Chapter 4, Problem 7CT
Microbiologists have announced the discovery of over 30 new species of bacteria that thrive between the teeth and gums of humans. The bacteria could not be grown in the researchers’ laboratories, nor were any of them ever observed via any kind of microscopy.

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?
You are working for the CDC studying outbreaks of foodborne infectious disease. Your latest case is
an incidence of food poisoning in a fast food restaurant. 5 people have been hospitalized for food
poisoning, so you are working with that hospital to identify the source of the outbreak.
Hospital clinicians have taken samples from each of the 5 patients for culturing. Each bacterial
culture grew one likely microbe, each labelled P1, P2, P3, P4, and P5. All 5 isolates appear to have
the same colony morphology on the plates, and all appear to be Gram-negative rods 1 micron wide
and 3 microns long under the microscope. In addition, all 5 isolates appear to perform the same on
an API 20E test strip that tests bacteria for 20 biochemical abilities. No other testing has been done
yet.
How would you best describe your set of isolates at this moment?
O Each isolate is the same strain, of a different species
O Each isolate is a different strain, of different species

The microbiology department is celebrating the end of the school year in May by holding its traditional picnic on the green. The speeches drag on for a couple of hours, but finally all the faculty and students can dig into the food: chicken salad, tomatoes, onions, salad, and custard pie. By evening, the whole department, except for two vegetarian students who did not eat the chicken salad, is stricken with nausea, vomiting, retching, and abdominal cramping. Several individuals complain of diarrhea. One patient shows signs of shock (low blood pressure). Blood and stool samples are collected from patients, and an analysis of all foods served at the meal is conducted.
Bacteria can cause gastroenteritis (inflammation of the stomach and intestinal tract) either by colonizing and replicating in the host, which is considered an infection, or by secreting toxins, which is considered intoxication. Signs and symptoms of infections are typically delayed, whereas intoxication manifests within…

Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution. Microbial populations grow at different rates based on temperature. One way to measure growth is by turbidity measurements. When bacteria multiply in a broth culture they turn the clear solution cloudy, or turbid. a) in your own words explain the proper steps to Inoculate 5°C sterile broth tube using aseptic techniquearrow_forwardYou have a mixed culture of 2 different bacterial species. One of the species is Gram negative bacilli and the other species is Gram positive cocci. You have noticed that one species is killed by penicillin antibiotics (attacks peptidoglycan) while the other survives. Neither species has antibiotic resistance genes. How can you explain this result? Remember to make direct reference to each bacterial species in your responsearrow_forward

He noticed that a fungus had contaminated one of the agar plates he had streaked with a bacterial species to be studied. The fungus prevented the bacteria from growing in the immediate area surrounding the fungus. Upon further investigation, Fleming found that the fungus produced a substance that was the agent responsible for killing the bacteria. He called this substance penicillin. Given this information, which statement best explains why Fleming's discovery is relevant to the general public today? O Fleming's attention to detail diverted his efforts to investigate bacteria and likely robbed humanity of important discoveries that he would have otherwise made. Fleming's sloppiness in the lab serves as a reminder to all researchers that sterile technique is critical to preventing unwanted fungal growth on bacterial plates. Fleming's discovery enabled the development of chemical substances as antibiotics to…arrow_forwardThe images attached are the photos of bacteria in yoghurt under a misroscope.
