Gut bacteria, or microbiota, are microorganisms that live in the digestive tract. Gut bacteria have been shown to play a role in weight loss, and some gut bacteria may cause weight loss. Which gut bacteria are responsible for weight loss, and how can we manipulate the gut microbiome to promote weight loss? In this article,…
A bacterial infection is the invasion and multiplication of bacteria in the body tissues causing damage and immune reactions [1]. The most common bacterial infections are: 1. What Are Bacteria? Bacteria are unicellular microorganisms, and therefore, cannot be seen by the naked eye [2]. They are also known as prokaryotes and are found everywhere around…
The gut flora (microbiota) plays an important role in human health through their metabolic function in breaking down ingested food to provide nutrients to cells and organs of the body. However, some of the products of this metabolism have been associated with carcinogenic processes, such as tumor promotion (ammonia, secondary bile acids), mutagenesis (fecapenaenes), and…
The gut flora (microbiota) plays an important role in human health through their metabolic function in breaking down ingested food to provide nutrients to cells and organs of the body. Among the metabolic products that are generated by the gut flora, proteins are critical for the function of the nervous system, such as serotonin, which…
The hallmark of Alzheimer’s disease (AD) is associated with the accumulation of “senile” plaques that are composed of amyloid-beta (Aβ) protein that surround neurons in affected regions. This accumulation results in loss of neurons in the hippocampus and cerebral cortex, leading to progressive cognitive decline such as memory defects. A connection between the brain and…
The gut flora is a heterogeneous population of micro-organisms that includes bacteria, fungi, and archaea, and that plays important role in the digestion and absorbance of food. Transplantation of fecal microbiota from younger mice (Donor) to older (Recipient) enhanced their health and lifespan (longevity). During the process of aging, the function of beneficial microbes, that…
