  1. a +/- indicates presence/absence of 101 bp band on agarose gel. Samples are purified DNA from bacterial cultures as described in the Methods section.
  2. b Samples originate from filtered culture supernatants containing crude toxin. +/- indicates presence/absence of 101 bp band on agarose gel. nd = not detected, nt = not tested.
  3. c BoNT E-producing strain of C. butyricum isolated from an infant case in Italy.
  4. d BoNT F-producing strain of C. baratii.
  5. eNon-toxin producing strain of C, baratii.
  6. Results from conventional PCR detection of NTNH. A (+/-) indicates presence/absence of 101 bp band by agarose gel, respectively. DNA results indicate PCR detection of NTNH in purified DNA from both C botulinum and other Clostridial strains. Culture supernatant results indicate amplification of DNA within crude culture supernatants. NT indicates samples that were not tested.
