Anthrax strains
As I understand it, anthrax is anthrax. There are different strains, cetainly, but the cutaneous, inhaled, and ingested forms of the disease are simply a matter of how the spores enter the body... the same spores can cause each of the three forms.
The (presumably) low grade used in Florida (and all the cases so far?) indicates to me that it is a less than professional operation.
