Diverse soil-resident bacteria can contribute to plant growth and health, but the molecular mechanisms enabling them to effectively colonize their plant hosts remain poorly understood. We used randomly barcoded transposon mutagenesis sequencing (RB-TnSeq) in Pseudomonas simiae, a model root-colonizing bacterium, to establish a genome-wide map of bacterial genes required for colonization of the ...
Listeria monocytogenes is a facultative intracellular bacterial pathogen that is frequently associated with food-borne infection. Of particular concern is the ability of L. monocytogenes to breach the blood-brain barrier, leading to life-threatening meningitis and encephalitis. The mechanisms used by bacterial pathogens to infect the brain are not fully understood. Here we show that L. monocyto...
Bacillus amyloliquefaciens QST713 and B. firmus I-1582 are bacterial strains which are used as active ingredients of commercially-available soil application and seed treatment products Serenade® and VOTiVO®, respectively. These bacteria colonize plant roots promoting plant growth and offering protection against pathogens/pests. The objective of this study was to develop a qPCR protocol to quant...
Background With monthly reports of decreased bacterial susceptibility to antibiotics and the soaring incidence of invasive infections, it becomes increasingly important to assess bacterial colonization, as this can easily constitute a reservoir for infection. Entering the community for kindergarten and school training is an important step for children, particularly since this may be associated ...
One of the simplest hypotheses used to explain species coexistence is the competition-colonization trade-off, that is, species can stably coexist in a landscape if they show a trade-off between competitive and colonization abilities. Despite extensive theory, the dynamics predicted to result from competition-colonization trade-offs are largely untested. Landscape change, such as habitat destruc...
Background: Although implants have shown to have a high success rate, clinicians are also called upon to encounter numerous complications and failures. Among the numerous reasons of failures, peri-implantitis is reported to account for 10% of the failures. As the oral cavity provides a natural habitat for various micro-organism due to its non-shedding surface, there is some evidence that gram-n...
