The images attached are the photos of bacteria in yoghurt under a misroscope. According to these images and your own knowledge, can you make a biological drawing of bacteria in yoghurt ( in a circle) and identify the types of bacteria accurately?
Your biology lab instructor gives you a petri dish of agar covered with visible colonies. Your lab partner says the colonies are viruses, but you disagree. How do you know the colonies are bacteria?
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?

- There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiple the series of dilutions together to find the final dilution value. If 3 serial dilutions are performed, each with a value of 0.01, what is the cumulative dilution? Express your answer as an exponent, e.g. 0.1 would be 1e-1 and 0.01 would be 1e-2arrow_forwardThe question is: A patient has arrived at the doctor complaining of acute respiratory symptoms (cough, runny nose, fever). The patient explains to the doctor that he was at a concert the night before and shared a water bottle with a friend who had similar symptoms. The doctor tells the patient that he has a virus. a.) What form of replication do you think this virus does use? How do you know? b.) Can the doctor prescribe an antibiotic for this patient?

- How do I go about drawing a biological drawing of Sarcina lutea? Apparently it has been reclassified as Micrococcus luteus, and I have found an image for me to base my drawing on (image attached), but I don't exactly know which parts to label. Hope I can get some help on this.arrow_forwardThe 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…arrow_forwardList all the antibiotics in the above table that work through destroying the bacterial cell wall.

- Why can't you see the bacteria when you first swab a plate?arrow_forwardImagine that you are a student in Alfred Hershey and Martha Chase’s lab in the late 1940s. You are given five test tubes containing E. coli bacteria infected with T2 bacteriophages that have been labeled with either 32P or 35S. Unfortunately, you forget to mark the tubes and are now uncertain about which were labeled with 32P and which with 35S. You place the contents of each tube in a blender and turn it on for a few seconds to shear off the phage protein coats. You then centrifuge the contents to separate the protein coats and the cells. You check for the presence of radioactivity and obtain the following results. Which tubes contained E. coli infected with 32P-labeled phage? Explain your answer.
