TABLE 2.
Adsorption deficiency of phage-resistant mutants and their transductants
| Organism | Phage A118 adsorption (PFU ml−1)a |
|---|---|
| Parent strain 1/2a3 | 7 × 104 |
| Mutant HLT2 | 1.2 × 108 |
| Transductant HLT2/1 | >1.2 × 108 |
| Mutant HLT8 | 2.2 × 107 |
| Transductant HLT8/2 | 5.7 × 107 |
a
Adsorption of A118 was measured by determining the number of PFU remaining in the supernatant of a mixture containing A118 and the indicated strain, as described in the text. HLT2/1 and HLT8/2 are transductants obtained from HLT2 and HLT8, respectively. Similar results were obtained with two other transductants from each mutant.
