test. After allowing the corresponding time for each biochemical test, data was collected to determine the unknown bacteria. The broth culture in this experiment was determined as Escherichia coli. Introduction All organisms are divided into three domains; bacteria, archaea, and eukarya. The organisms making up domain Bacteria and domain Archaea are all prokaryotes. Although bacteria and archaea look the same, archaea is more closely related to eukarya (Madigan et.al 2009). The ability to adapt

requirement for this experiment is twenty-four degrees Celsius or above which is room temperature. The two types of organisms cultured are lactobacillus acidophilus and staphylococcus epidermidis. Lactobacillus acidophilus is a probiotic which is a live bacteria that is good for your health and found naturally in foods like yogurt. Staphylococcus epidermidis is a gram positive organism which is found naturally on our skin. C. Conditions Necessary to Control Microbe Growth In this experiment, microbe growth

This is done by manipulating the biochemistry of the DNA during cell division (splitting of one cell into two new cells) and DNA replication (producing two identical copies of the cell’s genetic material). …For example, … part of the DNA from Bt bacteria, [is] inserted into the DNA of corn, to produce a totally new species of corn [Bt-corn] that produces the Bt toxin as a built-in pesticide.” Pesticides are sprayed onto crops on regular intervals throughout the growing process. One of the most

Clostridium Tetani The bacterium kingdom possesses many different types of organism which are sometimes vital to our survival on this planet, but there are also thousands of other members of the bacteria kingdom which are very harmful when they are contracted by the human body. One of those organisms is Clostridium Tetani also known as Tetanus. This bacterium is a “Gram-positive, meaning it lacks an outer lipopolysaccharide membrane and possesses only a thick peptidoglycan cellular wall”. Tetanus

infection in her body before she had the leg ulcer. It is common that people carry MRSA on the skin, but it is harmless until it has contact with the body. The conditions that bacteria need to grow are warmth, oxygen and moisture. An ulcer has all 3 things that bacteria need to grow so the ulcer would have attracted the bacteria to the leg. Indarjit Singh is 6 years old and has been admitted to the Children’s ward with measles. His mother decided not to give him the MMR (measles, mumps and rubella)

the external environment (the skin, oral cavity respiratory tract, gastrointestinal tract, and the genitourinary system); these commensal microorganisms (normal microflora) such as bacteria, yeast and some virus co-evolved with their hosts, meaning they don’t cause any harm and are also beneficial. Commensal bacteria are important as they help us digest food, nutrient metabolism, tissue development as well as maintain a good mucosal immune system to prevent the colonization of bacterial pathogens

Can the Bacteria in Your Gut Explain Your Mood? The rich array of microbiota in our intestines can tell us more than you might think. By PETER ANDREY SMITHJUNE 23, 2015 Eighteen vials were rocking back and forth on a squeaky mechanical device the shape of a butcher scale, and Mark Lyte was beside himself with excitement. ‘‘We actually got some fresh yesterday — freshly frozen,’’ Lyte said to a lab technician. Each vial contained a tiny nugget of monkey feces that were collected at the Harlow

intestines would solve the problem. However, he also proposed the implanting of a snake carcass as snakes have roughly the same length and consistency of a human intestine. The doctor then realized that the snake carcass would not have the basic bacteria needed to process food in ordinary life, so that idea was scratched. So there you have it folks, I am cursed to live my entire life as a constant drunk person. If you ever see me in public, you should be prepared and hold a bucket, purse, or shoe
