Plasmid Transfer via Transduction from Streptococcus thermophilus to Lactococcus lactis

Abstract: Using Streptococcus thermophilus phages, plasmid transduction in Lactococcus lactis was demonstrated. The transduction frequencies were 4 orders of magnitude lower in L. lactis than in S. thermophilus. These results are the first evidence that there is phage-mediated direct transfer of DNA from S. thermophilus to L. lactis. The implications of these results for phage evolution are discussed.

“…However, there are wider ecological implications, and incorporation of new DNA into a bacterial host may have more subtle effects than the acquisition of toxin genes. The results presented here underscore similar findings in Gram-positive strains that have been published recently (Ammann et al, 2008;Chen & Novick, 2009). …”

“…However, marked differences are sometimes seen with broad-host-range transducing phages. For example, three transducing phages that each infect both Streptococcus thermophilus and Lactococcus lactis displayed transduction efficiencies that were four orders of magnitude lower in L. lactis compared with those in S. thermophilus, and this was explained by the weak absorption of the phage to L. lactis (Ammann et al, 2008). The lower transduction efficiencies seen in P. agglomerans compared with Serratia 39006 may be a consequence of less avid adsorption of WOT8 to P. agglomerans.…”

“…Transduction, similar to transformation except that, the exogenous bacterial DNA carrying resistance determinant is transferred by a phage particle (Ammann et al (2008). Studies on saliva have isolated bacteriophages with a) bactericidal effect against specific bacterial pathogens such as Enterococcus faecalis, for example (Stevens et al 2009) and b) transduction property capable of transferring antibiotic resistance genes.…”
