Isolation and sequencing of a temperate transducing phage for Pasteurella multocida

Article Abstract:

A temperate bacteriophage (F108) obtained from a Pasteurella multocida serogroup A isolate, which is able to carry out generalized transduction, is characterized and sequenced. The absence of pathogenic factors in its genome is shown by both in silico and in vivo experimental methods, suggesting that bacteriophage F108 might be a suitable genetic tool for P. multocida serogroup A strains.

Large variabilities in host susceptibility and phage host range govern interactions between lytic marine phages and their Flavobacterium hosts

Article Abstract:

Studies have shown that for a marine phage-host assemblage, the interactions are complex and specificity and efficiency of infection and lysis are highly variable among phages infectious to strains of the same bacterial species. The marine bacterioplankton are shown to be susceptible to multiple co-occurring phages and the sensitivity towards phage infection is strain specific.

Impact of phages on two-species bacterial communities

Article Abstract:

The impact of phages attacking one species in a two-species culture of bacteria is investigated. Results suggest that phages can sometimes, although not always, provide long-term suppression of target bacteria.
