Staphylococcus aureus has five types of toxins that help out with its virulence. They are enterotoxin, exofoliative toxin, toxic shock syndrome toxin, leukocidin and hemolysins. Please choose 3. Explain the damage they specifically can cause and how this is beneficial to the bacteria.
Below are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)
Some S. aureus stains have a number of virulence factors including O Lipase which convey resistance to lipids and staphlokinase which clots the blood. O Lipase which digests lipids and B-lactamase which breaks the matrix between cells. O coagulase which dissolves blood clots and staphlokinase which clots the blood. coagulase which clots the blood and B-lactamase which conveys resistance to penicillin.

Write a 1-2 paragraph case study that accurately depicts the disease caused by Clostridium Botulinum. If your organism is transmitted in a specific location or under certain circumstances be sure your patient has been to those locations or engaged in those behaviors that would lead to transmission Have the appropriate timeline in terms of incubation and length of illness. Cover the important symptoms. You do not have to give all possible symptoms, just the typical one. Provide some important laboratory test results without stating the name of your microorganism. Provide the Epidemiology, Pathogenesis, Clinical Manifestations, Laboratory Tests, Treatment and Prevention.
