Coliform bacteria

soybean meal present in this nutrient plate provides a source of organic nitrogen, vitamins and minerals, such as amino acids and peptides with longer chains (Siegrist, n.d.). As well, the soybean meal also has sugars, further promoting the growth of bacteria (Siegrist, n.d.). Lastly, the sodium chloride in this plate helps sustain the osmotic equilibrium. Through these extra components on the tryptic soy agar plate that are not present in the other plates, the microorganisms are in a more…

universal concern, this is because everyone must to consume food. Bacteria are everywhere, in the air, in the water, in the ground, on our food, on our skin and inside our bodies. Food scares have been numerous in the United States in the past twenty years. This fact has motivated producers and consumers alike to take an active role in the safe and quality production of their food. Foodborne illness is a significant burden globally. “Bacteria, viruses, parasites, and toxin by-products of…

Experimental trials were performed by students over a timeframe of three weeks to determine the identity of three unknown bacteria contained in broth medium stored in labeled test tubes that were randomly assigned containing: one Gram positive bacterium, one Gram-negative paracolon, and one Gram-negative coliform (Carson, 2016). The unknown sample assigned in this experiment was #19. After initially streaking the solution on clean streak plates and TSA agar, the identity was determined from a…

In everyday life, people use disinfectants, substances used to destroy viruses and microbes such as bacteria and fungi1, to clean their bathrooms. If not properly sterilized and cleaned, the bathroom can be a domain for numerous bacteria including ubiquitous Serratia Marcescens, a short, rod shaped, facultative anaerobic, opportunistic pathogen that can cause nosocomial infections such as urinary tract infections, bacteraemia, meningitis, sepsis and cerebral abscesses2. Facultative anaerobic…

believe GMO’s are bad for humans, unless you’re sick which I’m not, I see GMO’s as a bad thing. GMO’s or “genetically modified organisms” these could range from animals to plants that have been genetically altered with DNA from plants, animals, bacteria, and viruses. The American Academy of Environmental Medicine (AAEM) advises medical physician’s to recommend non-GMO diets for all patients. Doctors are saying not to wait to take actions, especially if you have little children. GMO’s hit the…

Bacteria are one-celled organisms. When looked at under a microscope, they appear to be balls, rods, or spirals. Contrary to popular belief, most bacteria are actually good for other organisms. Under 1% of bacteria on Earth cause disease, and the bacteria that do can usually be treated with antibiotics (“Bacterial Infections: Medline Plus,” par 1). The common image of bacteria is that they are all horrific organisms that cause disease. While people should most definitely wash their hands to…

lab, students will be taking the pGLO gene, which makes the protein Green Fluorescent Protein (GFP), commonly found in a species of jellyfish, which glow (N.d., p. 32). Theoretically, when the pGLO gene is inserted into the E. coli bacteria, then the E. coli bacteria will also…

How to Sterilize and Perform Intravenous Injection While acting as a medic in the apocalyptic environment that has been presented, the other medics and I will have to perform many various basic medical procedures upon the patients we receive. Seeing as the ability to properly perform these techniques is detrimental to the survival of the society, research is required to learn the safe an correct way to execute them. In this essay I will be synthesizing the information I have gathered from…

Worldwide, animals are administered sub-therapeutic doses of antibiotics so that meat industries can profit more. Because of this, a spread of resistant diseases become more likely, bacteria develop into different forms in livestock, and humans could become resistant to antibiotics due to consuming the tampered meats. Meat industries believe that bigger is better; though their demand for quicker meat production puts not only the health of the antibiotic-ingested animals at risk, but also the…
