Which of the Following is a Fairly Reliable Method of Characterizing

Question

Which of the following is a fairly reliable method of characterizing strains of S. aureus?
A)complement fixation
B)protein fingerprint
C)genome typing
D)LPS pattern

Accepted Answer

Genome typing, such as pulsed-field gel electrophoresis (PFGE) or multilocus sequence typing (MLST), is a reliable method for characterizing different strains of S. aureus. This method looks at the DNA sequence of the bacteria to identify genetic variations between strains. Complement fixation, protein fingerprinting, and LPS pattern analysis are not as specific or reliable as genome typing.
