Table 4. Transducing titers (c.f.u./ml) for infections of SaPI-containing strains by phages 80α, φNM1 and φNM2. Numbers for ST1 are an average of three technical replicates.

	Infecting phage
Recipient strain	80α	φNM1	φNM2
ST1 (SaPI1)	2.7 × 108 (1)*	2.0 × 109 (7.4)	6.0 × 108 (2.2)
ST137 (SaPIbov1)	1.9 × 108 (1)	3.4 × 108 (1.8)	3.2 × 108 (1.7)

^*Numbers in parentheses were normalized to 80α for each SaPI.
