Shiga toxin-producing E. coli(STEC), also called verotoxinogenic E. coli, usually do not cause disease inanimals but may cause watery diarrhoea, haemorrhagic colitis, and/orhaemolytic uraemic syndrome in humans. Zoonotic STEC include the O157:H7strains and, with increasing frequency, certain non-O157 strains.
Increased heart rate was due to predominance of the cardiac sympathetic over the cardiac vagal activation. In spite of a marked reflex increase in the renal and cardiac sympathetic nerve activities, the local vasodilator effect of hypoxia prevented consistent changes in arterial blood pressure.utonomic nerve and cardiovascular responses to changing blood oxygen and carbon dioxide levels in the rat.
