A patient is experiencing high fever and body aches from an infected skin wound. You suspect a bacterial infection and perform a
Step by step
Solved in 3 steps
- You are a doctor at a field hospital deep in the Amazon jungle. A local villager comes to you sick with nausea, diarrhea and vomiting and you suspect they may have food poisoning. Several different types of bacteria can cause food poisoning including Campylobacter jejuni, Staphylococcus aureus, and Salmonella tyhphirium. How will using a microscope help you to identify which of the three bacteria are responsible for making your patient sick so that you can administer the correct antibiotic?Metachromatic granules are concentrated ____________found in _______ .a. fat, Mycobacterium c. sulfur, Thiobacillusb. dipicolinic acid, Bacillus d. PO4, CorynebacteriumBelow is an image of a stained microorganism. Choose the BEST answer for the following questions pertaining to the image shown.
- A student inoculates Escherichia coli into two test tubes containing the same sterile liquid medium, except the first tube also contains a drop of a chemical disinfectant with an antimicrobial effect. After 24 hours of incubation, the first tube remains clear while the second tube becomes cloudy with bacteria. How would you go about determining if the chemical is bacteriostatic or bactericidal?Infections among hospitalized patients are often related to the presence of a medical device in the patient. Which conditions favor the formation of biofilms on in-dwelling catheters?Which of these structures is most resistant to chemical disinfection? (Which is hardest to kill?) fungal spores chlamydia bacteria protozoa cells bacterial spores
- A patient was admitted to the ER with severe virulent E. coli bacteremia and was given a high dose of intravenous ciprofloxacin antibiotic, to which the patient was not allergic. The patient develops fever and chills shortly afterward the administration of the antibiotic. Which of the following best describes the probable cause? Group of answer choices A. The Gram-negative E. coli released the endotoxin in the form of lipid A from the disintegrated lipopolysaccharides (LPS) upon death by the antibiotic leading to chills and fever. B. The Gram-negative E. coli released the endotoxin in the form of Protein A from the disintegrated lipopolysaccharides (LPS) upon death by the antibiotic leading to chills and fever. C. The Gram-positive E. coli released the endotoxin in the form of Protein A from the disintegrated lipopolysaccharides (LPS) upon death by the antibiotic leading to chills and fever. D. The Gram-positive E. coli released the endotoxin in the form of lipid A from the…Use the following diagram to explain how Pasteur’s swan-necked flasks prevent contamination of sterile broth the flasks.Describe what happens to the sterile broth (a) after it has beenallowed to cool as in (b). What happens to the broth after theflask has been tipped enough to let the broth come in contactwith the dust and microorganisms and is tipped back as in (c)?A bacterium has the following characteristics:∙ It adheres to the human intestinal lining using a feature that protects it from phagocytes, bacteriophages, and dehydration∙ It can survive being boiled∙ It contains no plasmids and relatively little peptidoglycanWhich of the following characteristics allows this bacterium to adhere to the intestinal lining? Group of answer choices A. fimbriae B. pili C. an endospore D. a flagellum
- Many people use antimicrobial soap to kill bacteria on their hands. However, overuse may increase the risk of infection. How could this occur?Once these pathogens enter the host the difference in environmental conditions signals for them to germinate and turn into growing cells. Compare Inhalation anthrax (Bacillus anthracis) to Tetanus (Clostridium tetani). Besides endospores used in transmission, what is a simple explanation to help explain how each microbe survives and grows in each location?During the fall 2001 bioterrorist attack in which anthrax endospores were sent through the mail, one news commentator suggested that people should iron all their incoming mail with a regular household iron as a means of destroying endospores. Would you agree that this is a good way to disinfect mail? Explain your answer. Which disinfectant methods would be both more effective and more practical?
