Refraction

Which staining technique is best used to view the cell wall of most bacteria

The Gram Stain

Wendel arrives at the doctor's office. He reported that he had been suffering from a persistent cough for several weeks, and recently the exudate (phlegm) had traces of blood in it. A PPD (dermal skin test for Tb was positive: however, Wendel was born in Kenya and has received the BCG vaccine, so the results were not considered confirmatory. In an attempt to verify his diagnosis a chest x-ray was ordered, the image showed a nodule characteristic of either Tuberculosis or a tumor.
Which staining technique would have to be run to fully confirm a tuberculosis infection in Wendel?

An acid-fast stain

During a Gram Stain, a bacterium with a thick cell wall will retain which of the below dyes?

Crystal Violet

Which of the below techniques is the only one to use acidic dye?

The Negative stain

Microbiology uses immersion oil to compensate for changes in which fundamental aspect of visible light?

Velocity

Which staining technique would be performed first during the phenotypic ID of a bacterium?

Gram Stain

Which form of microbial identification will yield the fastest results?

Serotyping

Which form of microbial identification is the most accurate?

Genotyping

Which form of microbial identification is only useful as a confirmation of a suspected pathogen rather than identification of an unknown pathogen?

Serotyping

Which of the below is not a form of phenotyping
