- Describe characteristics of Streptococcus Agalactiae in the Agar: (How does colonies look like (color) and explain does it grow on that agar. (Don't have to write the incubation period) ~ Only describe how would it look like on the Agar: Blood Agar (Aerobic) MacConkey EMB PEA Mannitol Salt Agar Chocolate Agar Nutrient AgarA student needed to transfer bacteria from a broth culture to an agar plate. Below is the step-by-step what was done to accomplish this. The transfer of bacteria was not successful because of which step? 1. Cap of the broth culture is removed 2. The mouth of the bottle is flamed 3. The loop was flamed 4. The loop was inserted into the culture to pick up the bacteria 5. The loop was flamed 6. The loop containing the bacteria was used to introduced to spread the agar plate 7. The plate was placed in an incubator at 30 CelciusYou 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 flask
- Ten grams of hamburger were added to 90 mL of sterile buffer. This was mixed well in a blender. One-tenth of amL of this slurry was added to 9.9 mL of sterile buffer. After thorough mixing, this suspension was further dilutedby successive 1/100 and 1/10 dilutions. One-tenth of a mL of this final solution was plated onto Plate Count agar.After incubation 145 colonies were present. How many colony-forming units were present in the total 10 gramsample of hamburger?The figure attached shows the colonies on Eosin Methylene Blue Agar (EMBA) plate. Make a description on the picture.You 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:
- 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…Put the following Steps of gram smear in order Create a bacteria Add crystal violet to the bacterial smear. Rinse with water after 60 seconds. Allow the smear to air dry and then heat fix it. Add gram iodine to the smear, let it sit for 60 seconds and rinse water decolorize with 95% ethanolfoe 5-10 seconds and then rise with water Blot dry with bibulous paper Add safranin to the smear and let sit for 60 seconds, then rinse with water Observe using oil immersionWhy is washing with Hank’s balanced salt solution with 0.5% antibiotic-antimycotic done for Splenocyte Preparation?

Which of the following could be the reason for the absence of colonies? A) You centrifuged your electroporated cells for 30 sec at 16,000 rpm instead of 4,000 rpm before plating them B) You added sorbitol+YPD to your cells thirty minutes after pulsing your cells C) The Zeocin had not been added to the plates when they were made. D) All of the above E) Both a and b onlyA culture of Staphylococcus is diluted as follows:(1) 20mL are added to 80mL of water.(2) 10uL from (1) are then added to 9.99mL of water.(3) A 10-2 dilution is made from tube # (2).(4) 100uL from (3) are plated for a pour plate and incubated.
