The Challenge of Antibiotic Resistance: Has our use of Antibiotics Caused more Problems than it has solved?

Antibiotics are medicines which have bactericidal or bacteriostatic properties and used in treatment or prevention of microbial diseases (NPS 2012). Antibiotics a have been in existence for a long time and were initially known as antibiosis which meant against life, and by Jean Paul Vuillemin first used this term. He used the word to describe the properties which were exhibited by the early antibacterial drugs. In 1877 Antibiosis was first described by Louis Pasteur and Robert Koch when they observed the inhibition of growth of Bacillus anthracis by an airborne bacillus. In 1928 penicillin was identified by Alexander Fleming. ...

Question 1

Compare and contrast the concept of metagenome and microbiome. The microbiome is a term used in describing the entire habitat; it includes microorganisms and their genomes and the surrounding environmental conditions. The microbiome is defined based on the biotic and abiotic factors in a specified environment. On the other hand, metagnome can be defined as a collection of genes and genomes normally from the members of the microbiota. Microbiota is an ecological community that includes symbiotic and pathogenic microorganisms that share our body space. The analysis of microbiome can be done for a large number of samples and can ...

Introduction

Trillions of microbes constitute the “Metagenome” of the human gut. This is the organ called microbiome, which is highly essential, and offers the host benefits such as metabolic abilities, pathogen protection, immune system enhancement, and GI tract developmental modulations (De Fillipo, et al.). In their study, three questions regarding the evolution of the human microbiota have been raised. They are: (1) how does the partitioning of bacterial diversity between and within two populations studied? (2) Does there exist a correlation between the diet and bacterial diversity?; and (3) considering the varied geography and hygienic conditions, what is the bacterial ...

Metabolic Changes

Connections between microorganisms in a person’s gut and the onset of obesity among other metabolic conditions are getting clearer with advanced research work. However, owing to the complexity of the microbiome, the connections are just beginning to be appreciated. However, proportional research work involving mice suggests that there is an influence of gut microbiota on the metabolism of a host. Extensive gut microbiota modulation of host systemic metabolic pathways including SCFAs, tryptophan, and tyrosine metabolism has been shown by metabolomics studies. Metabolic regulation is one of the functions of the metabolites in the gut due to its nutrient-rich ...

Introduction

Recently, worldwide obesity prevalence has been raised rapidly and nearly doubled between 1980 and 2014, however in 2014 more than a half a billion of adult (18 years and older) were obese (11% men and 15% women) (WHO, 2014). Obesity and overweight are defined as excess body fat accumulation that leads to health risks and comorbidities. Adult weight can be classified based on the Body Mass Index. Hence, an individual having a BMI equal to or more than 25 is regarded as being overweight, while a person with a BMI equal to or more than 30 is considered obese ( ...

Define the term probiotic. (Make sure you include the three components of this definition and use your own words—DO NOT copy the statement from the slide).

Probiotic is a term used to define microorganisms that are believed to have health benefits to humans when consumed.

When did the NIH human microbiome project begin and what were its two major objectives? NIH human microbiome project began in the year 2005. Its two major objectives are to identify microbes present human body and identify their role in human health and disease

Which different mechanisms were suggested through which microbiota may contribute to colorectal cancer?

Microbiome can contribute to colorectal cancer by the production of toxic and genotoxic bacterial metabolites that can lead to mutations by binding specific cell surface receptors and affect ...

Lab report

Abstract The contemporary microbiology world has witnessed a gradual interest in identifying the types of microbes that are resident in the human body more so due to plausible health benefits they may bring and because of their possible detrimental effects. In this regard, fear of the pathogenic consequences of microorganism in the body has pioneered the advent of hand sanitizers aimed at checking this effect. As a standard procedure in microbiology especially in laboratory experiments, sanitizers are used in eliminating microbes from the surface of the hand. The conducted experiment in this write-up thus aims to analyze the presence ...
