Bifidobacterium Research Paper

If you have had recurrent infections and taken antibiotics repeatedly to treat them, you may need to repair your gut. Your gut contains around 70 percent of the immune cells active in your body at any given time, and gut flora play a role in your immune function. Antibiotics kill not only bad bacteria, but also good ones. Probiotics can help your gut recover from the abuse so your immune function can recover from having taken

A healthy adult has over 1000 species of bacteria residing in the gut (1). There is great diversity in genera of these bacteria, however the most

The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible

More than a century ago the notion of microbiota working as a regulator for health and disease was already in use. They realized that consuming large amounts of fermented milk helped with their longevity. This began the foundation of probiotics. However, the oral probiotics that are used today are at a lower amount than what is contained in the colon. After cycling through the digestive system it is

After the multitude of tests performed, it was determined that the bacterial unknown was Staphylococcus aureus. The gram stain slide was positive. The morphology and arrangement was grape like cocci clusters. On the glucose fermentation test the bacterial unknown tested positive for acid and negative for gas. The oxidase test was negative. The bacterial unknown tested positive for catalase. In the litmus milk medium a K or alkaline reaction was observed. It tested negative for urea hydrolysis. The bacterial unknown tested positive for nitrite. On the Kigler 's iron agar media it tested negative for gas, positive for glucose, positive for lactose, and negative for hydrogen sulfide. On the SIM medium media it tested negative for indole, negative for hydrogen sulfide, and negative for motility. The bacterial unknown tested negative for methyl red. It tested negative for Voges-Proskauer. It tested negative for citrate. It tested

Gut microbiome is one of the densest, most dynamic, and complex microorganism populations located in the body (Costa et al., 2012). Gut microbes act against transient pathogens, aid in digestion and absorption, stimulate the immune system, and support enteroctyes (Suchodoiski et al., 2012). Gut microbiome population differs between species, individuals, and organs (Fraga et al., 2011). It is noted that there are one billion microbes from one drop of cecal fluid, consisting of anaerobic microorganisms such as bacteria, fungi, protozoa, and archae (Fraga et al., 2012). If these microbes are changed, this could result in gastrointestinal disease and even death. Clostridium perfringens, Clostridium difficle, Escherichia coli general and K-12, and Streptococcus bovis/equinus complex (SBEC) are common bacteria found in the microbiome of the hindgut. These strains are considered opportunistic bacteria, and if the immune system becomes compromised by changes to the hindgut microbiome, this will trigger proliferation of harmful and opportunistic bacteria that can cause numerous gastrointestinal

The good gut microbes are a powerful line of defense against pathogens and germs and also prevent the overgrowth of harmful microbes such as bacteria, yeasts and parasites, making healthy bacteria vital for a strong immune system.

In 1953, Kollath introduced the term ‘probiotic’. Etymologically, the term ‘probiotic’ is originated from the hybridization of Greek words ‘προ’ and ‘βιοτος’, which brough the meaning of ‘for life’. In 1953, the term ‘probiotic’ was introduced by Kollath as “organic and inorganic supplements necessary to restore health to patients suffering a form of malnutrition resulting from eating too much highly refined food” (Hamilton-Miller et al., 2003). The probiotic word has evolved throughout the years. As indicated by the World Health Organization (WHO), probiotics are characterized as "live microorganisms that able to provide advantage to the host when consume in adequate amount (World Health Organization [WHO], 2001). Probiotics also classified

Escherichia coli is a Gram-negative rod that was tested on ten different biochemical testing procedures. The Escherichia coli culture on the MacConkey agar had growth and experienced fermenting of lactose (color change to yellow). This is an expected result because this agar only grows Gram-negative bacteria so it is a selective media. The bile salts and crystal violet are the agents that make the agar select against Gram- positive species. The pink tint is probably from the precipitation of bile salts. The Bacillus subtillis is a Gram-positive bacterium so it was not supposed to show growth or fermentation, but it showed growth without a color change (no lactose fermentation). This was due to the over streaking of maybe Escherichia coli or Enterococcus durans, which are Gram-negative species. Staphylococcus epidermis had a growth along with a yellow to orange color change. Media too was clear.

A healthy diet will in turn lead to a healthy immune system. Probiotics are used to boost and improve the body’s immune system. This will help in increasing the body’s resistance to flu and cold.

Probiotics are friendly, live bacteria that help maintain a natural balance of organisms in the intestines. Normally, the intestines have about 400 types of probiotic bacteria that serve to reduce harmful bacteria and keep the digestive system healthy. Each child (and adult) has trillions of different microbes living in him, and no two kids have the same mix of bacteria. Two of the most common categories of beneficial bacteria that naturally occur in our body are called Lactobacillus and Bifidobacterium. Whatever the benefit, it's important to note that probiotics' infection-fighting effects are only temporary. This is because the probiotics don't build up in your child's gastrointestinal system.

Bifidobacterium bifidum is a gram positive bacteria that is anaerobic, non-spore forming, and non-motile; it is commonly found in the intestinal and vaginal mucosa of humans and animals as a part of their natural flora (3). It has also been found in human and animal feces, and beef and pork meat (2). In recent years, it has experienced a surge in popularity by not only the medical but also science community because of its abundance in natural flora. Bifidobacterium bifidum is a probiotic that has a symbiotic bacteria-host relationship by playing a beneficial role in the lower gastrointestinal tract by maintaining microbial balance by “inhibiting the growth of potential

The research article, The intestinal microbiota: its role in health and disease, explores the importance and impact of microbiota for health and disease. Additionally,

Probiotics are ingestable microorganisms which gives the consumer a beneficial effect. First coined by the late eli Metchnikoff probiotics are described to be microorganisms which are ingested in small amount to increase the diversity of both flora and fauna inside the human body this reaction in turn affects the adaptation abilities for the human body to react to different surroundings, digest different things, or just improve the antibody or the mechanism that already exists in the human body.

Introduction: Through the conduction of numerous experiments, the identity of two bacterial isolates was determined. The tested specimen was an unknown sample of a mixed culture of two different species of bacteria. The first step that was taken was obtaining a pure culture of each species of bacteria by isolating one species from the other. Once isolation was complete, the isolated cultures were tested using procedures that had been performed during previous lab sessions. A gram stain was performed on the two isolates. The isolate which had tested gram negative was then tested for the presence of cytochrome C and lactose fermentation. For the gram positive isolate, cell shape was determined and a catalase test was performed.
