Textbook Question
Chapter 1, Problem 1VC

The table below shows the symptoms of some diseases that are caused by bacteria.
Disease
Symptoms
vomiting, abdominal pain, coughing,
muscular weakness, visual disturbance
botulism
inflammation of lungs, fever,
shortness of breath, fluid in lungs
pneumonia
typhoid fever
red rashes, high fever, intestinal bleeding
tetanus
uncontrolled contractions of voluntary muscles
Which two diseases listed in the table affect the digestive system? Be sure to support your reasoning with evidence from the table. Please write in complete sentences.
What is the best explanation for why a bacteriostatic treatment might be chosen over a bacteriocidal treatment? Bacteriostatic treatments will eliminate all bacteria while bacteriocidal treatments will only eliminate a portion of the bacteria. Bacteriostatic treatments typically have lower toxicity to the host when compared to bacteriocidal treatments. Bacteriostatic treatments will prevent all bacterial growth, while bacteriocidal treatments will permit some bacterial growth. Bacteriostatic treatments are typically more costly than bacteriocidal treatments.
For most folks, their knowledge of the importance of microbes is limited to just those microbes that cause sickness. However, you know better! Which of the following
describes a true critical feature of microbe biology illustrating their importance?
they are used in the food and beverage production industry.
some produce oxygen.
microbes are very small, and make up a very small portion of the Earth's biomass.
they are important food source for aquatic life
they are critical for the process of decay.
some can fix atmospheric nitrogen which is important for plant growth.
they influence our neurobiology and are critical components of ruminant animal digestive systems.

- Researchers are designing several experiments to test the ability of Salmonella bacteria to develop antibiotic resistance. A culture of Salmonella bacteria is exposed to the same concentrations (200 mg/L) of an antibiotic for four days. The table shows the number of isolated resistant bacteria over a four-day period. Which of the following statements best explains these results? Day Number of Resistant Bacteria in the Culture 1 5 2 59 3 677 4 32,456 The bacteria were not affected by the antibiotic. After being exposed to the antibiotic, the bacteria altered the antibiotic. A new species of bacteria emerged after the antibiotics were introduced. Random mutations led some bacteria to be resistant and, over time, they increased in the population.arrow_forwardBacteria have three major methods of resisting antibiotics. They may lack (or modify) the feature that the antibiotic targets, so that the drug has little or no effect. The may have an enzyme that helps them break down and inactivate the antibiotic. They may have efflux pumps that remove the drug from the cell. Which method of resistance are Gram-negatives particularly famous for? Group of answer choices target modification enzymatic breakdown horizontal transfer efflux pumpsarrow_forwardImagine you are an astronaut and you are the first person to walk on Mars. You make the surprising discovery that there are "bacteria-like organisms" on Mars. Which of the following do not need to be true for you to consider these "bacteria-like organisms" as living? They must be able to reproduce. They must be able to respond to their environment. They must be able to transform energy. They must be able to move.arrow_forward
- A recent study found that 480 Streptomyces strains freshly isolated from the soil are resistant to at least six different antibiotics. In fact, some isolates are resistant to 20 different antibiotic drugs.Why do you think these bacteria (which are neither pathogenic nor exposed to human use of antibiotics) are resistant to so many drugs? What might be the implications for human bacterial pathogens?arrow_forwardBacteria that can survive in extreme environments are called: a-Anaerobes b-Saprophytes c-Aerobes d-Archaebacteriaarrow_forwardIf all prokaryotes on Earth suddenly vanished, which of the following would be the most likely and most direct result? O a. There would be no more pathogens on Earth. O b. Human populations would thrive in the absence of disease. O c. Bacteriophage numbers would dramatically increase. Od. The recycling of nutrients would be greatly reduced, at least initially. Next pagearrow_forward
- two ways bacteria are harmful and two ways they are helpful to humans?arrow_forwardThe term "colonization" is best described as: a large group of unicellular organisms presence of bacteria on our body that may not necessarily cause harm a virus that will colonize bacteria and make the disease more virulent all of the abovearrow_forwardWhich of the following does not apply to superbugs? O It is estimated that 70% of antibiotics used in the USA are sold to animal farms. O The CDC reported that 1 million people in the U.S. may contract a superbug every year in the USA. O The CDC predicts that 35,000 people will die yearly from superbugs in the USA. By the year 2050, antibiotic resistant bacteria may kill as many as 10 million people in the world.arrow_forward

The mosquito bites the mammal to transmit this disease. Choose the FALSE statement regarding malaria: O This would be considered parenteral entry. O The mosquito would be considered a reservoir. O This would be considered direct transmission. O The mosquito would be considered a biological vehicle. Question 17 Choose the false statement below. O When bacterial samples taken from the body are grown on nutrient agar medium in the lab, we see many fewer bacterial species turn up on the agar plates than were in the original sample. O Normal flora is found on all surfaces of the body exposed to the external environment including the skin, the covering of the eye, the gastrointestinal tract, the vaginal canal, and the ear canal. O Normal flora is vastly different on different people but surprisingly not so different between parts of the body.arrow_forward
