genetic transformation that was used in lab and mainly used due to the single celled nature of bacteria. In this lab‚ the engineered pGLO plasmid is integrated into E. Coli bacteria‚ and adds the genes which code for the proteins GFP in the modified bacteria’s genome (Hanahan‚ Studies on transformation of Escherichia coli with plasmids‚ 1983). To see the reaction of this plasmid on the cells‚ bacteria treated with the plasmid were grown on two separate agar plates containing LB nutrient broth and

is part of the tetracycline class of antibiotics that fights bacterial infections‚ like urinary tract infections. This drug is also known as a broad-spectrum antibiotic that treat all types of bacterial infections (Drugs.com‚ 2015). Malaria has a bacteria agent called Plasmodium falciparum that causes an individual to experience fevers and high chills. Doxycycline would be able to treat malaria because it is an antibiotic. Doxycycline is taken by mouth in the form of 50 mg‚ 75mg‚ or 100 mg capsules

diseases are caused by agents such as bacteria‚ parasites‚ protozoa‚ fungus and virus. Bacteria exist on every surface including in the air and below sea level. Most bacteria are harmless but others are harmful to our body and can do bad to your health and internal organs‚ kidneys and the heart. Bacteria can invade into the body via the mouth‚ sexual organs‚ nose‚ eyes or any cuts which need to be cleaned and dressed. Bacteria can enter the body if food is full of bacteria or it isn’t cooked properly‚ this

Salmonella 1) What is the infectious agent (Pathogen) that causes this infectious disease? The infectious agent (pathogen) that causes salmonella is called salmonella enteriditis. The bacteria is larger than a virus; but‚ is visible to the eye with the microscope. It is rod-shaped‚ gram negative‚ non-motile bacteria that does not form spores. It infects the cell‚ multiplies within it; then‚ bursts the cell. Special effector protein factors are required for salmonella intestinal invasion and the induction

bacilli‚ in red)‚ the most common Gram stain reference bacteria Gram staining (or Gram’s method) is a method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative). The name comes from its inventor‚ Hans Christian Gram. Gram staining differentiates bacteria by the chemical and physical properties of their cell walls by detecting peptidoglycan‚ which is present in a thick layer in Gram-positive bacteria.[1] A Gram-positive results in a purple-blue color while

Please answer the following questions. Your answer for each question should be a minimum of 150 words (half page). Please number your answers with the number of the question you are answering. 1. Koch was the first scientist to prove that bacteria actually cause disease. He scientifically demonstrated that a disease is caused by a particular organism. He created four general guidelines to aid in identification of disease causing pathogens. These guidelines developed from his work with purified

During the 1700s‚ microscopes were used to further explore on the microbial world‚ and by the late 1800s‚ the light microscope had been developed. “The electron microscope was developed in the 1940s‚ thus making the viruses and the smallest bacteria (for example‚ Rickettsiae and Chlamydia) visible” (Introduction to Microscopes‚ n.d.).

Staphylococcus aureus? Vancomycin 5. Why has antibiotic resistance happened? Certain bacteria resist the effects of the antibiotics (are not killed) and multiply and spread. 6. Explain why the increase of antibiotic resistance is an outcome of evolution. Because some bacteria are naturally resistant to specific antibiotics they are not killed off by these drugs‚ and reproduce‚ creating new populations of bacteria that are resistant. Over

Some of the major diseases include Bacterial Keratitis‚ Fungal Keratitis‚ Acanthamoeba Keratitis‚ and Herpes Simplex Keratitis. Bacteria‚ fungi‚ amoebae‚ and viruses are the prime cause for these diseases. These microorganisms settle in the cornea‚ grow‚ and feed on the cornea. This process causes a corneal ulceration. Contact lenses are the leading way these microorganisms enter

another class of organisms called eukaryotes. Prokaryotes and Eukaryotes are similar in their chemical composition and chemical reactions. Prokaryotes have peptidoglycan in the cell wall. Prokaryotes are Bacteria that are unicellular. Most Bacteria multiply by binary fission. There are three kinds of bacteria shapes: coccus‚ bacillus and spiral.
