With your tests you now figured out that your patient has a Staphylococcus infection, and you would like to
know if the infection is caused by Staphylococcus aureus or by Staphylococcus epidermis. What test can you do
next to see if your patient indeed has a Staphylococcus aureus infection?
O You can isolate the pathogen from the patient and grow it on a mannitol salt agar. Staphylococcus aureus can ferment
mannitol turning the agar plate yellow. Staphylococcus erpidermis cannot ferment mannitol and the agar plate stays red.
O You can isolate the pathogen from the patient and grow it on a mannitol salt agar. Staphylococcus epidermis can
ferment mannitol turning the agar plate yellow. Staphylococcus aureus cannot ferment mannitol and the agar plate stays
red.
O There is no way you can distinguish between Staphylococcus aureus and Staphylococcus erpidermis
O you do a Gram stain. Staphylococcus aureus will stay purple as it is Gram positive and Staphylococcus erpidermis will
show up as…
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 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_forwardAbigail did not dry the top of her agar plate and stored it top up. Now she wants to count colonies but there is a smear over the entire plate. She was working with E. coli. Why does she have a smear?arrow_forwardYou were tasked to prepare four petri plates. Three of the petri dishes were inoculated using different samples. The plates were prepared from the following: Plate A: oral swab after brushing Plate B: cat’s paw Plate C: exposed in air for one hour Plate D: uninoculated The plates were incubated at 37˚C for 24 hours. The following results were obtained: 1. Compare the growth of the cultures found in Plates A, B, C and D. Which among the four plates has shown the most growth? Why do you think so? 2. Describe the appearance and abundance of the colonies found in your four plates. What possible type of microorganisms are found in your plates? 3. Although sparse, there is still visible growth of microorganisms in Plate D (uninoculated plate). Where do you think the microorganism came from? REFERENCES:arrow_forward
- Two patients, with identical medical histories are in adjacent hospital beds. Each is infected with Streptococcus pneumoniae. Patient A's infection progresses to pneumonia while Patient B's infection resolves quickly. The microbial stain of the lung fluid from Patient A indicated the bacterial cells had a capsule, while Patient B's lung fluid stain did not. Why did the capsule affect the course of the infection in Patient A?arrow_forward45-year-old male had been working in his garden when he scratched the knuckle of his right arm during digging in ground with a spade, he immediately washed the area but noticed later that night that the knuckle became red, warm to the touch and swollen. He went to the hospital, the doctor ordered a Gram stain and culture on the pus extracted from the wound. The culture grew the following organism and the Gram stain from the wound showed the following results:Based on the previous results, answer the following questions:1. As a microbiologist, describe what you see on the Gram stain taken from the wound site. And give a preliminary report on what you see on the culture plates. What is the probable Genus and species?2. Name 2 tests that can be done to positively identify this organism.3. What are the media used to culture the sample, and what is the type ofhemolysis seen?arrow_forwardA hospital lab technician working with a particular strain of streptococci culture on blood agar plates suddenly came down with a case of sore throat. Using Koch's Postulates as a guide, develop a step by step experimental protocol to determine if the organism growing on the plates was in fact the cause of the technician's sore throat.arrow_forward

Make a description on the picture.arrow_forwardA farmer working on a piece of machinery gets his shirtsleeve caught in a moving piece of the equipment. His shirt is sliced, and a sharp blade covered in mud slices through his upper arm. He attempts to control the bleeding and immediately seeks medical attention. After 3 days, he develops a fever and his arm becomes extremely swollen and painful. Pulling back the bandages, he finds that the wound has become blackened and is leaking bloody fluid. Microscopic analysis of the fluid reveals the presence of gram-positive bacilli. a. Discuss what condition the patient is suffering from and the likely causative agent of this infection. b. Explain how the patient contracted this pathogenic microbe and what virulence factors contributed to the pathogenesis seen at the wound site. c. In addition to antibiotics, the physician prescribes hyperbaric therapy. Describe what this treatment involves and how it could be therapeutic to this patient.arrow_forwardYou mixed up the numbers on the tubes when you inoculated the mannitol salt agar (MSA) plate. You do not know if you grew staph epidermis or E. coli. You found that the organism growing on the mannitol salt agar remained red after incubation. It is most likely that the organism is E.coli. a) True b) Falsearrow_forward
- You are working in a lab studying Streptococcus pyogenes as a cause of necrotizing fasciitiis. You have an overnight culture that you want to know the starting concentration of, so do a set of six 1:10 serial dilutions (putting 1 mL from the stock into a 9 mL blank), with tube #1 being 1:10, #2 is 1:100, etc. You plate 0.1 mL from tube 5 onto a blood agar plate and the next morning count 134 colonies. How many bacteria (measured in CFU/mL) were in the overnight culture flask? A. 1.34 x 10^4 CFU/mL B. 1.34 x 10^5 CFU/mL C. 1.34 x 10^6 CFU/mL D. 1.34 x 10^7 CFU/mL E. 1.34 x 10^8 CFU/mL F. cannot tell based on the data given - you'd need to know the volume of the original culture flaskarrow_forwardIn order to view Treponema pallidum, the causative agent of syphilis, under the microscope, you can tag the specimen with an antibody-flourescein dye complex and look under a microscope that projects UV light onto the specimen. What test are you using?arrow_forwardA patient comes to the hospital complaining of pain after going to the bathroom. This has been on going for the past couple of days and the pain is steadily increasing. A urine and blood sample are taken and determine there is a bacterial infection.
