Concept #1: Bacterial Pathogens

Concept #2: Viral Pathogens

Concept #3: Parasitic Pathogens

Practice: Escherichia coli is a pathogen that causes urinary tract infections (among other types of infections). It is a prokaryote with a cell membrane and a cell wall. Which of the following correctly describes E. coli?

Practice: Ascaris lumbricoides is a species of helminths (worms). They infect the gut, usually in patients who have spent time in developing countries. Which of the following correctly describes Ascaris?

Practice: A certain pathogen (whose name gives away the answer) has a protein coat around an RNA genome. It infects cells in the GI tract of its host and causes nausea/vomiting. Which of the following correctly describes this pathogen?

Additional Problems
Which answer choice does NOT contain at least one cellular process inhibited by antibiotics? A. prokaryotic protein synthesis and prokaryotic cell wall synthesis B. eukaryotic protein synthesis and prokaryotic cell wall synthesis C. eukaryotic protein synthesis and eukaryotic cell wall synthesis D. prokaryotic protein synthesis and eukaryotic cell wall synthesis
Why must most antibiotics be given some time to take effect on a disease-causing population of bacteria? A. Quick regeneration time of disease-causing bacteria cells allows antibiotic resistance to be transferred during the beginning of treatment. B. All three answer choices are correct. C. Most antibiotics are large molecules and, therefore, take a considerable amount of time to reach the location of the disease-causing population in the body. D. Most antibiotics do not work on existing bacteria, so one must wait until the original disease-causing cells die off. Prokaryotes can live for several days.
