Question 6 1.5 points Save Answer Bacterial ID Flow Chart.docx A student in a microbiology lab was assigned the task of determining the identity of a bacterial species. First she performed a quadrant streak on a TSA plate. After 24 hrs. incubation, she aseptically picked up a portion of a single isolated colony for a gram stain. Her results indicated purple spherical-shaped bacteria that grew in grapelike clusters with no apparent endospores. She then performed a series of biochemical tests with her results listed below. Use the attached Bacterial ID Flow Chart to obtain the genus and species of her organism. Catalase test: bubbles observed Chrom Starch hydrolysis test for amylase: negative MSA plate: pink growth observed Gamma hemolytic on blood agar, facultative anaerobe What is the name of her organism? O Staphylococcus aureus Neisseria species Bacillus subtilis Staphylococcus epidermidis Moving to another question will save this response. Question 6 of 65 > >> SA ca 31

Answer 1

It is staphylococcus epidermidis.

It is a gram positive bacteria, which produce grape like colonies.

Both staphylococcus aureus and staphylococcus epidermidis have same features except on MSA plate, staphylococcus aureus form yellow-golden colony and staphylococcus epidermidis form pink colony.

So Corrrect answer is option 4.

Hope it helps you.
