SOD1 and brucellosis: Recent vaccine candidates against brucellosis have shown promising results, including DNA vaccines encoding genes for lumazine synthase (BLS) (14), Cu/Zn superoxide dismutase (SOD) protein (15), and various open reading frames (ORFs) such as BAB1_0267, BAB1_0270, BAB1_0278, BAB1_0278a, as well as a multiepitope DNA vaccine designed using immunoinformatic approaches (16).
