ABSTRACTThe diversity ofPseudomonas aeruginosabacteriophages was investigated using a collection of 68 phages isolated from Central Mexico. Most of the phages carried double-stranded DNA (dsDNA) genomes and were classified into 12 species. Comparison of the genomes of selected archetypal phages with extant sequences in GenBank resulted in the identification of six novel species. This finding increased the group diversity by ∼30%. The great diversity of phage species could be related to the ubiquitous nature ofP. aeruginosa.

“…Brüssow and Desiere (2001) suggested that S. thermophilus phages differing in host range have completely unrelated variable regions, whereas those with overlapping host ranges share highly related variable regions. Recent results (Binetti et al, 2005;Guglielmotti, Binetti, Reinheimer, & Quiberoni, 2009a) indicate that additional phage and host factors (such as resistance mechanisms) could be involved in the host specificity of these phages, as previously proposed by other authors (Duplessis & Moineau, 2001;Duplessis, Lévesque, & Moineau, 2006;Sturino & Klaenhammer, 2006). It is worth mentioning that no phage receptors at the host cell surface are known in S. thermophilus.…”

Lysogeny entails more economical and technological risks in probiotic Lactobacillus casei/paracasei bacteria than in other lactic acid bacteria, due to economic value. Lysogeny is widely spread among L. casei/paracasei strains. Siphophages CL1 and CL2, isolated from noninfected lysed‐cultures of commercial L. paracasei A, are thermoresistant, have identical host spectrum, latent and burst times, whereas burst sizes are 148 and 85, respectively. Mitomycin C induction of L. paracasei A yielded prophage iA2, whose presence was confirmed on the strain genome and whose restriction patterns differed from phages CL1 and CL2. The latter shared several restriction fragments, probably indicating a common origin.
