Horizontal gene transfer of an IncP1 plasmid to soil bacterial community introduced by Escherichia coli through manure amendment in soil microcosms

Macedo, G.; Olesen, A.K.; Maccario, L.; Hernandez Leal, L.; Maas, P.M.F. van der (Lector); Heederik, D.; Mevius, D.; Sørensen, S.J.; Schmitt, H.

The quantification and identification of new plasmid-acquiring bacteria in representative mating conditions is critical to characterize the risk of horizontal gene transfer in the environment. This study aimed to quantify conjugation events resulting from manure application to soils and identify the …

Genome-wide analysis of bacterial determinants of plant growth promotion and induces systemic resistance by Pseudomonas fluorescens

Cheng, X.; Etalo, D.W.; Mortel, J.E. van de

Pseudomonas fluorescens strain SS101 (Pf.SS101) promotes growth of Arabidopsis thaliana, enhances greening and lateral root formation, and induces systemic resistance (ISR) against the bacterial pathogen Pseudomonas syringae pv. tomato (Pst). Here, targeted and untargeted approaches were adopted to identify …

Antimicrobial susceptibility testing of Gram-positive and -negative bacterial isolates directly from spiked blood culture media with Raman spectroscopy

H.E. Dekter (Onderzoeker); Claudia Constance Orelio (Onderzoeker); Maarten Morsink (Onderzoeker); S. Tektas (Onderzoeker); B. Vis (Onderzoeker); R. te Witt (Onderzoeker); Willem van Leeuwen (Lector)

Patients suffering from bacterial bloodstream infections have an increased risk of developing systematic inflammatory response syndrome (SIRS), which can result in rapid deterioration of the patients’ health. Diagnostic methods for bacterial identification and antimicrobial susceptibility tests are time-consuming. …

The efficiency of the NIOO-KNAW proposed decentralized sanitation system in removal of Coliforms and Escherichia coli

Kooten, W. van (Student); Truijen, G.J.P.; Sloots, P.

With increasing world population, more wastewater is produced which all need purification treatment. Removal of pathogenic organisms is important because they can cause problems to human health. This experiment will focus on the removal of human bacterial pathogens. The problem of human bacterial pathogens …

Comparative study using phenotypic, genotypic and proteomics methods for identification of coagulase-negative staphylococci

Anne J. M. Loonen (Lid Lectoraat); Arjan R. Jansz; Jeandery N. B. Bergland; Marion Valkenburg; Petra F. G. Wolffs; Adriaan J. C. van den Brule (Lector)

Five methods were compared to determine the best technique for accurate identification of coagulase-negative staphylococci (CoNS) (n=142 strains). MALDI-TOF MS showed the best results for rapid and accurate CoNS differentiation (correct identity in 99.3%). An alternative to this approach could be Vitek2 …

An evaluation of three processing methods and the effect of reduced culture times for faster direct identification of pathogens from BacT/ALERT blood cultures by MALDI-TOF MS

A.J.M. Loonen (Lid Lectoraat); A.R. Jansz; J. Stalpers; P.F.G. Wolffs; A.J.C. van den Brule (Lector)

Matrix-assisted laser desorption/ionisation time of-flight mass spectrometry (MALDI-TOF MS) is a fast and reliable method for the identification of bacteria from agar media. Direct identification from positive blood cultures should decrease the time to obtaining the result. In this study, three different …

Acceleration of direct identification of S.aureus versus Coagulase Negative Staphylococci from blood culture material: a comparison of six bacterial DNA extraction methods

A.J.M. Loonen (Lid Lectoraat); A.R. Jansz; H. Kreeftenberg; C. A. Bruggeman; P.F.G. Wolffs; A. J. C. van den Brule (Lector)

To accelerate differentiation between Staphylococcus aureus and Coagulase Negative Staphylococci (CNS), this study aimed to compare six different DNA extraction methods from 2 commonly used blood culture materials, i.e. BACTEC and Bact/ALERT. Furthermore, we analyzed the effect of reduced blood culture …
