TABLE 1.
CuZnSOD activity (potassium cyanide or DEDC inhibitable) and hybridization of Haemophilus sodC probes to chromosomal DNA
| Strain (no. of isolates) | Phylogenetic divisiona | Hybridization to sodC probeb | CuZnSOD activityb |
|---|---|---|---|
| Noncapsulate ET (45) | NA | − | − |
| Serotype a (2) | I | − | − |
| Serotype a (3) | II | + | − |
| Serotype b (5) | II | + | − |
| Serotype e (6) | * | + | − |
| Serotype f (6) | II | + | − |
| Cryptic genospecies (12) | NA | + | + |
a
I and II correspond to phylogenetic divisions I and II, respectively, of capsulate H. influenzae (11). NA, not applicable; *, distantly related to division I and II strains.
b
+ and −, positive and negative, respectively, for probe hybridization or CuZnSOD activity.
