Review Sheet Week 7
Exercise 24.1
Questions
- What does the term IMViC mean?
 - Why is the IMViC useful in identifying
 
- Enterobacteriaceae? Are further biochemical tests necessary for complete identification?
 - What diagnostic test differentiates
 - ProteusandProvidenciaspecies from otherEnterobacteriaceae?
 - How is
 - E. colidistinguished fromP. vulgarison MacConkey agar? On a TSI slant?
 - Instead of TSI, why would a slant medium containing only dextrose and lactose (not sucrose) be preferable for detecting

 - What procedures, other than biochemical, are used to identify microorganisms?
 - What is the purpose of the control test run in parallel with bacterial agglutination?

 - Describe two mechanisms by which
 - E. colican produce disease.
 - What is meant by the term “enteric pathogen”?
