12 de jun. de 2024 · These studies establish a new paradigm by which a bacterial pore is assembled, show that a distant phylogenetic branch of the CDCs kills bacteria rather than eukaryotic cells, and reveal genes...
12 de jun. de 2024 · Bacteria that produce toxins such as colicins and tailocins, which are only released upon cell lysis, are examples where the population must strike a balance between the need to protect against competition while also minimizing the cost of autolysis.
12 de jun. de 2024 · In vitro antagonistic assay between rhizobacteria strains (AS1-AS21) and Rhizoctonia solani f. sp. sasakii by dual-culture assays on PDA medium 7 days after incubation.
12 de jun. de 2024 · Antibiotic resistance (AMR) is a global public health threat, challenging the effectiveness of antibiotics in combating bacterial infections. AMR also represents one of the most crucial survival traits evolved by bacteria. Antibiotics emerged hundreds of millions of years ago as advantageous secondary metabolites produced by microbes.
14 de jun. de 2024 · In most bacterial type IV pili, the antagonist actions of two conserved ATPases, PilB and PilT, form the basis of pili dynamics. While PilB promotes fiber assembly, ATP hydrolysis by PilT fuels...
12 de jun. de 2024 · Most bacteria live in communities, often with closely related strains and species with whom they must compete for space and resources. Consequently, bacteria have acquired or evolved mechanisms to antagonize competitors through the production of antibacterial toxins.
12 de jun. de 2024 · Protection against antibacterial toxins can be acquired by horizontal gene transfer, receptor or target alteration, induction of protective functions, physical barriers, and other diverse processes. Here, we review recent studies in this rapidly expanding field.
