Following the pioneering work of Wilson [4], the perturbative renormalization in QED has been studied both in LFD [5–7] and CLFD [8]. In these papers the fermion self-energy

Strains belonging to serotype 1 (GPE PC73, Xa23R1 and MUS 060) share the same LPS locus: LPS1, whereas the strain belonging to serotype 3 (GPE 39) exhibits another LPS locus:

coli, no additional secretion function is required and thus the energy source driving translocation across the outer membrane is derived from the correct folding of the passenger
