A; Animals serve as a reservoir of infection" is the correct answer because Shigella only infects humans while Salmonella is found in many animals. Both have diarrhea as the major symptom. Endotoxin is produced by all gram negative bacteria and exotoxin is only produced by Shigella. A major difference between Salmonella enterica and Shigella infections is that only in salmonellosis can: A. animals serve as a reservoir of infection B. diarrhea become the major symptom C. endotoxin play a ...

TSI correct answer: Triple Sugar Iron Yellow= acid production or fermentation of the sugars in the slant or butt. Gas production= indicated by the agar lifting up or breaking Red= negative or uninoculated Black= H2S production due to FeS precipitation (think salmonella or proteus) The source of Sulfur for H2S production by bacteria is the amino acid Cysteine TSI additional correct answer: Triple Sugar-Iron agar slants. is a differential medium containing 3 sugars called glucose...
