  1. ABI = Extracted DNA run on an ABI 7700 real time PCR sequence detector.
  2. LC- = Crude C. botulinum culture supernatants run on the Roche Light Cycler. 0-20 cycles = ++++,
  3. 21-30 cycles = +++, 31-40 cycles = ++, > 41 cycles = +
  4. Listed in this table are all strains tested by quantitative PCR for type-specific BoNT. All serotype primer and probe sets were tested against all strains indicated. Standards indicate the plasmid standards used to determine the quantity of BoNT DNA in each sample. Strains tested on the ABI 7700 machine (ABI) included purified DNA from bacterial cultures while samples tested by the Roche Light Cycler (LC) were from crude toxin supernatants.
