- ABSTRACT
- (i) Relaxed selection for prototrophy.
- (ii) Conditional auxotrophy.
- (iii) Selection for auxotrophy.
- (iv) Mutation pressure.
- Auxotrophy of serovar Dublin isolates.
- Reversion tests.
- Initial evidence for a nadA mutation.
- The serovar Dublin nadA allele is necessary and sufficient for auxotrophy.
- Comparing nadA sequences of enteric bacteria.
- A search for conditions that suppress the auxotrophy of serovar Dublin.
- Pyridine limitation does not provide antibiotic resistance in serovar Dublin.
- Frequency of Nad auxotrophs in natural isolates of S. enterica and E. coli.
- Natural auxotrophy is not associated with mutators or hot spots.
