Answer: Triatoma Bloom’s Rank: Knowledge Section: Protozoan and Helminthic Cardiovascular and Systemic Diseases 21.4 Essay Questions 1) Explain the difference between bacteremia and septicemia, and describe some of the factors that can lead to septicemia Answer: Septicemia is a microbial infection of the blood that causes disease Although the terms bacteremia and septicemia are sometimes used interchangeably, bacteremia technically refers to septicemia caused by bacteria in the bloodstream The signs and symptoms of bacteremia and septicemia are essentially the same, and both can lead to adverse consequences such as toxemia, lymphangitis, or septic shock To be able to cause these problems, the bacteria involved in septicemia may possess capsules, have the ability to capture iron from the host’s tissues, and/or release a variety of endotoxins that ultimately damage host cells and tissues Bloom’s Rank: Comprehension Section: Bacterial Cardiovascular and Systemic Diseases 2) Compare and contrast bubonic and pneumonic plague Answer: Both bubonic and pneumonic plague are caused by Yersinia pestis and are transmitted by fleas that migrate between animal hosts and humans However, pneumonic plague is generally much more serious than bubonic plague, develops more rapidly, and is more often fatal than bubonic plague In addition, pneumonic plague can occur when Yersinia pestis is inhaled, so it can be transmitted from person to person Bubonic plague is transmitted only by infected fleas Treatment and prevention of both diseases are similar: plague is easily treated by common antibiotics such as tetracycline, and prevention involves rodent and flea control, as well as good personal hygiene Bloom’s Rank: Analysis Section: Bacterial Cardiovascular and Systemic Diseases 3) List and describe the three stages of malaria, paying attention to the various forms of the protozoan parasite present in each stage of the disease http://getbooksolutions.com Answer: Two of the three stages of malaria occur in a human, and the third stage occurs in mosquitoes The human stages begin with the exoerythrocytic cycle, when mosquitoes inject sporozoites into the bloodstream These sporozoites reproduce in the liver to form merozoites, which are released into the blood Merozoites then penetrate red blood cells and launch the second human stage, which is the erythrocytic cycle The merozoites become trophozoites inside red blood cells, and these trophozoites can, in turn, reproduce to become more merozoites, which spontaneously lyse the erythrocytes, causing the characteristic cycles of fever and chills associated with malaria Other merozoites develop into gametocytes, which can be ingested by the female Anopheles mosquito to launch the third cycle, the sporogonic cycle These gametocytes go through a process of sexual reproduction inside the mosquito, eventually resulting in the formation of sporozoites once again These sporozoites migrate to the mosquito’s salivary glands, and the malaria cycle begins all over again Bloom’s Rank: Comprehension Section: Protozoan and Helminthic Cardiovascular and Systemic Diseases 4) Compare and contrast dengue hemorrhagic fever and Ebola hemorrhagic fever Discuss both the pathogens and the pathology Answer: Both diseases are caused by RNA viruses Both start with fever, headache and muscle pain, then a rash develops, followed by bleeding There is no specific treatment for either disease and no vaccines are available to prevent them Dengue hemorrhagic fever is caused by a member of the Flaviviridae, a +ssRNA virus with an icosahedral capsid It is transmitted by Aedes mosquitoes A first infection with dengue virus does not lead to the hemorrhagic disease, but it is subsequent infection that produces the hemorrhagic disease Memory T cells produced in response to the first infection are activated upon subsequent infection and release inflammatory cytokines that trigger a hyperimmune response that results in damage to blood vessels, internal bleeding, and may progress to shock from excessive blood loss Ebola viruses are filamentous —ssRNA Filoviridae whose natural hosts are thought to be bats Humans become infected when handling an infected animal, after which the virus can be transmitted from person to person by unprotected contact with blood and other bodily fluids Ebola virus infection initially triggers excessive clotting which results in depletion of clotting factors, which in turn leads to extensive internal hemorrhaging Death results from massive shock and kidney failure http://getbooksolutions.com Bloom’s Rank: Analysis Section: Viral Cardiovascular and Systemic Diseases 5) How does the age of the infected individual play a role in the development of Epstein-Barr virus (HHV-4) infections such as infectious mononucleosis? Answer: The symptoms of most Epstein-Barr infections result from a “war” between the cellular and humoral divisions of the immune system B cells are infected by Epstein-Barr virus, and then cytotoxic T cells try to kill the infected B cells The younger an infected individual is, the less mature his or her cellular immune system is, and the less effective it will be in causing symptoms during the “war.” In fact, in young children, Epstein-Barr virus infections are usually asymptomatic The later in life an individual is infected with Epstein-Barr virus, the more vigorous the cellular immune system is, and the more problematic and symptomatic the infection becomes On the other hand, however, a vigorous cellular immune response also means that the infected B cells may be completely eradicated from the body, resulting in no discernible disease in many individuals Bloom’s Rank: Comprehension Section: Viral Cardiovascular and Systemic Diseases
