Bacterial Competition Influences the Ability of Symbiotic Bacteria to Colonize Western Flower Thrips [PDF]

Frontiers in Microbiology, 2022
Symbiont mediated RNAi (SMR) is a promising method for precision control of pest insect species such as Western Flower Thrips (WFT). Two species of bacteria are known to be dominant symbiotic bacteria in WFT, namely BFo1 and BFo2 (Bacteria from ...

A pyocin-like T6SS effector mediates bacterial competition in Yersinia pseudotuberculosis [PDF]

Microbiology Spectrum
Within the realm of Gram-negative bacteria, bacteriocins are secreted almost everywhere, and the most representative are colicin and pyocin, which are secreted by Escherichia coli and Pseudomonas aeruginosa, respectively.

Widespread fungal-bacterial competition for magnesium lowers bacterial susceptibility to polymyxin antibiotics. [PDF]

PLoS Biology
Fungi and bacteria coexist in many polymicrobial communities, yet the molecular basis of their interactions remains poorly understood. Here, we show that the fungus Candida albicans sequesters essential magnesium ions from the bacterium Pseudomonas ...

The Impact of Type VI Secretion System, Bacteriocins and Antibiotics on Bacterial Competition of Pectobacterium carotovorum subsp. brasiliense and the Regulation of Carbapenem Biosynthesis by Iron and the Ferric-Uptake Regulator [PDF]

Frontiers in Microbiology, 2019
The complexity of plant microbial communities provides a rich model for investigating biochemical and regulatory strategies involved in interbacterial competition. Within these niches, the soft rot Enterobacteriaceae (SRE) represents an emerging group of

The T6SS-Dependent Effector Re78 of Rhizobium etli Mim1 Benefits Bacterial Competition [PDF]

Biology, 2023
The genes of the type VI secretion system (T6SS) from Rhizobium etli Mim1 (ReMim1) that contain possible effectors can be divided into three modules. The mutants in them indicated that they are not required for effective nodulation with beans. To analyze

Bacterial Competition Systems Share a Domain Required for Inner Membrane Transport of the Bacteriocin Pyocin G from Pseudomonas aeruginosa [PDF]

mBio, 2022
Bacteria exploit a variety of attack strategies to gain dominance within ecological niches. Prominent among these are contact-dependent inhibition (CDI), type VI secretion (T6SS), and bacteriocins.

A toxic effector of T7SS facilitates bacterial competition and virulence through membrane damage in Streptococcus suis [PDF]

Veterinary Research
Streptococcus suis is a zoonotic pathogen that poses a significant threat to both the swine industry and human health. This bacterium utilizes a type VII secretion system (T7SS) to translocate effector proteins that mediate bacterial competition and ...
