Salmonella enterica enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella.[1] Many of the pathogenic serovars of the S. enterica species are in this subspecies.[2]

Serovars (not an all-inclusive list, as there are >2,500)

  • Salmonella Choleraesuis
  • Salmonella Dublin
  • Salmonella Enteritidis
  • Salmonella Gallinarum
  • Salmonella Hadar
  • Salmonella Heidelberg
  • Salmonella Infantis
  • Salmonella Paratyphi
  • Salmonella Typhi
  • Salmonella Typhimurium

Nomenclature

The serovars can be designated fully or in a shortened form.[3] The short form lists the genus, Salmonella, which is followed by the capitalized and non-italicized serovar. The full designation for Salmonella Typhi is Salmonella enterica enterica, serovar Typhi. Each serovar can have many strains as well, which allows for a rapid increase in the total number of antigenically variable bacteria.[4]

Treatment(if caught by bacterium)

Fluids and electrolytes may be given through a vein (intravenously), or you may be asked to drink uncontaminated water with electrolyte packets.

Appropriate antibiotics, such as ceftriaxone, are given to kill the bacteria. But,it has also been suggested that azithromycin is better at treating typhoid in resistant populations than both fluoroquinolone drugs and ceftriaxone. There are increasing rates of antibiotic resistance throughout the world, so your health care provider will check current recommendations before choosing an antibiotic.
