Abstract

SUMMARY: Vero cytotoxin (VT) production has been studied in 34 strains isolated from animals with enteric diseases. The strains were tested by DNA hybridization with probes for VT1 and VT2 sequences and also in toxin neutralization experiments with specific antisera. Twenty bovine strains, belonging to nine different O serogroups, produced VT1 or VT2 but not both toxins. In contrast, all 14 porcine strains of four different O serogroups produced VT2 only. Six of these porcine strains, belonging to serogroups 0138, 0139 and 0141, were isolated from cases of oedema disease. In general, the porcine isolates produced toxin at a lower level than the bovine strains.
