Type 1 fimbriae-mediated collective protection against type 6 secretion system attacks [PDF]
mBioBacterial competition may rely on secretion systems such as the type 6 secretion system (T6SS), which punctures and releases toxic molecules into neighboring cells.

Neisseria subflava Type 6 Secretion System competition with bacterial and fungal species [PDF]
Applied Microbiology and BiotechnologyThe aim of this study was to assess whether a Type VI Secretion System (T6SS) present in the commensal, non-pathogenic Neisseria subflava strain KU1003-01 plays a role in competition between these bacteria and other commensal and pathogenic Gram-negative

Yersinia pestis BipA is a novel regulator of pesticin and a type 6 secretion system [PDF]
Infection and ImmunityYersinia pestis is a gram-negative bacterium and the causative agent of bubonic, septicemic, and pneumonic plague. Y. pestis is most commonly transmitted to humans by infected fleas that deposit the bacteria into the dermis at the bite site, leading to ...

Role of the type 6 secretion system on apoptosis and macrophage polarization during Burkholderia pseudomallei infection. [PDF]
PLoS Neglected Tropical DiseasesBurkholderia pseudomallei (Bpm) is the causative agent of the disease melioidosis. As a facultative intracellular pathogen, Bpm has a complex lifestyle that culminates in cell-to-cell fusion and multinucleated giant cells (MNGCs) formation. The virulence

A type 6 secretion system (T6SS) encoded gene within Salmonella enterica serovar Enteritidis contributes to virulence [PDF]
Virulence, 2018 Bacteria interact with their host through protein secretion systems and surface structures. Pathogenic bacteria encode protein secretion systems that promote the invasion of the host's tissue, the evasion of the host's immune response, the thwarting ...

Identification of Virulence Genes Associated with Pathogenicity of Translocating Escherichia coli with Special Reference to the Type 6 Secretion System [PDF]
MicroorganismsRecent genomic characterisation of translocating Escherichia coli HMLN-1 isolated from mesenteric lymph nodes (MLNs) and blood of a patient with a fatal case of pancreatitis revealed the presence of a type 6 secretion system (T6SS) that was not present ...

Multiplicity of type 6 secretion system toxins limits the evolution of resistance [PDF]
Proceedings of the National Academy of SciencesThe bacterial type 6 secretion system (T6SS) is a toxin-injecting nanoweapon that mediates competition in plant- and animal-associated microbial communities. Bacteria can evolve de novo resistance against T6SS attacks, but resistance is far from universal in natural communities, suggesting key features of T6SS weaponry may act to ...

Type 6 Secretion System–Mediated Immunity to Type 4 Secretion System–Mediated Gene Transfer [PDF]
Science, 2013 Bacterial Détente? Type VI secretion systems (T6SS) correspond to dynamic intracellular organelles that are functionally analogous to contractile bacteriophage tails. The T6SS of several bacteria species have been found to be responsible for antagonistic behavior that likely reflects the translocation of toxic ...

From Wall to Wall: How the Type 6 Secretion System Knows To Stop Growing [PDF]
Journal of Bacteriology, 2019 There is an inseverable link between the size of a cell and the size of its subcellular components. The type 6 secretion system (T6SS) is no exception. In this issue, Stietz et al. report their analysis of the T6SS under conditions in which the cell size was altered to an extreme degree (M. S. Stietz, X. Liang, M. Wong, S. Hersch, and T. G.

Xenorhabdus bovienii strain jolietti uses a type 6 secretion system to kill closely related Xenorhabdus strains [PDF]
FEMS Microbiology Ecology, 2020 ABSTRACTXenorhabdus bovienii strain jolietti (XBJ) is a Gram-negative bacterium that interacts with several organisms as a part of its life cycle. It is a beneficial symbiont of nematodes, a potent pathogen of a wide range of soil-dwelling insects and also has the ability to kill soil- and insect-associated microbes.
