Basidiomycete fungi were strongly inhibited by the selected Actinobacteria isolates, with G. trabeum and T. versicolor being most inhibited, followed by I. lacteus and T. pal-ustris. Bifidobacteria and Their Health-Promoting Effects. Although Actinobacteria have been shown to make up a small percentage of the total gut microbiota, they are consistently identified in culture-independent and culture-dependent studies of both higher and lower termite lineages (Watanabe et al. Members of the Actinobacteria genus Bifidobacterium22 are believed to be among the first to colonize the gastrointestinal microbiota. In: The International Research Group on Wood Protection, Section 1, Biology: Paper prepared for the IRG48 Scientific Conference on Wood Protection. 2017 Jun;5(3). During the last decade many studies focused the attention on Actinobacteria, especially on their role both in gastrointestinal and systemic diseases and on their possible therapeutic use. The human gut microbiota is considered one of the most fascinating reservoirs of microbial diversity hosting between 400 to 1000 bacterial species distributed among nine phyla with Firmicutes, Bacteroidetes and Actinobacteria representing around of the diversity. Actinobacteria; Bifidobacteria spp. Obesity or HFD consumption has been found to be linked with a decrease in Bacteroidetes, which exerts immunomodulatory effects on host and a higher abundance of Firmicutes that play a role in energy resorption and obesity. USA.gov. 2003, Kaltenpoth 2009, Arango et al. Actinobacteria are a group of Gram-positive bacteria with high guanine and cytosine content in their DNA, which can be terrestrial or aquatic. However, by the third trimester the non-secretor’s gut microbiomes were much lower than their secretor counterparts. © 2018 Editrice Gastroenterologica Italiana S.r.l.

Perler BK, Reinhart EM, Montgomery M, Maynard M, Shapiro JM, Belenky P, Chan PA. AIDS Behav. Actinobacteria Phylum: Although this phylum comprises a very small proportion of the gut microbiome, it fits the criteria for “keystone taxon” due to its positive association with microbial diversity and high level of ecological connectedness. Gut bacterial microbiome dysbiosis in type 2 Diabetes Mellitus (T2DM) has been reported, but such an association with Diabetic Retinopathy (DR) is not known. Accumulating evidence suggests that gut microbiota via the gut-brain axis play a role in the pathogenesis of depression, thereby con … Role of Actinobacteria and Coriobacteriia in the Antidepressant Effects of Ketamine in an Inflammation Model of Depression Addition of insoluble fiber to isolation media allows for increased metabolite diversity of lab-cultivable microbes derived from zebrafish gut samples. 2011 Sep 1;149(1):37-44. doi: 10.1016/j.ijfoodmicro.2010.12.010.

Eat Lots of Fiber. Clipboard, Search History, and several other advanced features are temporarily unavailable. The application of phylogenetic taxonomic procedures led to improvements in the classification of bacteria assigned to the phylum Actinobacteria but even so there remains a need to further clarify relationships within a taxon that encompasses organisms of agricultural, biotechnological, clinical, and ecological importance.
