Bacteria Essay

Probiotic species Bifidobacterium animalis subsp. lactis Our large intestine is an advanced ecosystem, where thousands of bacteria proliferate. these Bateria are helpful in absorption of non digested nutrients from the food example starch, polysaccharides, sugars etc. Bifidobacteria is gram-positive, anaerobic and rod-shaped bacteria, that can be esily found in the large intestines of humans and animals (mammals). Bifidobacterium animalis Is a type of the species, which act as probiotic…

Leptospirosis is a zoonotic disease, caused by the bacteria genus Leptospira, that can cause a variety of symptoms and which, untreated, may lead to meningitis, kidney damage, or even death (“Leptospirosis”). Leptospires, bacteria of the genus Leptospira, appear as tightly coiled spirals and achieve optimal growth at 28-30°C, thriving in warm and humid regions. However, because most tropical, humid countries are also developing counties, chances of exposure are greater in those areas (Levett).…

stressed out red blood cells to create an environment where harmful malaria bacteria would not be able to thrive in. The cause was later isolated in 1956 by medical researchers as G6PD deficiency which is common in African and Mediterranean descents. G6PD is an enzyme that protects red blood cells from damage, and premature death. This means that the bodies of people with G6PD deficiency will be weaker against harmful bacteria, and with primaquine stressing the red blood cells, the body becomes…

Antimicrobial resistance is gaining momentum in health care as a major cause of concern for the implications it bears on treating patients infected with microbial pathogens. Abbreviated as AMR, Antimicrobial resistance, occurs when bacteria that cause illness can no longer be treated with antibiotics (or other prescription drugs) that previously were able to inhibit the growth of or kill off the microbial infection (Frey, 2003, pg 70). For a health care provider this means treating what was once…

A Chemical That Works Against Life Antibiotics (sometimes called antibacterials) are a strong group of medicines that are used to treat infections caused by bacteria and certain parasites. The term antibiotics comes from the Greek terms “anti” (which means “against”) and “bios” (which means “life”) While our scientific knowledge of antibiotics has only recently been developed, the practical application of antibiotics has existed for centuries. Many ancient cultures, including the ancient…

Bacteria are prokaryotic microorganisms that have no nucleus. Often times these forms of bacteria usually don’t need much to live and can reproduce rather quickly. These bacteria can cause a lot of major diseases and the only way to get around these problems is to maintain a perfect hygiene. Our hands especially, which are constantly filled with bacteria that can cause major harm to the body. Hospitals are easily considered one of the places with a lot of bacteria and infectious diseases.…

The purpose of this experiment is to determine is to be able to successfully transform Escherichia coli Bacteria, and make it ampicillin resistant when exposed to an extracellular plasmid of DNA. It involves introducing the E. coli and allowing it to adapt to the DNA of a new environment. The E. coli must be placed in a tube, into an ice bath, causing the cell to shrink. From there it is transferred to a preheated bath, where the cell is heat shocked, allowing the plasmids ' to enter the cell at…

disease caused by Legionella bacteria, and is named after a convention held in Philadelphia in which members of the American Legion attended and contracted the illness. Legionella bacteria are found naturally in fresh bodies of water, and grow in warm water. People can be exposed to the bacteria from not-properly disinfected hot tubs, air-conditioning units in large buildings, fountains, or swimming in warm bodies of water and inhaling small amounts of said water. The bacteria cannot be…

factors that speed up rancidity. Food poisoning can be caused by eating food contaminated with bacteria such as campylobacter, salmonella, listeria, shigella and Clostridium perfringens. With moisture, a food source, enough time, and suitable temperatures, bacteria will grow and multiply rapidly on foods, especially related to improper foods handling. Food which has become contaminated with harmful bacteria does not always taste bad but it looks, smells and tastes like it normally does. The…

gone through enough environmental changes to learn how to adapt quickly. As small organisms that reproduce rapidly, bacteria cells are the most abundant organisms on earth and the most important. Gram staining is used by scientists to help identify and classify bacteria due to the fact that it is difficult to discern unstained bacteria through light microscopes (1). Since bacteria are small organisms that are hard to distinguish through microscopes, the staining allows for the determination of…
