For instance, Danielle E Campbell et al. reported that the temperate phage, Bacteroides phage BV01, represses the tryptophan-rich sensory protein (TspO) in Bacteroides vulgatus and thereby potentially impacts host bile acid signaling.10Adam G. Clooney et al. demonstrated that in the gut virome of healthy individuals, there exists a consistent set of virulent bacteriophages, which transition to temperate bacteriophages in cases of inflammatory bowel disease (IBD). The gene discussed is TSPO; the disease is inflammatory bowel disease.
