ABSTRACT
Salmonella is a genus belonging to the family Enterobacteriaceae. The classification of Salmonella into species is little used in epidemiological studies, with the nomenclature linked to serotyping being much better known and more widely used. The traditional detection technique used to detect Salmonella in foods is a classical culture presence/absence method, specifically developed to ensure the detection even in the most extremely unfavorable situations. The somatic antigens have their chemical basis in the diversity of the polysaccharides contained in the cell walls of the Gram-negative bacteria. The major antigens serve as a basis to separate the Salmonella strains into somatic serogroups. Flagellar antigens are derived from the flagella of motile strains. They are heat sensitive and arise from variations in the amino acid sequence of the flagellar proteins. The principal habitat of the salmonellas is the intestinal tract of humans and animals.
