  • But, at the same time, CRISPR technology has been widely used in China so that the CRISPR-modified plants would provide enough food for its massive population. (inkwoodresearch.com)
  • Consequently, at the species level only a few bacteria can be identified using the technology, with an inability to distinguish intestinal flora among sub-species or strains. (biomedcentral.com)
  • The CRISPR/Cas technology has the potential to change the food and agricultural industries by making the breeding of new, improved varieties faster and more precise. (alwahahagri.com)
  • Our data show the broader diversity that exists within environmental C. difficile strains from a much less studied location and their potential role in evolution and emergence of new strains. (sruc.ac.uk)
  • Bacteriophage T4 Escapes CRISPR Attack by Minihomology Recombination and Repair. (billfryer.com)
  • It can be used with a set of predefined MacSyFinder models, "TXSScan," to identify all major secretion systems of diderm bacteria (i.e., with inner and LPS-containing outer membranes) as well as evolutionarily related cell appendages (pili and flagella). (bvsalud.org)
  • TXSScan models can be altered in the command line or customized to search for variants of known secretion systems. (bvsalud.org)
  • One of the systems constituting a natural defense mechanism is the ability to distinguish self from non‑self nucleic acids. (pjmonline.org)
  • Here, we demonstrate that HlgCB, another leucocidin, which targets the same receptors as PVL, highly contributes to S. aureus virulence in -negative strains. (cnrs.fr)
