Bacteria

Definition

Bacteria are organisms that consist of a single cell without a nucleus and with distinct structural, physiological and evolutionary characteristics. Bacteria form one of the three domains of life; the others are archaea and eukaryotes. Bacterial species and their habitats exhibit great diversity.

    D-glutamate is an essential component of the bacterial cell wall. Here, the authors use mouse models of infection with Acinetobacter baumannii, Pseudomonas aeruginosa and Staphylococcus aureus to show that bacterial mutants unable to synthesize D-glutamate can potentially be used as live attenuated vaccines.

    Elizabethkingia anophelis is an emerging pathogen of high antimicrobial resistance. Perrin and colleagues sequenced isolates of a 2015/2016 E. anophelis outbreak in Wisconsin and found substantial genetic diversity, accelerated evolutionary rate and a disruptive mutation in the DNA repair gene mutY.

    When faced with hypoxic conditions, Mycobacterium tuberculosis adapts its metabolism to generate intermediates reserved for re-initiation of peptidoglycan biosynthesis that can be used as soon as it is re-exposed to normoxia.

    Many bacteria can infect and persist inside their hosts for long periods of time. In this Review, Fisher, Gollan and Helaine discuss recent developments in our understanding of bacterial persisters and their potential implications for the treatment of persistent infections.
