Mismatch repair in Gram-positive bacteria [PDF]
Research in Microbiology, 2016 DNA mismatch repair (MMR) is responsible for correcting errors formed during DNA replication. DNA polymerase errors include base mismatches and extra helical nucleotides referred to as insertion and deletion loops. In bacteria, MMR increases the fidelity of the chromosomal DNA replication pathway approximately 100-fold.

Role of the cell-wall structure in the retention of bacteria by microfiltration membranes [PDF]
, 2009 This experimental study investigates the retention of bacteria by porous membranes. The transfer of bacteria larger than the nominal pore size of microfiltration track-etched membranes has been studied for several kinds of bacterial strains.

Mobile Oxazolidinone Resistance Genes in Gram-Positive and Gram-Negative Bacteria
Clinical Microbiology Reviews, 2021 Seven mobile oxazolidinone resistance genes, including cfr, cfr(B), cfr(C), cfr(D), cfr(E), optrA, and poxtA, have been identified to date. The cfr genes code for 23S rRNA methylases, which confer a multiresistance phenotype that includes resistance to ...

Human platelet activation by Escherichia coli: roles for FcγRIIA and integrin αIIbβ3 [PDF]
, 2016 Gram-negative Escherichia coli cause diseases such as sepsis and hemolytic uremic syndrome in which thrombotic disorders can be found. Direct platelet–bacterium interactions might contribute to some of these conditions; however, mechanisms of human ...

Rectification of Swimming Bacteria and Self Driven Particle Systems by Arrays of Asymmetric Barriers [PDF]
Phys. Rev. Lett. 101, 018102 (2008), 2007 We show that the recent experimental observation of the rectification of swimming bacteria in a system with an array of asymmetric barriers occurs due to the ballistic component of the bacteria trajectories introduced by the bacterial "motor." Each bacteria selects a random direction for motion and then moves in this direction for a fixed period of ...

A Novel, Time-effective Approach for Capturing Bacteria from Contaminated Urine Samples [PDF]
arXiv, 2021 A fundamental step in the race to design a rapid diagnostic test for antimicrobial resistance is the separation of bacteria from their matrix. Many recent studies have been focused on the development of systems capable of separating and capturing bacteria from different liquid environments. Herein, we introduce a new approach to this issue by using the
