What are the different types of bacteria in the digestive system?
bacteria in the digestive system number in trillion and most of these bacteria are referred to as friendly. Some experts say that friendly bacteria have a symbiotic relationship with their human hosts because they help the human body in different useful ways. Other types of bacteria in the digestive system are not so friendly, including those that produce cholera, botulism and salmonellosis.
different estimates indicate that there are 300 to 1,000 bacteria species in the digestive system. In general, these bacteria, also known as intestinal flora, help the body in many ways that include help in digestion, strengthening the immune system and blocking the growth of enemy organisms. Friendly bacteria mostly live in the large intestine and part of the small intestine. The acidic environment of the stomach does not contribute to bacterial growth.
bacteria are beginning to fill the human digestive system immediately after birth. One of the most common bacteria, according to experts, is bacteroides . These bacteria help indigestion of plant foods such as spinach. bacteroides release the enzymes that the human body lack, thereby absorbed nutrients from plant foods. The human body acquires vitamin K and some vitamins B as a result of work bacteroides .
Lactobacillus is another type of friendly bacteria. Found in many foods such as yogurt, beer, wine and chocolate, bacteria lactobacillus have a reputation to help the immune system and discourage diseases such as flu. Some research seems to indicate that Lactobacillus also has the properties of the fight against cancer. It has been shown that lactobacillus inhibits tumor growth when it is given to animals.
Some bacteria in the digestive system have the reputation of being very hostile and causing a lot of confusion. Examples include vibrio cholera , Clostridium botulinum and severalTypes of Bacteria Salmonella . Diseases caused by these bacteria can sometimes be deadly.
vibrio cholera , source of cholera can be spreading drinking water. His symptoms include diarrhea and dehydration, with severe dehydration is one of the most common causes of death from this disease. Clostridium botulinum produces very deadly botulism disease by releasing toxins, which in addition to diarrhea and vomiting can initiate muscle paralysis, blurred vision and respiratory problems. Salmonella poisoning causes vomiting and diarrhea that occurs when eating infected eggs, meat and processed foods. These bacteria create a disease that is limiting, which means that the body will usually fight itself.
