    In settings with limited resources and a wide range of possible etiologies, molecular technologies offer an effective solution for infectious disease diagnostics, because they are agile, fast and flexible. Health systems that routinely use molecular diagnostics will achieve economies of scale, maximize limited expertize and rapidly respond to new threats.

Research Highlights

  • In Brief |

    In marine sponges, higher microbiome diversity and maintenance of host innate immunity was associated with resilience to warming and acidification.

    • Ursula Hofer
  • In Brief |

    This study shows that phage predation of Klebsiella pneumoniae is regulated by capsule type and that capsule loss promotes plasmid conjugation.

    • Ursula Hofer
  • Research Highlight |

    This study reports that bacteriocins are encoded in temperate phages, and that they can be transferred between bacterial hosts, which provides a competitive advantage.

    • Andrea Du Toit
  • In Brief |

    A recent study uncovers that sensing of host amino acids in Aeromonas veronii regulates bacterial motility, enhancing gut colonization of zebrafish.

  • Review Article |

    In this Review, Mizrahi and colleagues describe the composition, ecology and metabolism of the rumen microbiome, and the impact on host physiology and the environment. They also discuss the most pertinent methane mitigation strategies that emerged to balance food security and environmental impact.

  • Review Article |

    Type VII secretion systems have a key role in the secretion of effector proteins in non-pathogenic mycobacteria and pathogenic mycobacteria such as Mycobacterium tuberculosis. In this Review, Rivera-Calzada et al. provide an overview of the architecture of type VII secretion systems, their functions and transport models.
