Particular groups of plant-beneficial fluorescent pseudomonads are not only root colonizers that provide plant disease suppression, but in addition are able to infect and kill insect larvae. The mechanisms by which the bacteria manage to infest this alternative host, to overcome its immune system, and to ultimately kill the insect are still largely unknown. However, the investigation of the few...

Pseudomonas fluorescens is a genetically and phenotypically heterogeneous species that is often reported as a spoiler of fresh foods, but it has recently been implicated in clinical infection. In this study, we sequenced the genome of P. fluorescens strain ITEM 17298, isolated from mozzarella cheese and able to cause several alterations under cold storage.

We report the draft genomes of five Pseudomonas fluorescens strains, isolated from clinical samples. Phylogenetic analysis places three in subclade I and two in subclade II of the P. fluorescens species complex. The average G+C content and genomic size are 63% and 7.1 Mbp (subclade I) and 59.6% and 6.14 Mbp (subclade II), respectively.

In most environments many microorganisms live in close vicinity and can interact in various ways. Recent studies suggest that bacteria are able to sense and respond to the presence of neighbouring bacteria in the environment and alter their response accordingly. This ability might be an important strategy in complex habitats such as soils, with great implications for shaping the microbial commu...
