Human Gut Bacteria Have 'Sex' to Share Vitamin B12

Pixabay Researchers at the University of California Riverside (UCR) have found that human gut bacteria have sex to pass or share vitamin B12 with each other.   Vitamin B12 is one of the essential nutrients that is required for the growth and development of different body parts, including the brain, blood cells, nerves, in humans. Without this nutrient, many living cells, including, bacteria can not function. Thus, beneficial gut bacteria share the ability to capture this nutrient with one another. "The process involves one cell forming a tube that DNA can pass through to another cell," said Patrick Degnan , UCR microbiologist and study head. "It's as if two humans had sex, and now they both have red hair." Scientists have been aware of this process for years. They knew that 'jumping genes' were responsible for transferring DNA between organisms. Many studies have shown that these genes helped bacteria stay alive in the presence of antibiotics (medicine
