M icrobiology laboratory is a branch of medical laboratory. Interested in studying infectious diseases, which is the microorganisms [1]. There are four type of microorganisms that causes infectious disease are bacteria, parasites, fungi and viruses. The microbiology laboratory is study the microorganism that cannot be seen by the eyes [2]. The microbiology laboratory is take a sample from patient to know what type of bacteria or another microorganism a causing the disease, and what the best treatment for it. The main purpose of the microbiology laboratory is work to discover the reason and causes of the diseases and treatment medical microbiology laboratory is one of important laboratory in clinical laboratory. The microbiology laboratory is very important that help to the diagnosis and pathogenesis of infectious diseases [2]. The microbiology laboratory has many section such as bacteriology, parasitology, virology and mycology [3]. Microbiology laboratory has many sections and each section do many type of test. The time of get a result of test is depend to the test, some of test finished is many hours and another may be many days. The bacteriology laboratory has two types are aerobic and anaerobic. The bacteriology laboratory is detecting which bacteria is cause the infection disease in the patient. The second section is parasitology laboratory is find the parasite, have three types of tests such as fecal (stool) examination, endoscopy and blood. Another section special in
TASK 2 Infectious diseases are the invasion of host organisms, (microbes) which can be invisible to the eyes. The microbes are also known as pathogens. A microbe infects an organism (which is known as the host of the microbe). In a human host, the microorganism causes a disease by either disrupting an important body process or by stimulating the immune system to mount a defensive reaction. The pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb, and even death.
Identification of bacteria within Unknown Culture #21 In this experiment, an unknown culture of two different types of bacteria was assigned to each person, a number of tests were performed to isolate and identify these bacterial cells. Based on knowledge from the previous experiments completed in lab, a basic understanding of each type of bacteria was used to create a flow chart that would aid the process of identifying the unknown bacteria within the culture. A gram stain that is performed initially will narrow down the types of tests certain bacteria will and will not respond to. In addition to the gram stain, some of the tests that were used include, a catalase test, an Eosin methylene blue (EMB) agar test, a bile esculin test, and a 6.5% sodium chloride (NaCl) test.
Mannitol Salt Agar (MSA) plate, MacConkey agar (MC) plate, Eosin Methylene Blue agar (EMB), and Hektoen Enteric Agar (HEA) (3). The MacConkey agar plate and the Mannitol Salt agar plate are both used in the identification of the unknown. The MC plate is a selective and differential medium. It is considered a selective medium because the bile salts and crystal violet aspect of the medium prevent the growth of gram positive bacteria (3). This medium is differential because of the lactose and neutral red.
The author starts by explaining the human microbiome and the research on it. For many years, biologists thought that the human body was able to perform all of its important functions by itself. However, in the past decade, they have found that the human body contains trillions of microorganisms that help with these important processes. In fact, they outnumber human cell 10 to one. At first, microbe research was only focused on harmful pathogens, but recently, biologists have figured out what the most common bacteria in the human body are, and have been trying to figure out the specific functions of theses microorganisms.
In this experiment, we cultivated an unknown specimen containing two microorganisms. The purpose of this experiment was to use a variety of biochemical test previously learned in the lab to identify the unknown bacteria. The identification of unknown bacteria is a major part of microbiology. Microbiologist observe samples such as blood and sputum in the laboratory for the presence of microorganisms. Identifying unknown bacteria is extremely important in clinical settings because it helps physicians find treatment for infections.
Unknown Lab Report Unknown # 25 By: Jenna Riordan March 19, 2018 Bio 2843 1. Introduction Microbiology is the study of microorganisms found in all different environments throughout Earth, from the hot thermal vents at the bottom of the ocean to the ice at the top of a mountain.

In addition, Short dogs is due to a dominant allele(S), and long hair is due to a recessive allele (s). Which of the following is the genotype of the dogs with free ears and short hair? a. ffss b. FfSs c. ffSs d. Ffss 2.
Being able to identify unknown microbes from systematic testing is what makes the field of microbiology so important, especially in infectious disease control. Using the testing procedure laid out by the microbiology field we are able to identify unknown bacteria present in our everyday lives, and along the way learn a lot about their characteristics that separate them from other types of bacteria. Being able to do this is vital in order for us to understand why microbes are present in certain places, how they are able to grow and what restricts their growth, that way they can be combatted if necessary. These techniques for determining unknowns are also important for isolating and testing infectious disease microbes in order to prevent spreading. Another important aspect of being able to identify unknown microbes is the
However, this determination is not always straightforward. Viruses have some, but not all, of the qualities of living organisms, and scientists have long argued whether or not they should be considered as living organisms. In this exercise you will determine whether specimens are non-living, living, or dead. CHARACTERISTICS OF LIFE - STATION LAB Lab Procedures: First, observe the specimens located at each station without touching it.
Exercise 14: Unknown Identification Lab Report The purpose of the study was to identify the unknown bacterium using various biochemical tests in addition to using scientific methods in determining the outcome of the hypothesis. Each biochemical test will help determine the bacteria based on specific characteristics of each organism. I was giving unknown number 232. The first procedure that needed to be done after obtaining unknown bacterial mixture was to isolate the two bacteria in a pure culture using the streak plate method described in Microbiology Laboratory Manual Eight Edition. The material used was trypticase soy agar (TSA) plate, nutrient plate, starch agar, hydrogen peroxide, iodine reagent and microscope.
Aseptic technique was initiated at the beginning of this experiment by cleaning the work surface with disinfected wipes. Personal protectives equipment was also worn. The material utilized in this experiment was: S. epidermidis culture broth, sterile cotton swab, streak plate, forceps in 70% alcohol, a lit tea light, and the three antibiotic disks (novobiocin, gentamicin, penicillin). The first step, I divided a plate into three quadrants and labelled them with the different antibiotic names. Using the lit tea light, like a bursen burner, I flamed the mouth of the S. epidermidis culture.
The effects of alcohol on Biological Membranes. Introduction In this experiment it will be analysed the damage alcohols can have on biological membranes. Membranes are made up of lipids and proteins. Membranes usually help maintain the balance in a cell as it holds all the cellular materials.
To Graduate Committee Admission of Biochemistry and Cell Biology Program of Rice University: My inclination to study biology comes to me since I was little boy. I always found amazing the capabilities of living beings and mechanisms that allow life, development and evolution of organisms. Particularly interesting were my first approaches to microbiology in early classes in high school. My fascination by biological sciences was such that it led me to win the National Biology Contest held in Cuba, my native country in 2004. This was one of my first academic achievements in my short career and allowed me to directly enter the best pre-university school in my country.
Joshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.
As each year passed, I realized how much my family members have deteriorated. Whether it was through mental health or physical health, it seemed as though someone was constantly at war with their personal health. For this reason, I want to educate myself on what causes people to get sick and how it affects them internally. As a result, I chose Microbiology as my major. The knowledge I gain about microbes and their effects on human beings will allow me to undergo the research needed to help defend the population against them.
