Many pathogenic bacteria exist in nature as multiple antigenic types or serotypes, meaning that they are variant strains of the same pathogenic species. For example, there are multiple serotypes of Salmonella enterica based on differences in cell wall (O) antigens and/or flagellar (H) antigens.any pathogenic bacteria exist in nature as multiple antigenic types or serotypes, meaning that they are variant strains of the same pathogenic species.

Genetically modified foods or GM foods, also genetically engineered foods, are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.he discovery of enzymes and their role in fermentation and digestion of foods led to the use of genetically modified microbes to make enzymes such as the protease chymosin for cheese production. Cheese had typically been made using the enzyme complex rennet that had extracted from cows' stomach lining.
