Salmonella - Classification, Causes, Microscopy, Treatment, …
Salmonella includes a group of gram-negative bacillus bacteria that causes food poisoning and the consequent infection of the intestinal tract. While some of the infections can be easily treated, some of the strains have been shown to resist antibiotic treatment.
Serotypes and the Importance of Serotyping Salmonella
For instance, Salmonella bacteria look alike under the microscope but can be separated into many serotypes based on two structures on their surface: The outermost portion of the bacteria’s surface covering, called the O antigen; and; A slender threadlike structure, called the H antigen, that is part of the flagella.
