| The toxins are pro-inflammatory enterotoxins, but toxin B is a more potent cytotoxin. |
| The biological, particulate, endotoxin, cytotoxin and chemical residue loads are regularly verified by independent certified labs. |
| Previous studies have indicated that there is considerable variation in the quantity or activity of vacuolating cytotoxin produced or secreted by H. pylori isolates. |
| Toxin detection by a tissue culture cytotoxin assay followed by neutralisation with specific antiserum is often considered the standard. |
| Comparative studies of EIA kits reported that the sensitivity and specificity are slightly lower than cytotoxin assays. |
| The possibility that a cytotoxin may play a role in the pathogenesis of EPEC infection had been suggested. |
