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.
The adverse event profiles of the PDE5 inhibitors are generally similar (Table 3). Class-specific side effects include headache, flushing, nasal congestion, dyspepsia and myalgia, which are a reflection of vasodilatory effects on the capillary smooth muscle in other parts of the body.owever, the PDE5 inhibitors exhibit a range of specificities for the other PDE isozymes. Some differences exist in the selectivity of the PDE5 inhibitors for PDE6, an enzyme in the retina that plays an important role in the transfer of light impulses into nerve impulses.
