| pubmed-article:6761473 | pubmed:abstractText | Conventionally raised suckling mice were given 10(7) spores of a strain of Clostridium botulinum type E. Most but not all infant mice aged 8 through 19 days at the time of administration died after developing symptoms typical of botulism. However, none of the infant mice challenged with the spores at dose levels lower than 10(6) spores/mouse developed illness. | lld:pubmed |
