Blood Agar (Aerobic) MacConkey EMB PEA Mannitol Salt Agar Chocolate Agar Nutrient Agarwhy is it important that a small amount of inoculum be used in preparation of an agar slant?You are transferring a bacterial culture from a tube of broth to a Petri dish containing trypticase soy agar. Please list the steps that are necessary to make the transfer successfully and with minimal risk. of contamination.
- In a bacterial culture on an agar plate, what is a zone of inhibition? An area where the growth of bacteria is increased compared to the rest of the agar plate An area where the growth of bacteria is prevented or reduced compared to the rest of the agar plate An area where the growth of bacteria is not affected compared to the rest of the agar plate An area where the the agar becomes contaminated with moldMacConkey agar inhibits the growth of Gram-positive bacteria while encouraging the growth of Gram-negative bacteria. It also can determine if some bacteria use lactose. Define what type(s) of media MacConkey agar is, using as many terms in the answer list as are applicable.Describe the appearance of an S. agalactiae colony grown on blood agar.

Please help explain based on what kind of microorganisms it allows to grow.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 and the second will be Gram negative. 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. Can you please help me find the dichotomous key . Thank you !MALDI-TOF, is a method for identifying bacteria quickly. Look at this graphic then put the steps in order. Please follow a pathway of steps involving the Bacterial Culture: Get a readout of species identification and (sometimes) whether it is resistant or susceptible to antibiotics. Use colony from a nutrient agar plate. Prepare the sample, run it through MALDI-TOF machine. Grow a clinical sample on nutrient agar.
