Mycobacterium tuberculosis
Mycobacterium tuberculosis is a nonmotile, acid-fast, obligate aerobe. The cell wall of the mycobacterium is unique in that it is composed mainly of acidic waxes, specifically mycolic acids. Mycobacterium tuberculosis is the etiologic agent of tuberculosis in humans (Kenneth Todar, 2012). In the study of Maleana Ozimek, Mycobacterium tuberculosis is unusually resistant to drying and chemicals, contributing to the ease with which it is transmitted. The bacteria are spread from person to person in tiny microscopic droplets when a tuberculosis sufferer coughs, sneezes, speaks, sings, or laughs. Only people with active tuberculosis can spread the disease to others. (National Institute of Allergy and Infectious Diseases, 2012). Slow growth rate is

In the study “Alternative vegetable nutrient source for microbial growth” by Deivanayaki M, and Anthony Iruthayaraj P, 2012, fresh raw vegetables like carrot, cabbage, tomato and pumpkin supply the needed vitamins and minerals for the five different formulations of both solid and liquid media to support the growth of Staphylococcus sp., Escherichia coli, Klebsiella sp., Salmonella sp., and fungi. All the formulations produced good growth of microbes similar to the conventional media.
In the study of Ravathie Arulanantham, Sevvel Pathmanathan, Nirmala Ravimannan and Kularajany Niranjan, 2012, they culture Escherichia coli, Bacillus sp., Klebsiella sp., Staphylococcus sp. and Pseudomonas sp.as test microorganisms using edible leguminous seeds such as green gram, black gram, soya meat and cowpea which are all rich in protein. Based on their findings, it is concluded that, Staphylococcus sp. generally grows well in all the protein formulations and Klebsiella sp. generally grows least in the protein formulations

It’s has been determined that it is contagious but will not make you sick. While everyone one in Lubbock was getting over their disease the town of Sweetwater had a fire costing $35,000 in damage. Crosbyton Texas, Lubbock
Wash hands frequently and/or use hand sanitizer. Try to cough or sneeze away from other people. You should both face away from them and physically distance yourself from them if at all possible. A sneeze cam travel up to 100 miles per hour, therefore your germs travel farther than you think when you sneeze. Because you are at your most contagious during the 2 to 5 day incubation period when you do not yet know you are sick, you should do your best to protect others from your germs at all times.
Unknown Lab Report Abiola Oyewumi March 16, 2015 Unknown #16 Abstract An experiment was conducted to determine which of the following unknown bacteria was in test tube number 16: Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, and Salmonella typhimurium. Biochemical tests were used to help identify the unknown bacteria. The Citrate test, Urease test, Triple Sugar Iron Agar test, Voges-Proskauer test, and Methyl Red test were the biochemical tests used in this experiment.
Transformation was successful in the plates where the bacteria consumed the pGLO plasmid. In the first plate that the bacterium was plated on it included the LB broth and of ampicillin antibiotic (amp), 2 colonies were present. The second plate of bacteria was grown with the presence of LB broth, ampicillin, arabinose sugar (ara), and 22 colonies were observed. But a green fluorescent glow of the colonies was only present in plate 2. Plates 3 and 4 were the control plates.
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.
This disease’s transmission would be spread through bodily fluid, sexual contact, blood and semen and even material contact too.. It can be transmitted very easily and very consolidated to contain. A perfect representation of this topic would be when a nurse had gotten the Ebola symptoms from taken care of a Ebola patient, Thomas Duncan. The nurses name is Nina Pham and she got a transfusion from a Ebola survivor and it seemed to work very well. Even though she was stricken with such a deadly disease, she was more worried about her King Charles Spaniel named Bentley, who also had a potential health risk to the community.
When given an unknown bacteria there are a multitude of steps one must go through to be able to correctly identify what bacteria was given. It is important to correctly identify the bacteria because some bacteria are more harmful than others. The gram stain is the first test that should be performed because it helps narrow down the possibilities by telling one whether the bacteria is gram positive or gram negative. After this test is performed, one shall place bacteria on/in Mannitol Salt agar, MacConkey agar, Eosin Methylene Blue agar, Urea agar, Simmon’s Citrate, Purple Beef broth with Lactose and finally Purple Beef broth with Sucrose. A streak plate should also be made up, this helps one identify the morphology of the colonies.
The disease can also be spread y kissing, sharing drinks, toothbrushes, lipsticks and
If someone is near enough to a person with the virus, it can transfer, “by coughing or sneezing or spending a lot of time near [another person]” (Transmissions).
The disease travels from person to person through air by coughing, sneezing, etcetera. (“Plague 1”) Travels from people on boats to the places they take anchor in and they may have been poisoning water and the Jews were blamed for it (Dobson 13) Jews were proclaimed to be poisoning wells with it as it spread from family to family from husband to wife. (Dobson 7)
Tuberculosis and cancer are two diseases that Sontag focuses on throughout the pages we read. These two diseases are related because they are both regarded as an ominous incurable disease. Tuberculosis was deemed so mysterious and contagious that even uttering the word could cause the person to catch the fatal disease.
The bacteria are most often found in soil, dust and manure and especially things like rusty metal, the bacteria can enter the body by openings in the body like cuts or small scrapes, although this is very rare, people can get tetanus in their body from bug bites, dental infections etc. There is a higher risk of infection for women if an infectious or contaminated tool is used during childbirth or abortion. There are a number of things that could cause a newborn baby to be infected, one example would be if the knife, razor or other tools that are used to cut the newborn baby’s umbilical cord is dirty this, this could give the baby the infection because as you know, tetanus is most commonly spread from people being cut with rusty or dirty metals. Another example would be if the hands of the person delivering the baby are not clean, this is why doctors, nurses, hospitals and their tools are always very clean, what we call
Approximately 60-90% of the Gram-positive bacterial cell wall is made up of peptidoglycan and interwoven teichoic acid, while only
