  2. 1. Too close for comfort : The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation

    Author : Marcus Wäneskog; Sanna Koskiniemi; Paul Rainey; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial interactions; cell-cell binding; contact-dependent growth inhibition; CDI; CdiB; CdiA; CdiI; outer-membrane receptor; BamA; OmpC; OmpF; extracellular toxin delivery; Toxin-Antitoxin; TA-system; persister cells; stress tolerance; stress response; rpoS; rssB; quorum sensing; multicellular behavior; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. READ MORE

  4. 2. The effects of internally expressed Contact-Dependent growth Inhibition (CDI) toxins in bacteria

    Author : Magnus Stårsta; Sanna Koskiniemi; Pierre Genevaux; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Bacteria, both pathogenic and non-pathogenic, have developed multiple forms of competition mechanisms to combat each other including, but not limited to, Contact-Dependent growth Inhibition (CDI) systems, Type VI Secretion Systems and the associated Rearrangement hotspot (Rhs) toxin system. These systems usually confers a great fitness advantage as they allow for precise delivery of toxic molecules into competing bacteria whilst sister cells are protected from auto-inhibition by producing a cognate immunity protein.

  5. 3. To defend or to offend? : Bacterial defence and competition systems

    Author : Danna Lee; Sanna Koskiniemi; Marjan van der Woude; Uppsala universitet; []
    Keywords : bacterial defence systems; bacterial competition systems; toxin-antitoxin systems; colicin; contact-dependent growth inhibition CDI ; type VI secretion system T6SS ; Rearrangement hotspot Rhs proteins; CRISPR; horizontal gene transfer; antibiotic resistance; Salmonella; Enterotoxigenic E. coli ETEC ; probiotics; synthetic biology.;

    Abstract : Bacteria are prokaryotic microorganisms that can be found in all niches of the biosphere. Bacteria must constantly evolve in order to survive and adapt to their environments. Defence systems and competition systems play a vital role in ensuring the survival of bacteria. READ MORE
