'Dialister' is a genus of Firmicutes bacteria classified within the class Negativicutes.
A new study of two large groups of Europeans, led by Dr. Sara Vieira-Silva and Dr. Jeroen Raes from the Catholic University of Leuven (Belgium), has found new links between gut microbes and depression. Dialister and Coprococcus genera were reduced in people with depression. [Nat Microbiol. 2019. doi: 10.1038/s41564-018-0337-x] This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072] Abundance of the genus Dialister was found to be positively correlated with the Ankylosing Spondylitis Disease Activity Score (Spearman's rho = 0.62, false discovery rate–corrected q < 0.01). This finding was further supported by the low frequency of Dialister observed in noninflamed ileal and colonic biopsy tissue from patients with SpA and healthy controls.
