a Typical two-dimensional electrophoresis (2-DE) gel of Trichinella pseudospiralis adult worms excretory-secretory proteins separated in the first dimension in the pH range 4–7 and then in the second dimension on a 12% non-linear gradient polyacrylamide gel. The 2-DE gel was stained with coomassie brilliant blue G-250. Peptide spots selected for analysis are numbered. b Western blot of adult worms excretory-secretory proteins probed with pig infection sera at 26 days post-infection. Peptide spots selected for analysis are numbered. c Western blot of adult worms excretory-secretory probed with normal pig sera
