a. What is the diagnosis ?
b. How is this infection acquired?
c. What therapy is appropriate?
d. Why are dogs and cats not permitted on beaches in resort areas?

8) This chemical is used to induce anti-viral responses in cells to protect the cells from viral infections.
9) This complement activation pathway is activated when complement binds to an antibody bound to antigens.
Shigella, Mycobacterium, and numerous other pathogens have developedmechanisms that prevent them from being killed by phagocytes.a. Suggest two or three factors that help them avoid destruction bythe powerful antiseptics in macrophages.b. Suggest the potential implications that these infected macrophagescan have on the development of disease.

As a precaution, you vaccinate her against tetanus. In response to the vaccine, how does her body produce antibodies against C. tetani and prevent future illness due to tetanus? A)B cells that produce an appropriate antibody undergo genomic rearrangement in order to produce other cells that secrete the same antibody. B)Every cell in her immune system produces antibodies against C. tetani. C)B cells with an appropriate antibody are stimulated to divide, producing plasma cells that make antibodies to C. tetani, and memory cells that "remember" C. tetani.

- Here are three different methods that were used to protect people from smallpox: 1. Blowing ground-up scabs into a person’s nostrils.2. Scratching fluid and puss from smallpox pustules into a person’s skin.3. Injecting a virus related to the smallpox virus. How would the immune response to these methods be the same or different from smallpox virus infection? How would each of these methods protect from infections with smallpox?arrow_forwardWhich of the following virulence factors among A-D is correctly matched with its definition or characterization? A) O Invasins: pathogen proteins that prevent opsonization of the pathogen B) O Phase variation: allows pathogen to switch between different forms of an extracellular antigen (e.g., flagellum) C) O Protein A. a microbial factor that allows for attachment, typically a surface protein or surface glycoprotein D) O Prevention of lysosome:phagosome fusion mechanism employed by an extracellular pathogen E) OM protein, Opa protein: enzymes that interfere with the functioning of antibodiesarrow_forwarda.

- Smallpox has been widely reported as a possible bioterror weapon. Given what you know about the etiology of the disease and the current state of the world’s immunity to smallpox, discuss how effective (or ineffective) a smallpox weapon might be. What kind of defense could be mounted against such an attack?arrow_forwardPart A) What barrier was breached by the pathogen? Part B) Describe how that barrier works and how it can prevent mom's pathogens from infecting the fetus. A tiny 1-kg (2.2-pound) female neonate (newborn) was born two months premature. The baby had extreme difficulty breathing and had to be intubated (a breathing tube inserted). The mother, at the time of admission, had complained of mild diarrhea and abnormal abdominal pain unrelated to her pregnancy. The infectious disease doctor who was called in to consult on the case immediately recognized the likely problem and ordered blood cultures be performed on the infant. The infant was also started on intravenous antibiotics. Two days later, the lab reported finding a Gram-positive bacillus-Listeria monocytogenes-in the infant's blood. This same organism was the cause of the mother's diarrhea. The mother had unwittingly ingested some unpasteurized cheese contaminated with this pathogen and developed listeriosis. The organism entered the…arrow_forwardYou have a suspension of fungal cells and have narrowed it down to 2 different types of fungus. You have solutions of 2 types of antibodies. 1.
