Salmonella enterica subspecies enterica serovar Enteritidis (S. Enteritidis) has been recently recognized as a prevalent cause of alimentary toxi-infection worldwide. Its widespread presence could be explained by intensification and globalization of traffic, global trade, and the rest of socioeconomic processes. However, no matter to global spreading of S.

Salmonella is considered as a cause of various diseases from acute enterocolitis to typhoid fever.
