The 16S rRNA-specific primers used for the PCR assay will amplify DNA from closely related species only. Which of the following statements regarding the results seen in lanes 6 & 7 of the gel photograph is MOST ACCURATE?
A. Both represent DNA from oxacillin sensitive isolates of S. aureus
B. Neither lane could possibly represent DNA from oxacillin resistant bacteria
C. It is unlikely that the bacteria represented in these lanes is either S. aureus or S. epidermidis
D. It is likely that the bacteria represented in these lanes are from a family of Gram-negative bacilli
