Exercise 3
– The Enterobacteriaceae (Enteric Bacilli)
1. What does the term IMViC mean?
2. Why is the IMViC useful in identifying Enterobacteriaceae? Are further biochemical tests necessary
for complete identification?
3. What diagnostic test differentiates Proteus and Providencia species from other Enterobacteriaceae?
4. How is E. coli distinguished from P. vulgaris on MacConkey agar? On a TSI slant?
5. Why is it important to differentiate glucose nonfermenters from Enterobacteriaceae
