The levels of organisms and toxin in the feces were measured throughout the 81-day period in hospital. The maximum levels detected were 2.46 x 10(8) C. botulinum type A colony-forming units and 64,000 mouse 100% lethal doses of type A toxin per g (wet weight) of feces. C. botulinum toxin was also detected in two samples of the patient's serum, collected 3 and 10 days after admission. Improvement in the patient's clinical condition occurred before the levels of organisms and toxin in the feces reached their maxima. A slight improvement may also have occurred while toxin was still present in the serum.en© 1983, American Society for MicrobiologyFecesHumansClostridium botulinumBotulismBotulinum ToxinsInfantMaleJournal article003000895910.1128/jcm.17.1.13-15.1983A1983PV343000032-s2.0-0020676554107613Paton, J.
