Webhemolysin BL (HBL), nonhemolytic enterotoxin (NHE) and cytotoxin K. HBL and NHE are three-component proteins, whereas cytotoxin K is a single protein toxin. Symptoms caused by the latter toxin are more severe and may even involve necrosis. In general, the onset of symptoms is within 6 to 24 h after consumption of the incriminated food. WebThe protein was named cytotoxin K (CytK). The amount of protein necessary for 50% inhibition of protein synthesis in Vero cells (≈ 5 × 10 5) was 85 ng (mean value of duplicate measurements). Haemolysis of rabbit red cells was measured after incubation with the toxin for 30 min at 25°C, and 15–20 ng of toxin was required to achieve 50% lysis.
