Many species of bacteria form variants which grow slowly on agar media and produce small or dwarf colonies that are only a few tenths of a millimeter or less in diameter. These small colony variants may be isolated directly from nature as in the case of Salmonella typhosa (Jacobsen, 1910; Morris, Barnes, and Sellers, 1943), Corynebacterium diphtheriae, and other bacteria (Morton, 1940). They ca...
Foodborne salmonellosis is still today a serious public health issue: very common in poor developing countries, due to the bad general hygiene conditions, it is also largely widespread in developed countries. In the latter, 95% of recorded clinical cases are foodborne (Liu et al., 2011). According to EFSA epidemiological data (2011), in the European Union (EU) Salmonella is the second cause of ...
