Abstract
OBJECTIVE: To determine the role of PPE25 in the infection of
METHODS: In MS-ppe25 group, PPE25 was expressed in non-pathogenic fast-growing
RESULTS: PPE25 protein had no effect on MS growth, colony formation and the size of single colonies. MS-infected PMN had higher percentages of CFU and LDH release 2, 6, and 12 h after infections compared with the MS-vec group (
CONCLUSIONS: PPE25 protein increases the survival of MS in PMN, induces cell necrosis, inhibits the expressions of ROS and NO, and changes the secretion of cytokines, which helps spread of the pathogen by evading host immunity.
