- What is the premise of the test? What would the results look
like for each of these two bacteria? using the NB-disc sensitivity
for
Staphylcocccus epidermidis
Staphylococcus saprophyticus
Homework Answers
NB disc sensitivity test is performed inorder to identify Staphylococcus saprophyticus infection which is coogulase negative.
one of the main pathogen that causes UTI is S saprophyticus. Performing coogulase test can help us identify if the pathogen is coogulase positive Staphylococcus aureus or negative species. Among coogulase negative- the suspected bacteria can be either S saprophyticus or S epidermidis which is normal flora. so to differentiate them Novobiocin disc sensitivity test is performed. This disc is placed on blood agar which has inoculated pathogen. It is to check if the bacteria is sensitive or resistant to it. S saprophyticus is sensitive whereas others are resistant.
S epidermidis- resistant to NV and so shows no zone
S saprophyticus is sensitive and therefore shows zone around the disc.

What would the results of a Sanger sequencing read look like if you accidentally omitted the deoxyCTP (dCTP) from the reaction? Multiple Choice No Cs could be incorporated into synthesis products, and so only peaks corresponding to the smallest synthesis products - none of which include a C - will appear. The results would be normal; dCTP is not required for Sanger sequencing - the only kind of C needed is ddCTP. All of the synthesis products would end with...
