Empiric drug regimens listed for the various bacterial strains are for ADULT patients with normal renal function. Review the relevant package insert for additional prescribing information.


  • Large family of Gram-negative bacteria that includes many of the more familiar pathogens, such as Salmonella, Escherichia coli, Yersinia pestis, Klebsiella and Shigella, Proteus, Enterobacter, Serratia, and Citrobacter.
  • -Several are present in the human intestinal tract (normal part of the gut flora).
  • -Facultative anaerobes.  Most also reduce nitrate to nitrite.
  • -Many have multiple flagella (however, a few species are nonmotile).
  • -Non-spore forming.
  • -Variable catalase reactions among the species.
  • -Some strains produce highly toxic endotoxins
