Microbes have coevolved with humans and reside in and on human body to develop a host associated structure, called “Human Microbiome” or “Human Microbiota.” These microbial counterparts account toward 10% of human body weight and outnumber human cells by approximately by tenfold and considered as commensals. Human microbiome is defined as the total genomes of microbes (constitute bacteria, bacteriophage, fungi, protozoa and viruses) that live inside or on the human body [1]. There are trillions of microbes living in/on human body plays a fundamental role in normal functioning of metabolic, physiological and immune system. Microbiota is a complex ecosystem consisting of bacteria, protozoa, viruses and fungi; all varies in number even in body parts of same individual. Human body has 10 times more bacteria than the number of human cells in our body [2]. Most of these bacteria are present in gastrointestinal tract [3] which account for approximate 70% of the total microbial load in or on human body (particular in large intestine) [4]. Humans are born sterile and start acquiring human companion to shape resilient microbiome structure. Establishment of microbiome starts with birth and matures with age. Microbial introduction and the establishment of microbiome is a random process influenced by many factor like mode of delivery, diet, sex, age, genetics, geographical location have a strong impact in shaping human microbiome structure [5–10]. These microbes are in symbiotic relationship, beside gut they are also found in mouth, respiratory tract, vagina and skin.","PeriodicalId":133564,"journal":{"name":"Role of Microbes in Human Health and Diseases","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122351534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The skin of an animal carries thousands of microbes. Some are beneficial and protect the animal while others are pathogenic and cause diseases. Some microbes have no defined roles in animals. These microbes end up in the human body through contact with the animal skin. In recent years, the human body has been studied as an ecosystem where trillions of microorganisms live as a community called microbiome. Humans need beneficial microbes like Bacillus subtilis on the skin surface to stay healthy. Many microbes need the human body to survive. Not many studies have looked into the close link between animal leather and the human microbiome. The assumption is that conventional leather processes inhibit the pathogens on skins from carrying any risk of microbial hazard to the human body. This chapter identifies endemic microbes of “animal skin microbiome” that withstand extreme acidity and alkalinity of leather manufacture and their transmission to humans. Some cause allergic reactions, skin lesion, infections or death to tannery employees with weakened immune systems. This promotes the need to look at leather product microbiome impact on human health.","PeriodicalId":133564,"journal":{"name":"Role of Microbes in Human Health and Diseases","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124651878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known to cause pulmonary infection in immunocompetent patient, but its dissemination outside the lungs has been linked to a high degree of cellular immunosuppression as seen in the advance stages of human immunodeficiency virus infection, and after chemotherapy. Despite extensive research, screening, education, and continuous efforts to try to eradicate and control the infection, tuberculosis is still one of the most prevalent infections throughout the world. Even the cases of extra pulmonary dissemination are seen to have increased. Extra pulmonary tuberculous dissemination has a very variable presentation that depends on the organ involved. The diagnosis is difficult and many times a long time passes between diagnosis and initial presentation. In this chapter, we will review how tuberculosis infection presents when the bacilli invades any tissue outside the pulmonary parenchyma, what the literature recommends for the proper work up and diagnosis, and general treatment for major organ system infection.","PeriodicalId":133564,"journal":{"name":"Role of Microbes in Human Health and Diseases","volume":"327 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133719350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a highly diverse microbial community and is essentially an open ecosystem despite being deeply embedded in the human body. The gut microbiome is continually exposed to allochthonous bacteria that primarily originates from food intake. Comprising more than 1000 bacterial species, the gut microbiota endows so many different functions—so many that can be considered as an endocrine organ of its own. In this book chapter, we summarize the importance of gut microbiota in the development and maintenance of a healthy human body. We first describe how the gut microbiota is formed during the birth of a human baby and how a healthy microflora is established overtime. We also discuss how important it is to maintain the microbiota in its homeostatic condition. A discussion is also given on how alterations in the microbiota are characteristic of many diseased conditions. Recent investigations report that reestablishing a healthy microbiota in a diseased individual using fecal microbial transplant can be used as a therapeutic approach in curing many diseases. We conclude this chapter with a detailed discussion on fecal microbial transplants.","PeriodicalId":133564,"journal":{"name":"Role of Microbes in Human Health and Diseases","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125795697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
