Clostridium difficile isolation in neonates in a special care unit. Lack of correlation with necrotizing enterocolitis.
The stools of 78% of 45 infants in a Special Care Baby Unit yielded Clostridium difficile on culture, and in 67% of these it was possible to detect C. difficile toxin by means of a tissue culture technique. The stools of six of the seven infants with necrotizing enterocolitis were positive for C. difficile, but neither of the two most severely affected contained C. difficile toxin. The incidence of C. difficile isolation was similar in infants treated by exchange transfusion, those treated with antibiotics, those of low birth weight, and those with respiratory distress. The serum of only 2 of 28 infants and 1 of 20 mothers contained a neutralizing factor to C. difficile toxin. The present study does not support a role for C. difficile in neonatal disorders and in particular necrotizing enterocolitis. The reason for the apparent tolerance of the neonatal bowel to C. difficile toxin remains to be explained.
