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.
- I'm having trouble identifying the type of bacteria I have cultured. I know that it is gram-negative and cocci in shape, it grows wonderfully on the MSA plate but did not grow so well on the EMB plate, and it is non-motile. It has a yellow color but I'm just not sure what it is. It was obtained from a public area. Any ideas?I completed the chart, and I'm supposed to figure out the unknown bacteria, there are 12 unknown culture, out of which of them resemble my chart the most? (My chart is the one in pink with the information filled out)Purpose Solve the identity of an unknown bacterial specimen by creating a dichotomous key and using the staining, culturing and biochemical identification procedures you have learned about during the semester. 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 You must write up your OWN dichotomous key for all the possible unknown organisms listed on above. Writing this key requires you use the same type of reasoning used in the Dichotomous key lab. The first step of the key will be the Gram Stain. Subsequent steps will include biochemical tests only. Please help me with this question. Thank you so much !
