Could dysbiosis of inflammatory and anti-inflammatory gut bacteria have an implications in the development of type 2 diabetes? A pilot investigation.

Objective: Differential alterations in gut microbiota and chronic low-grade inflammation play a critical role in the development of Type 2 diabetes (T2D). Here we aimed to investigate if dysbiosis of inflammation and anti-inflammation-associated gut bacterial communities in fecal samples of individuals had any influence on T2D using a 16S rRNA gene of V3 region sequencing at Illumina MiSeq platform.

Results: Our findings showed that a higher abundance of inflammatory bacteria such as Lactobacillus ruminis, Ruminococcus gnavus, Bacteroides caccae, Butyricimonas, and Collinsella aerofaciens, and lower abundance of anti-inflammatory bacteria such as Faecalibacterium prausnitzii, and Butyrivibrio that likely play a role in the development of T2D. Our findings hint the potential of indigenous microbiota in developing diagnostic markers and therapeutic targets in T2D.
