The term hygiene is deeply rooted with the concept of maintaining sound health and alertness towards cleanliness, while "hygiene hypothesis" depicts the protective role of microbial community exposure in development of early immunity and initial allergic and aesthetic reactions. The tug-of-war has now been pushed toward the literal term "hygiene" over the "hygiene hypothesis" and has continued with disinfection of all microbial loads from the related environments to avoid infections in humans. With the advancement in the microbiome studies, it became clear that humans possess warm, and significant relationships with diverse microbial community. With this opinion article, we have emphasized on the importance of hygiene hypothesis in immunological responses. We also propose the individual/targeted hygiene instead of application of unanimous hygiene hypothesis. This review also elaborates the common practices that should be employed to maintain hygiene along with the balanced microbiome. [ABSTRACT FROM AUTHOR]

The gut microbiome analysis, with specific interest on their direct impact towards the human health, is currently revolutionizing the unexplored frontiers of the pathogenesis and wellness. Although in-depth investigations of gut microbiome, 'the Black Boxes', complexities and functionalities are yet at its infancy, profound evidences are being reported for their concurrent involvement in disease etiology and its treatment. Interestingly, studies from the 'minimal murine' (Oligo-MM12), 'humanized' microbiota gnotobiotic mice models and patient samples, combined with multi-omics and cell biology approaches, have been revealing the implications of these findings in the treatment of gut dysbiosis associated diseases. Nonetheless, due to the inherent heterogeneity of the gut commensals and their unified co-existence with opportunistic pathobionts, it is utmost essential to highlight their functionalities in 'good or bad' gut in human wellness. We have specifically reviewed dietary lifestyle and infectious diseases linked with the gut bacterial consortia to delineate the ecobiotic approaches towards their treatment. This notably includes gut mucosal immunity mediated diseases such as Tuberculosis, IBD, CDI, Type 2 Diabetes, etc. Alongside of each dysbiosis, we have described the current therapeutic advancements of the pre- and probiotics derived from human microbiome studies to restore gut microbial homeostasis. With a continuous running debate on the role of microbiota in above mentioned diseases, we have collected numerous scientific evidences highlighting a previously unanticipated complex involvement of gut microbiome in the potential of human health.

Sustainable poultry practices are needed to maintain an adequate supply of poultry products to the increasing human population without compromising human wellbeing. In order to achieve the understanding of the core microbiome that assumes an imperative role in digestion, absorption, and assimilation of feed as well as restrict the growth of pathogenic strains, a proper meta-data survey is required. The dysbiosis of the core microbiome or any external infection in chickens leads to huge losses in the poultry production worldwide. Along with this, the consumption of infected meat also impacts on human health as chicken meat is a regular staple in many diets as a vital source of protein. To tackle these losses, sub-therapeutic doses of antibiotics are being used as a feed additive along with other conventional approaches including selective breeding and modulation in feed composition. Altogether, these conventional approaches have improved the yield and quality of poultry products, however, the use of antibiotics encompasses the risk of developing multi-drug resistant pathogenic strains that can be harmful to human beings. Thus, there is an urgent need to understand the chicken microbiome in order to modulate chicken gut microbiome and provide alternatives to the conventional methods. Although there is now emerging literature available on some of these important microbiome aspects, in this article, we have analysed the relevant recent developments in understanding the chicken gut microbiome including the establishment of integrated gene catalogue for chicken microbiome. We have also focussed on novel strategies for the development of a chicken microbial library that can be used to develop novel microbial consortia as novel probiotics to improve the poultry meat production without compromising human health. Thus, it can be an alternative and advanced step compared to other conventional approaches to improve the gut milieu and pathogen-mediated loss in the poultry industry. [ABSTRACT FROM AUTHOR]

A healthy gut is predominantly occupied by bacteria which play a vital role in nutrition and health. Any change in normal gut homeostasis imposes gut dysbiosis. So far, efforts have been made to mitigate the gastrointestinal symptoms using modern day probiotics. The majority of the probiotics strains used currently belong to the genera Lactobacillus, Clostridium, Bifidobacterium and Streptococcus. Recent advancements in culturomics by implementing newer techniques coupled with the use of gnotobiotic animal models provide a subtle ground to develop novel host specific probiotics therapies. In this review article, the recent advances in the development of microbe-based therapies which can now be implemented to treat a wide spectrum of diseases have been discussed. However, these probiotics are not classified as drugs and there is a lack of stringent law enforcement to protect the end users against the pseudo-probiotic products. While modern probiotics hold strong promise for the future, more rigorous regulations are needed to develop genuine probiotic products and characterize novel probiotics using the latest research and technology. This article also highlights the possibility of reducing antibiotic usage by utilizing probiotics developed using the latest concepts of syn and ecobiotics. [ABSTRACT FROM AUTHOR]

The diversity of microbes and their pervasive influence on human beings is now well established. In contrast to global efforts on microbiome research, contributions from Indian R&D organizations are rather scarce. Efforts should be made to boost the microbiome research in India to harvest the fruits of the unique microbial diversity and use it for developing a sustainable economy. [Extracted from the article]
