title: Survey of neuraminidase production by Clostridium butyricum, Clostridium beijerinckii, and Clostridium difficile strains from clinical and nonclinical sources.
abstract: Neuraminidase production was investigated in 57 Clostridium butyricum strains, 16 Clostridium beijerinckii strains, and 25 Clostridium difficile strains. Neuraminidase activity was found only in C. butyricum strains originating from one human newborn with neonatal necrotizing enterocolitis, two newborns with hemorrhagic colitis, one infected placenta, and one adult with peritonitis, It was concluded that neuraminidase was not a major virulence factor in C. butyricum strains.
