If a bond has a 7% nominal yield or coupon and was purchased at a premium of $103 ($1030), then your YTM will calculate lower because the 7% interest is only paid to the $1000 par. The $30 premium does not earn interest and is not redeemable at par. So, a 7% bond at a premium is not really yielding 7% in that example.

A common subdivision system of E. coli, but not based on evolutionary relatedness, is by serotype, which is based on major surface antigens (O antigen: part of lipopolysaccharide layer; H: flagellin; K antigen: capsule), e.g. O157:H7). It is, however, common to cite only the serogroup, i.e. the O-antigen.
