title: Neonatal infections in puppies caused by Escherichia coli serogroups 04 and 025.
abstract: Three cases of neonatal E. coli infection in Newfoundland dogs are described. The serological examination showed that the implicated E. coli belonged to sero-group 04 in two outbreaks while sero-group 025 was responsible for one outbreak. In one of the kennels with implication of 04, this 0-group was also isolated from adult dogs with diarrheal conditions.
