First Case of Infant Botulism Caused by Clostridium baratiiType F in California

ABSTRACTIn late 2003 a severely hypotonic neonate, just 38 h old at onset of illness, was found to have infant botulism caused by neurotoxigenic Clostridium baratiitype F. Environmental investigations failed to identify a source of this strain. This is the youngest patient reported to have infant botulism and the fifth instance of infant botulism caused by C. baratiitype F.
