.. _$_03-detail-4-foods-5-onto-probiotics: ==================== Probiotics and Virus ==================== ---------- Probiotics ---------- Probiotic currently is used to name ingested microorganisms associated with beneficial effects to humans and animals. Ontomatica identifies two microorganism classes: `archaea `_ and `bacteria `_ For example, bacteria secrete proteases to hydrolyze (digest) peptide bonds in proteins; to break proteins into their constituent monomers (amino acids). Lactic acid bacteria are gram-positive, lactic acid producing firmicutes used in food fermentation. Examples are dairy products like yogurt. Protease activity contributes to flavor in food products. Ontomatica identifies `lactic acid bacteria (lactobacillales). `_ Ontomatica manages food products where the treatment is fermentation: `lactic acid fermented foods `_ `lactic acid other agent fermented foods `_ `proteolytic fermented foods `_ Similarly, Ontomatica identifies `protease inhibitors `_, their relationships with human disorders, and their relationships with human genes (72 are identified in example). Interactions with human genes are further classified by activity: Affects, Decreases and Increases Activity. ----- Virus ----- Bacteriophage is a virus that infects and replicates within a bacterium. Phages are distributed in human intestines, a bacterial host. Some viruses are beneficial - infecting bacteria that causes disorders. Some viruses are harmful - infecting probiotic bacteria. Ontomatica identifies `bacteriophages `_. Ontomatica identifies specific bacteria, such as `bacteroides `_, infected by bacteriophages.
