Introduction Life could not exist without microorganisms: plants depend on microbes to obtain soil and cows need microorganisms to digest cellulose. Microbes degrade waste and they live in our bodies to keep us healthy. Microorganisms are also used to make vaccines and antibiotics. However, some bacteria are known for causing diseases such as the common cold, AIDS, Herpes, and Chicken Pox. Knowing the identity of microbes is essential for knowing the causative agent of a disease in order to…

Discussion: Each test is a pertinent contribution to drawing an educated conclusion. After performing the gram staining and observing which unknown culture was gram positive, a catalase test was performed. The catalase test allows lab workers to differentiate Staphylococci and Streptococci genus. The test was performed only on the gram-positive culture. Bacteria that respire by the use of oxygen, otherwise known as aerobic respiration, produce enzyme or “catalase”. This protects the bacteria…

An unknown sample #18 was obtained on November 6, 2017. The sample came in a glass test tube with a cotton swab that contain the unknown sample. To find the identity of the unknown sample, we had to conduct several biochemical tests to eliminate and narrow down possible organisms that fit the biochemical description to accurately identify our unknown organism of interest. These biochemical tests provided insight on the physical color retention of our unknown sample, and through’s the unknown…

Literature Review The majority of the literature agrees that antibiotic resistance is a serious issue that results mainly due to the overuse and misuse of antibiotics. This issue is causing a large financial impact on the health care system. A study conducted by Rajasekar, Guest, and Bodansky (2015), analyzed the medical records of 100 patients in order to ascertain whether or not these patients actually had illnesses that could be treated with antibiotics, or if the antibiotics were misused.…

Normal flora is the colonisation of human tissues by a diverse mixture of microorganisms. This colonisation begins at birth with pioneer species, depending on physiochemical factors. The normal flora inhibits the skin, oral cavity, upper respiratory tract, gastrointestinal tract, urogenital and conjunctival membranes. They are commensal bacteria; getting shelter and nourishment from the host without causing harm (Gould, 2012). To a healthy individual, most normal flora is harmless, however some…

I. INTRODUTION The worldwide the bacterial community includes billions of microorganisms. Microbiologist and other scientists are constantly working of identifying species and classifying them by morphological, biochemical and molecular tests. This is valuable to the medical community, as some of these microorganisms are pathogens, but also to other industries such as pharmaceuticals, foods and drinks production, ecological, agriculture and biotechnology as humans have used bacteria for years…

One third of our composition of the gut microbiota resembles to our parents composition of microbiota. But after being born, the 2/3rd of our composition of our microbiota is dynamic up until the age of 3. There are several factors that affect the composition of the gut microbiota throughout our lives but it is most effective on newborns. The first factor that affects the composition of the microbiota is how the baby is delivered. (2) Vaginally delivered babies are colonized by vaginal microbes…

Gamma Proteobacteria. Because of its rod-shape, E. coli’s Order is Enterobacteriales. Escherichia coli has peritrichous flagella, meaning the flagella’s mouth is surrounded with cilia. These peritrichous flagella fit E. coli into the Family Enterobacteriaceae. Since E. coli is mainly found in the GI tract of humans and other animals, it is placed in the Genus Escherichia. The Genus Escherichia has five species, one being Escherichia coli (Moder, 2008). There have been more than 700 serotypes of…

Malabanan, Joshua Yran P. Professor Cynthia Solem English 1A 05 December 2014 How E. Coli Can Make Us Die A 4-year-old Oregon girl has died from medical complications possibly resulting from an E. coli infection contracted sometime just before Labor Day weekend, according to the girl’s uncle, who spoke with Food Safety News. Serena Profitt of Otis, OR, died Monday at Doernbecher Children’s Hospital in Portland. Her symptoms of E. coli infection first appeared around Aug. 29 with bouts of…
