Interbacterial Competition in the Burkholderia cepacia Complex [PDF]
, 2020 Bacteria often live in multicellular communities composed of multiple species. Bacteria interact with one another during intimate cell-cell contact within such environments, and these interactions influence the ecology and evolution of multicellular communities.

Deadly syringes: type VI secretion system activities in pathogenicity and interbacterial competition
Current Opinion in Microbiology, 2013Among specialized bacterial secretion systems, the most widespread is the type VI secretion system (T6SS). This transports effector molecules into target cells in a single, cell-contact dependent step. T6SSs are structurally related to the cell-puncturing device of tailed bacteriophages and predicted to function as contractile injection machineries ...

The impact of a putative lipase, TleVf1, on interbacterial competition in Vibrio fischeri
Interbacterial competition occurs when multiple bacteria have the ability to fulfill the same ecological niche. Vibrio fischeri is a marine bacterium that establishes a multistrain symbiosis with the Hawaiian bobtail squid, where different strains engage in competition as they colonize the light organ. One mechanism that enables this competition during

Interbacterial competition assays have become an essential tool for understanding the interactions between bacteria and their ability to outcompete one another in natural environments. This is especially relevant when studying the type VI secretion system (T6SS), a contact-dependent bacterial weapon that can be used to kill or inhibit the growth of ...

Contact-dependent antibacterial mechanisms enhance bacterial fitness as they enable bacteria to outcompete their rivals and thrive in diverse environments. Such systems also allow pathogenic bacteria to establish a niche inside a host, where they must compete with commensal microflora.

Interbacterial Biofilm Competition through a Suite of Secreted Metabolites
ACS Chemical BiologyPolymicrobial biofilms are ubiquitous, and the complex interspecies interactions within them are cryptic. We discovered the chemical foundation of antagonistic interactions in a model dual-species biofilm in which Pseudomonas aeruginosa inhibits the biofilm formation of Agrobacterium tumefaciens. Three known siderophores produced by P.

A small microcin plays a big role in V. cholerae interbacterial competition
Cell Host & MicrobeMicrocins are antibacterial small proteins secreted by gram-negative bacteria. In this issue of Cell Host & Microbe, Kim et al. report the discovery of a V. cholerae microcin, MvcC. MvcC shows antibacterial activity against non-self V. cholerae strains, which do not encode the cognate immunity protein.

The Agrobacterium Type VI Secretion System: A Contractile Nanomachine for Interbacterial Competition
2018The bacterial type VI secretion system (T6SS) is a contractile nanomachine dedicated to delivering molecules out of bacterial cells. T6SS-encoding loci are in the genome sequences of many Gram-negative bacteria, and T6SS has been implicated in a plethora of roles.
