(7pts)The bacterium Mycobacterium leprae causes leprosy in humans.This organism localizes primarily to the skin of extremities, such as the nose, toes, and fingers, where it leads to loss of protective sensation and disfiguring lesions. Temperature is a key factor in its tissue preference; it grows fastest at cooler body sites (~30oC) and more slowly at warmer, more internal sites.

The causative microorganism for leprosy is Mycobacterium leprae, an intracellular bacterium which can grow inside of macrophages. The disease caused by this bacterium exists as a continuum with two extremes. One extreme form of the disease is called tuberculoid leprosy, which is typified by an interferon-g and TNF-a dominated delayed type hypersensitivity (DTH) cellular immune response. The second extreme is called lepromatous leprosy dominated by an IL-4, IL-5, IL-10 helper T cell immune response and high levels of serum IgG1...

A scientist wants to culture Organism A, a bacterium that is salt tolerant, penicillin resistant and turns bright purple in the presence of chemical X. You are the culture media consultant and must recommend ways that she might enrich her nutrient agar to create a selective and a differential media for Organism A. You recommend the following two “recipes”. HINT This is an imaginary bacterium. You are to design two imaginary media- do not suggest ones such a MacConkey agar....

A tuberculin skin test involves injection of a purified TB (Mycobacterium tuberculosis) antigenic protein under the skin. A positive skin test is a local swelling and redness at the site after 48 to 72 hours. (a) What cell type is responsible for this reaction? (b) Why do people who have been vaccinated with BCG (attenuated bovine tuberculosis bacterium) sometimes have a positive skin test even if they do not have active tuberculosis? Rapamycin (sirolimus, Rapamune) is a common anti-rejection drug...

You have isolated a single celled organism from an infection that you believe is a bacterium. You would like to identify if that microbe is really a bacterium and not a eukaryote. Provide ten physical differences that you would be able to use to distinguish between a prokaryote and a eukaryote. (A Table comparison would be an appropriate format for your answer.) The following table is a comparison of prokaryote and eukaryote physical structures. Physical Structure: Prokaryote Eukaryote Flagellum Size...

The bacterium Micrococcus luteus lives on mammalian skin where it feeds on amino acids and lactic acid found in sweat. Answer the following questions about carbohydrate metabolism[1] in M. luteus. M. luteus lacks any hexokinase orthologs (e.g. any enzyme catalyzing the reaction glucose + ATP ⇌ glucose-6-phosphate + ADP) as well as any phosphohexose isomerase homologs (e.g. any enzyme catalyzing the reaction glucose-6-phosphate ⇌ fructose-6-phosphate), but they express all other enzymes involved in glycolysis. Are M. luteus bacteria capable of...
