Infant Botulism. The First Culture-Confirmed Danish Case

Abstract

Infant botulism is caused by intestinal colonization by Clostridium botulinum, C. barati or C. butyricum. Infant botulism has only rarely been reported outside the USA. A 3-month-old boy developed constipation, lethargy, feeding difficulties and descending, severe, symmetric weakness. He was breastfed but had also been fed honey. Supportive care led to complete recovery. The serum was positive for C. botulinum toxin type A-F (mouse toxin neutralization assay). A strain of C. botulinum producing toxin type A and E was identified in the stool. C. botulinum was identified in a jar of honey of the same brand as the honey fed to the patient.
