RESUMO

A 4-month-old boy presented with symptoms and signs characteristic of infant botulism. Examination of feces revealed Clostridium botulinum type B and type B toxin. The numbers of C. botulinum and the amount of toxin in feces were measured throughout the 4-week period in hospital. The maximum numbers and amounts were detected in a fecal specimen collected 16 days after admission: this contained 8.4 X 10(6) C. botulinum type B colony-forming units and 61,440 mouse 100% lethal doses of type B toxin per g (wet weight) of feces. This latter figure is the highest fecal toxin titer reported yet for a case of infant botulism. By day 16, however, substantial improvement in the patient's clinical condition had occurred. This suggests that initiation of recovery from infant botulism is not necessarily preceded by a reduction in the numbers of C. botulinum organisms and the quantity of toxin in the gut.
