Abstract

Salmonella is a genus of bacteria that is a major cause of food borne illness throughout the world. Species of Salmonella like S. thyphimurium and S. enteriditis still pose significant health problems. Poultry and egg products are the main food sources infected by these species (Portrait et al. 1999). The main problem with these infections is their rapid spread among the infected species (in a flock). An infected bird (which has Salmonella infection in its intestinal tract) or a flock of birds can transfer the infection to others rapidly even before the appearance of symptoms and thus the urgency of the situation is not known until many birds are infected, leading to huge losses in processing these animals, or significant problems for poultry farms. There have been efforts like vaccination of chickens and turkeys, antibiotic treatment or competitive expulsion by harmless bacteria, but complete elimination or control of the problems is yet to be achieved (Nava et al. 2005).
