What is the reagent used to test Dnase test?
There are no reagents added when a Dnase test is performed. The test is done in a methyl green medium with a pure inoculum culture. If halos form around the culture than Dnase is present.
Is the media for oxidase test selective or differential?
media used for oxidase test is non selective media
Why 1M of HCL is used in Dnase test?
what is the role of HCL in the DNase experiment
Why is the DNase test only incubated for 24 hrs?
For the DNase test, 24 hours is sufficient to be able to examine the culture. The test result should be recorded after this amount of time has passed, and then it must be discarded.
What is the purpose of the anti-DNase-B test?
The anti-DNase-B (ADB) test is performed to determine a previous infection of a specific type of Streptococcus, group A beta-hemolytic Streptococcus.
Does m luteus produce a positive or negative dnase test?
yes
What is selective test?
selective type test is not a hard test if youstudy hard
Would omitting NaCl alter the medium's specificity or sensitivity?
The answer is Yes, only if this is in reference to a selective and/or differential medium. Specificity is the ability of the test to identify negative results while sensitivity is the ability of a test to detect positive results. So, if taking out the NaCl effects your ability to interpret your data results then it in someway has effected your sensitivity and specificity.
Describe a positive DNase test?
It means that the presence of certain bacteria are there. You will need to go through the whole test to find out if this is true.
What is selective type test?
Selective test is a very very hard test. Its only for 0.01% of Australian children can pass this test.
