Peptides as quorum sensing molecules : measurement techniques and obtained levels in vitro and in vivo [PDF]

open access: yes, 2017
The expression of certain bacterial genes is regulated in a cell-density dependent way, a phenomenon called quorum sensing. Both Gram-negative and Gram-positive bacteria use this type of communication, though the signal molecules (auto-inducers) used by ...

Resistance mechanisms of Gram-positive bacteria

open access: yesInternational Journal of Medical Microbiology, 2002
The introduction and increasing use of antibiotics for antibacterial therapy has initiated a rapid development and expansion of antibiotic resistance in microorganisms, particularly in human pathogens. Additionally, a shift to an increase in number and severity of Gram-positive infections has been observed the last decades. Common to these pathogens is
