Identification of immunogenic antigens and evaluation of vaccine candidates against Clostridium perfringens.

ABSTRACT: Necrotic enteritis (NE) caused by Clostridium perfringens (C. perfringens) has resulted in significant losses for the poultry industry worldwide. Currently, there is no widely promoted vaccine for NE. In this study, immunoprecipitation (IP) was employed to isolate immunogenic proteins of C. perfringens, and 118 potential candidate antigens were identified through liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). From these, three candidate antigen proteins were selected based on their predicted antigenicity, hydrophilicity, stability, and transmembrane signalling properties: ArcB (an ornithine aminotransferase), TmpC (a probable membrane lipoprotein), and EntB (a possible enterotoxin). These three proteins were successfully produced in large quantities using Escherichia
