Abstract

ing carriage of identical epidemic Clostridium difficile isolates in stool samples of a peripartum woman with recurrent C. difficile infection and her asymptomatic baby. The epidemic control strain and the isolates obtained from the mother and the baby had PCR amplification results pos-itive for binary toxin gene cdtB and partial de-letions of the tcdC gene, whereas the nonepi-demic control strain did not. Lanes 1 and 6, 1 kb plus ladder; lane 2, epidemic control strain (restriction enzyme analysis type BI6, courtesy of Dale Gerding); lane 3, nonepidemic control strain (restriction enzyme analysis type J29 or 30); lane 4, isolate from the mother; lane 5, isolate from the baby. documents.
