Describe results for Gram reaction, cell shape and arrangement (look up information) What color changes were observed for each test? Any zones of inhibition (for antibiotics only)?

Antibiotic sensitivity testing: The Kirby-Bauer. 1) What do the following terms mean? a. PPNG b. MRSA 2) How does the MIC test differ from the Kirby-Bauer test? 3) Were all of the conditions of a standardized Kirby-Bauer test met as you performed this assay? If not, which were not? 4) What is the significance of colonies that develop within otherwise clear zones of inhibition? If the laboratory report for one of your patients indicated colonies within the zone, what concerns would you have for your patient?

which of these tests (i.e gram stain, acid fast stain, endospore, oxidation to fermentation, catalase test, oxidase test, PCR test, urea hydrolysis test, aglutination test, northern and southern test.) can be used on the disease causing organism below that can help draw a flow chart or ditochomy key? And will the test results in positive or negative to these these. -Viral gastroenteritis-Plague-Staphylococcal Scalded Skin Syndrome -Cryptosporidiosis -Peptic Ulcer Disease-Campylobacteria Disease-Beef Tapeworm Infestation-C.

A.Why do you plate the cells from the viable count on LB agar without ampicillin? B.If you observe 100 colonies on your 1/100 plate, how many colonies do you expect if everything works perfectly on your 1/1000 plate?

Please answer fast Dilution Problem. A 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.   Growth Problem.A culture with approximately 2x103 cells/mL were incubated. After 3 hours, the number of cells had increased to 3x105. a) How long was the generation time in minutes?b) How many generations have occurred
