The number of bacterial cells in a culture broth is to be determined by a culture technique. Serial dilutions were performed and a 1 mL aliquot from each dilution was mixed with warm molten agar and poured into a Petri dish. The numbers of bacterial colony forming units (CFU) after overnight incubation are shown in the table below. What is the number of colony forming units per mL of the culture broth? Choose only the most appropriate plate for your calculation. Give your answer as the number only (do not add text for the units). You may use scientific notation with the format 1.12e+6 (that is, 1.12 x 106 cfu/mL). (Note: Canvas will then display your answer a whole number.)

The number of bacterial cells in a culture broth is to be determined by a culture technique. Serial dilutions were performed and a 0.1 mL aliquot from each dilution was spread onto Plate Count Agar (PCA).

Examine the image below. The bacteria in this image have been treated with gram straining procedure. Indicate the following information: A. Shape....... gram stain( +) , Gram (-) or both B. Stained color under microscope C. PG Wall thick, thin or both
A lab technologist calibrates her microscope and finds that 7 stage divisions are equal to 38 ocular divisions. The entire scale on the stage micrometer is 1 mm long and has 100 equal divisions. The technologist measures a coccus-shaped cell and determines that the cell is 4 ocular divisions in length. What is the length of this cell in µm? Show all calculations.
I posted this question same person answered twice and I don’t understand the handwriting so plz if same person gonna answers then plz type don’t post same answer over again
start with the results of your Gram Stain. In the spaces labeled appearance& observations, indicate what you see. For instance, "red, long, rod-shaped cells." Under Results indicate the correct term that goes along your observation. For the gram stain, it is sufficient to write the word "positive" or negative in this space.
A patient comes into a hospital and has what appears to be an infection. Your microscope is broken so staining is not an option. Design an experiment to determine if the infection is caused by gram positive or gram negative bacteria.

You must write up your OWN dichotomous key for all the possible unknown organisms listed below . The first step of the key will be the Gram Stain. Subsequent steps will include biochemical tests only. Solve the identity of an unknown bacterial specimen by creating a dichotomous key and using the staining, culturing and biochemical identification procedures . Possible Organisms Alcaligenes faecalis Enterobacter aerogenes Enterococcus faecalis Escherichia coli Proteus vulgaris Pseudomonas aeruginosa Salmonella arizoniae Staphylococcus aureus Staphylococcus epidermidis Staphylococcus saprophyticus Streptococcusbovis Streptococcus pyogenes Imp Note - the test should be performed using any of the following tests stated below. Bile Escalin test, Oxidaze test, Blood Agar , Catalese Test, Mannitol salt agar . Thank you !
Create a dichotomous key Use the following bacteria and place them at the top of your key: Escherichia coli Klebsiella pneumoniae Staphylococcus epidermidis Bacillus subtilis Use the following five criteria to create the couplets: Morphology Gram reaction Acid Fast Reaction Endospore Positive/Negative Capsule Positive/Negative
