A New Class of Quorum Quenching Molecules from Staphylococcus Species Affects Communication and Growth of Gram-Negative Bacteria
A New Class of Quorum Quenching Molecules from Staphylococcus Species Affects Communication and Growth of Gram-Negative Bacteria Ya-Yun Chu1, Mulugeta Nega1, Martina Wo¨ lfle2, Laure Plener3, Stephanie Grond2, Kirsten Jung3, Friedrich Go¨ tz1* 1 Interfaculty Institute of Microbiology and Infectious Diseases Tu¨bingen (IMIT), Microbial Genetics, University of Tu¨bingen, Tu¨bingen, Germany, 2 Organic Chemistry, University of Tu¨bingen, Tu¨bingen, Germany, 3 Munich Center for Integrated Protein Science (CiPSM) at the Department of Microbiology, Ludwig-Maximilians-Universita¨t Mu¨nchen, Martinsried, Germany Abstract The knowledge that many pathogens rely on cell-to-cell communication mechanisms known as quorum sensing, opens a new disease control strategy: quorum quenching. Here we report on one of the rare examples where Gram-positive bacteria, the ‘Staphylococcus intermedius group’ of zoonotic pathogens, excrete two compounds in millimolar concentrations that suppress the quorum sensing signaling and inhibit the growth of a broad spectrum of Gram-negative beta- and gamma-proteobacteria. These compounds were isolated from Staphylococcus delphini. They represent a new class of quorum quenchers with the chemical formula N-[2-(1H-indol-3-yl)ethyl]-urea and N-(2-phenethyl)-urea, which we named yayurea A and B, respectively. In vitro studies with the N-acyl homoserine lactone (AHL) responding receptor LuxN of V. harveyi indicated that both compounds caused opposite effects on phosphorylation to those caused by AHL. This explains the quorum quenching activity. Staphylococcal strains producing yayurea A and B clearly benefit from an increased competitiveness in a mixed community.

Podsumowanie Coagulase-positive species of the genus Staphylococcus – taxonomy, pathogenicity Abstract: Staphylococci constitute an important component of the human microbiome. Most of them are coagulase-negative species, whose importance in the pathogenesis of human infections has been widely recognized and is being documented on a regular basis. Until recently, the only well-known coagulase-positive staphylococcus species recognized as human pathogen was Staphylococcus aureus. Previously, the ability to produce coagulase was used as its basic diagnostic feature, because other coagulase-positive species were associated with animal hosts. Progress in the laboratory medicine, in which automatic or semi-automatic systems identify the staphylococci species, revealed a phenomenon of spreading of the coagulase positive staphylococci to new niches and hosts, as they are being isolated from human clinical materials with increasing frequency. As a result, many reaserchers and laboratories have turned their attention to the phenomenon, which caused an inflow of new data on these species. An increasingly expansive pathogenic potential of coagulase-positive staphylococci against humans has been documented. In the presented study, recent data on both S. -
