This disease is caused by the bacterium yersinia pestis. This bacteria generally spreads through fleas, rats and other rodents. This disease can exist in several forms. One common form is sepsis in which the bloodstream of the affected person becomes contaminated. It is usually harmful and fatal. Another form is the abortive form which is regarded to be relatively harmless because it causes only fever which subsides after a few days after the intake of proper antibiotics and medicines.

  • Typhoid

One of the more common diseases caused by bacteria is caused by the popular bacteria called salmonella typhi. Typhoid is generally an acute illness which is contracted by the presence of this bacteria in contaminated food or water. Persons who are suffering from typhoid can spread the disease causing bacteria to the surroundings through the stools which is reported to contain large amount of this harmful bacteria. This bacterium can survive in sewage and other garbage for several weeks before it perishes. Poor appetites, headaches, vomiting sensation and fever are some of the common symptoms of typhoid.
Thus, some of the common diseases that are caused by bacteria have been discussed.
