The idea of bacteria in ones immune system may cause some concern, however, some new research has found that certain types can boost immunity, according to a study published in the Journal of Immunology.
Researchers have discovered that while some bacteria can lead to infections, other forms are either harmless or even beneficial to the human body.
Using mice that were bred in sterile environments, a team of investigators introduced certain types of bacteria to the animals to see if they could boost immune system health. Among the different forms used, researchers exposed the mice to Bacillus, a rod-shaped bacteria that is located in the digestive system.
The results of the study showed that when the animals were exposed to Bacillus, their immune system cells began to reproduce. Also, the team discovered the formation of small antibodies in the immune system, which can help stave off viruses and forms of bad bacteria.
The researchers concluded that in the future, these findings could lead to the use of bacterial spores to treat newborns, elderly patients and people undergoing bone marrow transplant procedures.
Many studies have also found other health benefits of bacteria, such as the use of probiotics, which are living bacteria that are found in milk and yogurt. In addition to helping the immune system, probiotics can prevent the development of inflammatory bowel disease, according to research from the University of Chicago.
