C. perfringens toxin genes found in infants that developed NEC compared to control infants. Percentages were calculated out of the total number of control infants (n = 91) and infants that developed NEC Bell stage 2 (confirmed) or 3 (severe) (n = 5). Two infants who developed NEC Bell stage 1 (suspected) could not be categorised as cases or controls so were not included. A toxin gene was scored as present if it was found in any C. perfringens isolate found in an infant’s faecal samples during the course of either their whole time on the neonatal unit or up to the last sample prior to NEC development. The table shows the counts within the two groups and the relative percentages for toxin occurrence
