Amino acid sequence alignment of the C-terminal domain of both EhSWP1a (A) and EhSWP1b (B) from four E. hellem human isolates. The sequence encoding the C-terminal region of EhSWP1a and EhSWP1b was amplified using primers EhD3 and EhR4 (Fig. 2), cloned in the pGEM-T Easy vector (Promega), and sequenced. Changes in amino acids for isolate V213 are shaded in gray. The 26 aa specific to EhSWP1b are underlined. Amino acids are numbered on the right.
