Bacterial infection

Genetic analysis provides evidence that the origin of bacteria in blood infections is in a capsule of a probiotic preparation. In the illustration you see a capsule from which blue probiotic bacteria are dispersed. You can see that they reach the blood vessels (infection). The tree (black) that connects the bacteria represents the phylogenetic relationship between the bacteria, that is, the genetic analysis performed by the researchers. Credit: Barak Sha'er Tamar
