There was an article about this posted just a week or so ago which claims otherwise and specifies the range within which these spores must be in order to be effective when inhaled. And it claims these were within that range.
You are misunderstanding. Yes, particles do have to be within a certain range (1 to 5 microns) to be deadly when inhaled. But ALL ANTHRAX SPORES ARE IN THAT RANGE. It's when lots of spores are CLUMPED together into BIG CLUMPS that are larger than 5 microns that they are caught by hairs in the nose and do not get inhaled, or they are coughed out.
You should not mistake what is said about "particles" or "clumps" as pertaining to spores. INDIVIDUAL spores come in only one size. This is a BASIC SCIENTIFIC FACT, and no report regardless of where you read it will change that.
