Question
Chapter 20, Problem 5CTQ
Summary Introduction
To determine:
The characteristics of the pathogens that make them suitable candidate for mass infection with high mortality.
Concept introduction:
Bioterrorism or bioweapon is a kind of terrorism that is characterized by the intentional release of some biological agent such as viruses, bacteria or other kinds of microbes which results in wide illness or death. The biological agent may be modified genetically to spread at the faster rate and to resist the effect of the medicine.

Students have asked these similar questions
Please discuss how pathogens are so easily spread around the world in 2021? Why is a society or planet like ours
especially susceptible to the rapid dissemination of pathogens? What are the mechanisms that move the
pathogens?
I don't know how to fill in this table. I submitted this question yesterday but the answer did not match up with the answer bank. These are the options to fill in the table - true pathogen, secondary infection, portal of exit, syndrome, portal of entry, oppunistic infection, opportunistic pathogen, morbidity, health care associated infection, virulence factor, pathogenicity, toxemia
Which of the following is NOT true of bacterial exotoxins?
1. Important in the pathogenesis of many human diseases
2. Their toxic effect can be systemic, affecting cells distant from the primary site of infection
3. None of the other four answers (All are true of bacterial exotoxins)
4. Different exotoxins may affect different types of cells (e.g., nerves, gastrointestinal mucosa)
5. Some exotoxins have two components, A (active) and B (binding)

- For each of the following: Cyanobacteria, Coronavirus, Chytrids, Ciliates, and Chronic wasting disease. Explain with details how does the pathogen invades our tissues and body after transmission. You need to include any receptors, steps etc. in its life cycle and/or the type of replication or reproduction it exhibits and how and where it exits the cells, tissues, or body. This section can also include how it spreads through the body if that is relevant.arrow_forwardAn outbreak of a vector borne disease along a river system in centrla Uganda has been identified, triggering a national alert. Patients present with complex neurological symptoms and flagellated parasites have been isolated from local animals. Based on the above information, what pathogen do you suspect might be the cause? And why? To control the outbreak, what treatments and interventions would be the most effective?arrow_forwardWhich of the following pathogens is the LEAST virulent? 1.

- Part 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_forwardC. bot and C. tetani are considered true pathogens while C. dificile is considered an opportunist.

- From an epidemiological perspective, why are most arthropod-borne viral diseases hard to control?arrow_forwardEvery employee, nurses, doctors and others who are in direct contact with any patients hospitals or in doctors chambers must adhere to infection control policies and procedures.

- All of the following are true of Lyme disease excepta) it is caused by a spirochete.b) it is transmitted by certain species of ticks.c) it occurs only in the region around Lyme, Connecticut.d) most cases get a rash that looks like a target.e) it can cause heart and nervous system damage.arrow_forwardWrite 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.arrow_forwardSelect all of the following that applies to the tradeoff between transmission and virulence that applies to many diseases. a) The tradeoff between transmission and virulence means that diseases always evolve to become more virulent. b) If greater virulence limits transmission, that disease will likely evolve to become less virulent than it could be. c) While making more copies of itself can increase the likelihood of transmission occurring, too much replication of the disease can make the host so sick it won't leave the house and spread the disease. d) A strain of a disease that replicates enough to be transmitted, but not so much that the host gets too sick to move, will be favored by natural selection over strains that either make the host too sick or do not replicate enough to be transmitted. e) If a disease can spread without making its host sick (e.g. when the host is asymptomatic), then the tradeoff between transmission and virulence…arrow_forward
