“…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.…”

“…Despite a 1998 study specifically assessing the prevalence of broad-host-range phages (Jensen et al, 1998), and recent examples of such phages in Gram-positive genera (Ammann et al, 2008;Chen & Novick, 2009), the consensus remains that phage infection tends to be species and strain specific. However, other examples of broad-host-range phages have been reported (for example, see Gill et al, 2003), and such a stringent model of phage-bacterium interactions fails to explain the abundance of phages in the environment.…”

Characterization of a broad-host-range flagellum-dependent phage that mediates high-efficiency generalized transduction in, and between, Serratia and Pantoea

A phage (WOT8) isolated on Serratia sp. ATCC 39006 was shown to be flagellum-dependent, and to mediate generalized transduction with high efficiency (up to 10 "4 transductants per p.f.u.). WOT8 was shown to have a broad host range because it also infected a strain of Pantoea agglomerans isolated from the rhizosphere. Transduction of plasmid-borne antibiotic resistance between the two bacterial genera was demonstrated, consistent with purported ecological roles of phages in dissemination of genes between bacterial genera. Serratia sp. ATCC 39006 and P. agglomerans produce a number of interesting secondary metabolites that have potential applications in cancer therapy and biocontrol of fungal infections. WOT8 has utility as a powerful functional genomics tool in these bacteria.

A set of 83 lytic dairy bacteriophages (phages) infecting flavor-producing mesophilic starter strains of the Leuconostoc genus was characterized, and the first in-depth taxonomic scheme was established for this phage group. Phages were obtained from different sources, i.e., from dairy samples originating from 11 German dairies (50 Leuconostoc pseudomesenteroides [Ln. pseudomesenteroides] phages, 4 Ln. mesenteroides phages) and from 3 external phage collections (17 Ln. pseudomesenteroides phages, 12 Ln. mesenteroides phages). All phages belonged to the Siphoviridae family of phages with isometric heads (diameter, 55 nm) and noncontractile tails (length, 140 nm). With the exception of one phage (i.e., phage ⌽LN25), all Ln. mesenteroides phages lysed the same host strains and revealed characteristic globular baseplate appendages. Phage ⌽LN25, with different Y-shaped appendages, had a unique host range. Apart from two phages (i.e., phages P792 and P793), all Ln. pseudomesenteroides phages shared the same host range and had plain baseplates without distinguishable appendages. They were further characterized by the presence or absence of a collar below the phage head or by unique tails with straight striations. Phages P792 and P793 with characteristic fluffy baseplate appendages could propagate only on other specific hosts. All Ln. mesenteroides and all Ln. pseudomesenteroides phages were members of two (host species-specific) distinct genotypes but shared a limited conserved DNA region specifying their structural genes. A PCR detection system was established and was shown to be reliable for the detection of all Leuconostoc phage types.

“…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.…”

In clinical periodontal practice, patients with periodontitis frequently yield subgingival pathogens, resistant to therapeutic concentrations of commonly used antibiotics. The oral cavity is believed to provide excellent exogenous horizontal DNA transfer in dental plaque bacteria. Plasmids harness the replication, transcription, and translation systems of their host to ensure their continuity. While doing so, they burden their hosts' functionality. The non-specificity and inefficiency of current antibiotics and plasmid-mediated drug resistance is a major emerging challenge in dentistry.
