Salmonella typhi is the Gram negative bacteria that have the ability to infect humans via transferring an effector protein into host cells through type III secretion system. This effector protein starts interfering various host mechanisms which helps in bacterial survival. Antibiotics activate the immune system against infection but sometimes bacteria develop resistance by modulating its mechanism. The present study was carried out to explore an uncharacterized gene which may be involved in infection enhancement. | In silico analysis for functional predicition of salmonella typhi gene in human infection through threading model
