Evaluation of bacterial internalization using qRT-PCR.
1Bacterial resistance to antibiotics currently represents a topic of high interest. Unfortunately, studies addressing their adaptation and multidrug tolerance latency are not sufficient for a comprehensive description of the pathogen-host molecular interaction mechanisms (interactome) and the bacterial internalization into human cells, which leads to modified human genes. Bacterial persisters a...
متن کاملEffect of Subinhibitory concentrations of imipenem and piperacillin on transcriptional expression of algD and lasB genes in Pseudomonas aeruginosa
Sub Minimal Inhibitory concentrations (sub-MIC) of antibiotics, although not able to kill bacteria, can be effect on their physico- chemical characteristics and functions. This study aimed to investigate the effect of sub-MIC of imipenem and piperacillin on the transcriptional expression of virulence related genes algD and lasB in Pseudomonas auroginosa. Five clinical isolates of P. aeruginosa ...
متن کاملNo Control Genes Required: Bayesian Analysis of qRT-PCR Data
BACKGROUND Model-based analysis of data from quantitative reverse-transcription PCR (qRT-PCR) is potentially more powerful and versatile than traditional methods. Yet existing model-based approaches cannot properly deal with the higher sampling variances associated with low-abundant targets, nor do they provide a natural way to incorporate assumptions about the stability of control genes direct...
متن کاملGenetic Diversity of phlD from 2,4-Diacetylphloroglucinol-Producing Fluorescent Pseudomonas spp.
ABSTRACT Fluorescent Pseudomonas spp. that produce 2,4-diacetylphloroglucinol (2,4-DAPG) have biocontrol activity against damping-off, root rot, and wilt diseases caused by soilborne fungal pathogens, and play a key role in the natural suppression of Gaeumannomyces graminis var. tritici, known as take-all decline. Diversity within phlD, an essential gene in the biosynthesis of 2,4-DAPG, was stu...
متن کاملIdentification of differences in genome content among phlD-positive Pseudomonas fluorescens strains by using PCR-based subtractive hybridization.
Certain 2,4-diacetylphloroglucinol-producing strains of Pseudomonas fluorescens colonize roots and suppress soilborne diseases more effectively than others from which they are otherwise phenotypically almost indistinguishable. We recovered DNA fragments present in the superior colonizer P. fluorescens Q8r1-96 but not in the less rhizosphere-competent strain Q2-87. Of the open reading frames in ...
