Hi Guys, Please let me know the answer for this Q. I am confused
A fatal case of necrotizing fasciitis (NF) caused by a community-acquired invasive group A streptococcus (GAS) infection occurred in the Spokane, Washington area. Four other cases of invasive GAS infection that were clustered in time and in the geographic area were identified. All five of the GAS isolates were studied for their epidemiologic relationship. What type of testing of the isolates would best provide evidence that these five cases represented a common-source outbreak?
A)antibiotic susceptibility B)bacteriophage typing C)capsular serotyping D)protein A serotyping E)pulsed field gel electrophoresis (PFGE) of chromosomal DNA

I guess the explaination is that finding the same DNA in all the five isolates will confirm a common source . ___________________ I can't change the direction of the wind, but I can adjust my sails to always reach my destination.

PFGE separates strands of DNA to tell the differences of the samples.
