Targeting antibiotic resistant bacteria with phage reduces bacterial density in an insect host
Phage therapy is attracting growing interest among clinicians as antibiotic resistance continues becoming harder to control. However, clinical trials and animal model studies on bacteriophage treatment are still scarce and results on the efficacy vary. Recent research suggests that using traditional antimicrobials in concert with phage could have desirable synergistic effects that hinder the evolution of resistance. Here, we present a novel insect gut model to study phage–antibiotic interaction in a system where antibiotic resistance initially exists in very low frequency and phage specifically targets the resistance bearing cells. We demonstrate that while phage therapy could not reduce th…
Genetic and Biochemical Characterization of Field-Evolved Resistance to Bacillus thuringiensis Toxin Cry1Ac in the Diamondback Moth, Plutella xylostella
ABSTRACT The long-term usefulness of Bacillus thuringiensis Cry toxins, either in sprays or in transgenic crops, may be compromised by the evolution of resistance in target insects. Managing the evolution of resistance to B. thuringiensis toxins requires extensive knowledge about the mechanisms, genetics, and ecology of resistance genes. To date, laboratory-selected populations have provided information on the diverse genetics and mechanisms of resistance to B. thuringiensis , highly resistant field populations being rare. However, the selection pressures on field and laboratory populations are very different and may produce resistance genes with distinct characteristics. In order to better…

Biogeographic Atlas of the Southern Ocean.
498 pages; International audience; The Southern Ocean waters to the west of the Antarctic Peninsula are warming faster than almost any other place on Earth. This area of most rapid environmental change was among others targeted by the Census of Antarctic Marine Life in its collection of biogeographic information. Such biogeographic information is of fundamental importance for monitoring biodiversity, discovering biodiversity hotspots, defining ecoregions and detecting the impacts of environmental changes. It is the preliminary and necessary step in designing marine protected areas in a changing ocean. At the end of five years of extensive biodiversity exploration and assessment by CAML (www…
