| Abstract: | Oxidant sensitivity was investigated in erythrocytes from Barrow Island euro (Macropus robustus isabellinus), mainland euro (Macropus robustus erubescens) and brushtailed-bettong (Bettongia pericillata). Oxidant sensitivity was tested by measuring methaemoglobin formation in haemolysates treated with H2O2 or NaNO2. Barrow Island euro produced the highest methaemoglobin formation with H2O2. There was a significant negative correlation between catalase activity and H2O2-induced methaemoglobin formation. Our results provide further evidence supporting previous findings on eight species of marsupials. |
