What intestinal bacteria are there?
Numerous different types of intestinal bacteria live in the human intestinal tract. Together with other microorganisms, they form the intestinal flora, which performs vital functions in human digestion, but also in immune defense. Bacteroides, lactobacilli, streptococci, enterococci, clostridia, fusobacteria and veillonella are common representatives of the intestinal bacteria. The total number of mainly anaerobic intestinal bacteria in an adult is estimated to be between 10 and 100 trillion. The total weight of a person's intestinal bacteria makes up one to two kilograms of their body weight. The large intestine is the most densely populated place. There are hundreds of billions to a trillion gut bacteria on one gram of feces.
Symptoms of bad gut bacteria
In healthy people, the intestinal bacteria live together in a natural balance. Diseases, medication, stress and unhealthy nutrition can upset the balance of the intestinal bacteria and lead to an increase in pathological intestinal bacteria. These include, for example, Salmonella, Shigella, Enterohaemorrhagic Escherichia coli (EHEC) and Yersinia enterocolitica. This can lead to a number of complaints such as bloating, abdominal pain, diarrhea, constipation, recurrent gastrointestinal disorders, food intolerance, constant fatigue, headache and fungal infections.
