Pyrosequencing analysis of intestinal microflora from healthy Thai vegetarians and non-vegetarians exhibited 893 OTUs covering 189 species. The strong species indicators of vegetarians and non-vegetarians were Prevotella copri and Bacteroides vulgatus as well as bacteria close to Escherichia hermanii with % relative abundance of 16.9 and 4.5-4.7, respectively. Core gut microbiota of the vegetarian and non-vegetarian groups consisted of 11 and 20 different bacterial species, respectively…

Characteristics of the Gut Bacterial Composition in People of Different Nationalities and Religions

TLDR
The gut microbiota of people of different nationalities and religions are influenced by food preferences, and the influences of pathologies such as obesity, Crohn’s disease, cancer, diabetes, etc., are considered.

Age-related changes in the gut microbiota and the core gut microbiome of healthy Thai humans

TLDR
In the gut of Thai adults, Bifidobacterium decreased and Bacteroides increased with age, while rice consumption increased the abundance of Bactelloides, suggesting link of age and food, especially rice carbohydrate, to gut microbiota and health could be ultimately proposed as the Thai feature.

The Effects of Vegetarian and Vegan Diets on Gut Microbiota

TLDR
The available literature suggests that a vegetarian/vegan diet is effective in promoting a diverse ecosystem of beneficial bacteria to support both human gut microbiome and overall health.

Is a vegan or a vegetarian diet associated with the microbiota composition in the gut? Results of a new cross-sectional study and systematic review

TLDR
No consistent association between a vegan diet or vegetarian diet and microbiota composition compared to omnivores could be identified and standardized methods with high taxonomical and functional resolutions are needed to clarify this issue.

Lower Circulating Branched-Chain Amino Acid Concentrations Among Vegetarians are Associated with Changes in Gut Microbial Composition and Function.

TLDR
It is indicated that gut microbiota plays an important role in the modulation of circulating BCAAs among vegetarians and omnivores and in line with the lower concentrations of BCAA, metatranscriptomic analysis showed that the gut microbial pathway for the degradation of B CAAs was significantly upregulated among vegetarian compared with the omnivore.

Similarities and differences in gut microbiome composition correlate with dietary patterns of Indian and Chinese adults

TLDR
An important role of diet in determining gut bacterial composition is confirmed, using next-generation sequencing analysis on IlluminaHiSeq 2500 platform to reveal unique community structure, dominant Firmicutes, Actinobacteria and underrepresented Bacteroides of Indian and Chinese gut bacteria.

Opportunistic pathogens are abundant in the gut of cultured giant spiny frog (Paa spinosa)

TLDR
A method to forecast the pathogenic infection risk of cultured P. spinosa, which could guide the artificial culture of and prevent diseases in P.–spinosa through gut microbiota, was provided.

The Potential of Pectins to Modulate the Human Gut Microbiota Evaluated by In Vitro Fermentation: A Systematic Review

TLDR
This comprehensive review summarizes the findings of gut microbiota modulation in vitro as assessed by 16S rRNA gene-based technologies and elucidates the potential structure-activity relationships.

Senior Thai fecal microbiota comparison between vegetarians and non-vegetarians using PCR-DGGE and real-time PCR.

TLDR
The nonvegetarian and vegetarian subjects were found to have significant differences in the high abundance of the Bacteroides and Prevotella genera, respectively, which could provide helpful data for predicting the health of South East Asians with similar diets.

Faecal microbiota composition in vegetarians: comparison with omnivores in a cohort of young women in southern India.

TLDR
Omnivores had an increased relative abundance of Clostridium cluster XIVa bacteria and butyryl-CoA CoA-transferase gene compared with vegetarians, but the authors were unable to identify the components of the diet responsible for this difference.

Association of dietary type with fecal microbiota in vegetarians and omnivores in Slovenia

TLDR
Long-term vegetarian diet contributed to quantity and associated bacterial community shifts in fecal microbiota composition and was also associated with participants’ age, gender and body mass.

Comparative Analysis of Korean Human Gut Microbiota by Barcoded Pyrosequencing

TLDR
UPGMA cluster analysis showed that the species composition of gut microbiota was host-specific and stable over the duration of the test period, but the relative abundance of each member fluctuated, suggesting that gut microbial composition is related to internal and external characteristics of each country member such as host genetics and diet styles.

The Firmicutes/Bacteroidetes ratio of the human microbiota changes with age

TLDR
It is demonstrated that the fecal microbiota composition evolves throughout life, from early childhood to old age, and that the ratio of Firmicutes to Bacteroidetes evolves during different life stages.

Faecalibacterium prausnitzii is an anti-inflammatory commensal bacterium identified by gut microbiota analysis of Crohn disease patients

TLDR
The results suggest that counterbalancing dysbiosis using F. prausnitzii as a probiotic is a promising strategy in CD treatment and exhibits anti-inflammatory effects on cellular and TNBS colitis models, partly due to secreted metabolites able to block NF-κB activation and IL-8 production.

Impact of diet in shaping gut microbiota revealed by a comparative study in children from Europe and rural Africa

TLDR
It is hypothesized that gut microbiota coevolved with the polysaccharide-rich diet of BF individuals, allowing them to maximize energy intake from fibers while also protecting them from inflammations and noninfectious colonic diseases.

Diazotrophic bacteria associated with banana (Musa spp.).

TLDR
A large group of enterobacterial isolates that could not be clearly affiliated, most of them ascribed to group I (with characteristics of Enterobacter cloacae) were the diazotrophs most frequently found in banana.
