Core Tip
Core tip: Gut microbiome is known for major constituents of bacterial population, and their association with obesity, but microbes like viruses are majorly neglected. Our investigation on the basis of hypothesis that viruses are an important part of microbial world, and found in substantial numbers into human gut, we investigated whether viral content have any correlation with obesity in mice models. Interestingly, we found that DNA and RNA viral fecal content was significantly increased in obese mice as compared to normal. This suggests that viral population may have role to regulate host metabolism and might impact obesity prevalence via alteration of gut microbiome composition. Our findings open a new area of research to explore the role of gut virome in obesity.
