How is it possible for strict anaerobic bacteria to
cause a disease in humans?
Strict anaerobe pathogens produce toxins that
damage the host cells.
There are parts of the human body where oxygen is
absent.
Strict anaerobes can hide from the immune system
rather well.
Strict anaerobes can break down the oxygen
creating an anaerobic environment in the body.
Stomach acid has a pH of approximately 1 which is very strong. This kills most microbes that reach the stomach. This is the ___ line of defense.
chemical
physical
mechanical
cell mediated

- When food leftovers are stored in a refrigerator, how does this help prevent food borne illnesses? Group of answer choices Low temperatures deactivate any toxins that might be produced by microbes. Low temperatures inhibit the metabolism and growth of microbes. Low temperatures disrupt microbe membranes and kill any microbes that are present. Low temperatures prevent microbes from forming biofilms.arrow_forwardGram-negative bacteria are not killed by penicillin because they: do not have ribosomes. have an outer membrane layer covering their peptidoglycan cell wall. have two layers of peptidoglycan. do not have peptidoglycan. their ribosomes are protected with their own outer membrane layer.arrow_forwardThe 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.arrow_forward
- Which of the following statements about E. coli is true? Some infections can be fatal to humans. It occurs naturally in food crops. Most people can ingest it without harm. O It dies quickly outside of its host.arrow_forwardIn term of the microbes in human body, Are the areas the same or are they different per individuals? Why?arrow_forwardWhich microbes predictably cause NO negative effects when they are inside you? Microbes that are only transmitted vertically. All horizontally transmitted microbes. Microbes that are transmitted horizontally with the involvement of a vector. Microbes that are transmitted horizontally without the involvement of a vector.arrow_forward
- What happens when mice that have no microbes are inoculated with healthy fecal material from normal microbe-rich mice? They lose weight because of horizontal gene transfer They gain weight because the new microbes help break down food The mouse genome acquires new genes from the microbes Their immune systems are overwhelmed and they diearrow_forwardIf someone is contaminated with a bacterium from the environment, are they guaranteed to develop a disease? O Yes, contamination precedes disease and only one microbe is needed for disease development. Yes, a contamination implies that the patient will develop an illness. O No, contamination is just the mere presence of microbes in or on the body. O No, only non-living surfaces may be contaminated.arrow_forwardDo you think that it is correct that the blood has no microbiota? YOU CAN MAKE A CASE EITHER WAY. This is a question where I just want you to think and make an argument for or against the statement in the book that the blood has no microbes.arrow_forward
- Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario. Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote? You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab. What is one experiment you could do, involving culturing the organism?arrow_forwardMatch the cells structure or chemicals with their role in the infection processarrow_forwardWhich of the following is not an example of the physical, mechanical, and chemical barriers at body surfaces that prevent most microbes from entering the internal environment?
