What term describes the morphology of organisms that vary in shape and size? Pleomorphic Capsules are the basis of which test? Serotyping A mucoid colony on blood agar medium indicates that which of the following characteristics may be present? Organism has a capsule. What are dark staining granules called? Metachromatic Which of the following organisms are non-motile? Shigella and Klebsiella In the bacterial growth cycle, growth ceases because nutrients a...

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 ...
