In this lab project, the microbiology students were given 2 unknown bacteria in a mixed broth each broth being numbered. The goal of this project is to determine the species of bacteria in the broth. They had to separate and isolate the bacteria from the mixed broth and ran numerous tests to identify the unknown bacteria. The significance of identifying an unknown bacteria is in a clinical setting. Determining the exact bacteria in order to prescribe the right treatment for the patient. This project is significant for a microbiology students because it gives necessary skills to them for future careers relating to clinical and research work.
The purpose of this laboratory is to learn about cultural, morphological, and biochemical characteristics that are used in identifying bacterial isolates. Besides identifying the unknown culture, students also gain an understanding of the process of identification and the techniques and theory behind the process. Experiments such as gram stain, negative stain, endospore and other important tests in identifying unknown bacteria are performed. Various chemical tests were done and the results were carefully determined to identify the unknown bacteria. First session of lab started of by the selection of an unknown bacterium then inoculations of 2 tryptic soy gar (TSA) slants, 1 nutrient broth (TSB), 1 nutrient gelatin deep, 1 motility
Proteus mirabilis is part of the normal flora of the gastrointestinal tract, and as a result the bacteria enters the urinary tract or infects medical equipment by the fecal route. Consequently, prevention includes good sanitation and hygiene, including proper sterilization of medical equipment. It is also suggested that patients not requiring catherization should not receive catherization, despite its convenience for the caretaker.

Escherichia coli (E. coli) is a member of the Enterobacteriaceae family of organisms. It is a non-spore forming, facultative anaerobic, gram negative rod capable of growing on a variety of media and, similar to other members of the Enterobacteriaceae family, contains the enterobacterial common antigen. Most E. coli are part of the normal flora of the human gastrointestinal tract, however some strains are pathogenic and capable of causing clinical disease. Epidemiologic classification of E. coli is based on the expression of certain surface antigens. The three of greatest importance are the somatic O polysaccharide (part of the lipopolysaccharide or Gram negative endotoxin), the K antigens (part of the capsule), and the H antigens (flagellin proteins). The bacteria regulate the expression of these antigens through antigenic phase variation. This process allows the organism to selectively express or not express the antigens, which aids in protection from antibody-mediated cell death. Enterohemorrhagic E. coli (EHEC) are strains that produce exotoxins (particularly verotoxins) that result in hemorrhage of the intestinal mucosa. There are several serotypes of EHEC; the most clinically significant is O157:H7.
A Prokaryote is a single cell organisms that does not have a nucleus, which is divided into two major groups: archaeabacteria and bacteria. Prokaryotes are usually found in three common structures, such as bacillus is rod shaped, crocus is spherical-shaped, and spirillum is long shape. Although there are prokaryotes that are responsible for diseases there are also good types of bacteria that we need. Prokaryotes provide essential services to biological systems for instance food and agriculture.
A prokaryote is a basic unicellular cell typically chracterized by having no defined nucleus. Examples of prokaryotes are typically given as orgamins that belong to the Bacteria and Archaea domains (Campbell 13). Furthermore, prokaryotes are very similar to eukaryotes except for the fact that they don't have a nucleous but a nucleoid and that prokaryotes are smaller than eukaryotes (Campbell 98). By the definition of a prokaryote and process of elimination it is easy to find the correct answer which is D.
Mycobacterium tuberculosis (M. tuberculosis) is the bacterium that causes the disease tuberculosis (TB). A distinctive characteristic of the genus Mycobacteria is the presence of a thick lipid-rich cell wall and resistance to the decolourization step of the gram stain (being acid-fast). The acid-fast characteristic of the M. tuberculosis is the result of a waxy, lipid-rich cell wall. The cell envelope of the tubercle bacilli contains a layer beyond the peptidoglycan which is exceptionally rich in lipids, glycolipids and polysaccharides. The bacterium is gram positive bacillus which is an obligate aerobe, is non-motile, a non-endospore forming and is non-capsulated. The microscopic appearance of M. tuberculosis is seen as straight, slightly curved rods approximately 3 x 0.3µm in size. In liquid culture media, the bacteria usually grow as twisted rope-like pellets known as ‘serpentine cords’. M. tuberculosis is capable of growing on a wide range of enriched culture media such as Lowenstein-Jensen medium or Middlebrook medium. The optimum growth temperature of the pathogenic organsim is 35-37°C and unlike most other mycobacteria, it cannot grow at a temperature of 25°C or 41°C. M. tuberculosis is an airborne pathogen that is transmitted from person to person, usually infecting the respiratory tract through inhalation (Greenwood, et al., 2012).
