Bacterial genetics

Bacterial genetics is the study of the mechanisms of heritable information in bacteria, their chromosomes, plasmids, transposons and phages. Techniques that have enabled this discipline are culture in defined media, replica plating, mutagenesis, transformation, conjugation and transduction.

    Widespread use of antibiotics in animals either as growth promoters or for metaphylaxis may drive the spread of clinically relevant drug resistance genes and pathogens. New work uncovers drug resistance gene patterns from livestock across European farms and finds a correlation with agricultural antibiotic use.

    Although the spotlight on CRISPR–Cas systems has shone on their immense potential as genome-editing tools, the field’s origins are rooted in the microbiology of phage–bacterium interactions. Furthering our understanding of these processes can uncover more systems and generate new reagents with revolutionary properties.

    Genetic integration of a humanized chemotaxis receptor unexpectedly reveals that a widely expressed immune protein is targeted by Staphylococcus aureus Panton–Valentine leukocidin in a novel way, changing our fundamental understanding of toxin–receptor biology and host–pathogen interaction.

    Bacteria encode many strategies to prevent or escape infection. Through the analysis of metagenomic dark matter, several novel defence systems were identified, some of which were engineered and characterized in vivo, showing that they provide resistance against viruses and plasmids.
