What is the importance of knowing the genetic information about anthrax?
Genetic information about B. anthracis, particularly to determine genetic similarity among strains, is an important part of a disease investigation, but it is not immediately required for taking action to prevent or treat anthrax in those who may have been exposed to or infected by B. anthracis. Genetic information is often used to determine the similarity of strains if a common source is suspected. Does the similarity in strains from Florida, New York, and Washington, D.C. mean that they came from the same source or are these just the most common strains? The strains of anthrax identified in Florida, New York, and Washington, D.C., are similar and consistent with a naturally occurring strain that shows no evidence of genetic alteration or bioengineering. All are sensitive and susceptible to the antibiotics recommended by CDC for those who have been exposed to or infected with B. anthracis.