Microbiology is the study of microscopic organisms such as virus, Protista and bacteria. It’s important to know and to identify what kind of bacteria and how we can treat it since is found everywhere in society. Also to know what kind of bacteria it is by the performing different biochemical test and be able to differentiate the bacteria. This is use in the medial field where is important to know what kind of bacteria there dealing with and know how to treat it.
This report details the steps taken and processes used to discover the identity of the unknown organism given on Tuesday, November 28th, 2017. With all of the knowledge and skills gained over the semester, in class and in lab, unknown organism 6C was able to be positively identified. The objective of these labs was to successfully utilize the tests and procedures taught during the course to correctly identify the organism and to be able to explain the reasoning behind the tests used and results found.
The morphology was viewed under microscope 1000x magnification using oil immersion. The microorganism has rod shape and purple colouring at the end of the Gram stain procedure. This implies that the bacteria had only one cell layer, which absorbed the crystal violet stain. Therefore, the microorganism is gram positive, and based on the morphology, the microorganism is Bacillus cereus (Brooks et al. 2013).b. Describe two ways the food(s) could have become contaminated. Food gets contaminated in several ways. Notably, all hands look clean but may still harbour bacteria. Uncovered coughs as well as sneezes may cause the spread of pathogens. In most cases, food borne pathogens
Bacterial fossils have been discovered that date back 3.5 billion years ago. There are over 5,000 different species of bacteria known, many of which are harmful or pathogenic (i.e. can cause disease) and some of which are beneficial and can have many uses, for example, the bacterial species Lactobacillus is used in the production of cheese and yoghurt. The bacteria Bifidobacterium adolescentis is used for yoghurt making and Brevibacterium aurantiacum is used for cheese making. Also yeast is used in the production of beers and alcohols like wine and it also plays a role in bread rising. As well as bacteria being used for food production there are also many types of bacteria used in medicine production with nearly a different bacteria used for each different disease contractible in humans, for example the bacteria Moraxella lacunta is used to produce medicine for conjunctivitis and Klebsiellapneumoniae would be used to produce medicine for pneumonia.
Abstract: How do different minerals found on other planets, affect the growth of bacteria. In this experiment, I will study the effect that extraterrestrial minerals have on the growth of E. Coli bacteria. To do this, I will prepare growth media for E. Coli, supplemented with increasing concentrations of minerals and chemical compounds found on the surface of the Moon, Mars and Vesta. Bacteria will be grown in liquid media or on petri dishes and their growth will be determined by the density of E. Coli in liquid media or by the number and size of colonies of E. Coli in petri dishes.
Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule. The capsule prevents the white blood cells and antibodies from destroying the invading bacterium. Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not cause disease. They release digestive enzymes onto the organic matter. The enzymes breakdown the large food molecules into smaller molecules, which are absorbed by the bacterial cells. Parasites live on or in living organisms, and may cause disease. A few types of bacteria are Autotrophic, they can synthesize the organic nutrients they require from inorganic substances. Autotrophic bacteria are either photosynthetic or Chemosynthetic. The photosynthetic bacteria contain chlorophyll that are different from the plant chlorophyll. In bacterial photosynthesis, hydrogen is obtained by the splitting of compounds other than water.
Knowledge is power when discussing the classes you have taken in college and how it affects your everyday life. Microbiology is one of those important classes where although for a majority of majors you do not have to take it and therefore will not learn the information discussed in it, other majors such as biology and nursing require you to take it. They will require you to take it because you will encounter some of the information being taught in it in the work field. As a nurse practitioner I have worked in the field with many patients who were diagnosed with Leprosy, Escherichia coli, Salmonella and other bacterial diseases. All of these diseases that I have encountered in patients were ones I was familiar with due to learning about them as a student in microbiology at CSUB. My children plan on
