摘要：

Ectoine (ECT) is a bacterial compatible solute with documented protective action however no data are available on its effects on various cells against bacterial toxins. Therefore, we determined the in vitro influence of ECT on bovine erythrocytes subjected to staphylococcal alpha-haemolysin (HlyA). The cells exposed to HlyA alone showed a distinct haemolysis and reduced glutathione (GSH)/oxidised glutathione (GSSG) level, however the toxic effects were attenuated in the combinations of HlyA + ECT suggesting ECT-induced protection of erythrocytes from HlyA.
