Use of quantitative PCR and culture methods to characterize ecological flux in bacterial biofilms.

چکیده
An in vitro model of supragingival plaque associated with gingivitis was characterized by traditional culture techniques, comparative 16S rRNA gene sequencing of isolates, and quantitative PCR (QPCR). Actinomyces naeslundii, Prevotella spp., and Porphyromonas gingivalis increased under conditions emulating gingivitis. Gram-negative species and total bacteria were dramatically underestimated by culture compared to the estimates obtained by QPCR.

Investigation of the Relationship between Antibiotic Resistance and Biofilm Production in Klebsiella pneumoniae Isolated from Hamadan Hospitals, Iran
Background and Objective: The role of biofilm formation by bacteria has been considered as an important stage in the pathogenesis of Klebsiella pneumoniae. This pathogen is one of the most important opportunistic pathogen agents of nosocomial infections, such as pneumonia, urinary tract infections, invasive infections, and surgical site infections. This study aimed to investigate the biofilm pr...
متن کاملOne-step purification and characterization of alginate lyase from a clinical Pseudomonas aeruginosa with destructive activity on bacterial biofilm
Objective(s): Pseudomonas aeruginosais a Gram-negative and aerobic rod bacterium that displays mucoid and non-mucoid phenotype. Mucoid strains secrete alginate, which is the main agent of biofilms in chronic P. aeruginosa infections, show high resistance to antibiotics; consequently, the biological disruption of mucoid P. aeruginosa biofilms is an attractive area of study for researchers. Algin...
متن کاملComparison of PCR and Culture Methods for Diagnosis of Enteropathogenic Campylobacter in Fowl Feces
Enteritis due to Campylobacter is the most common cause of acute bacterial diarrhea worldwide. In most cases, infection occurs as a result of consuming contaminated water or food, especially raw meat of fowls. Campylobacters are saccharolytic and fastidious bacteria. These traits limit the number of available biochemical tests by which isolates may be differentiated. These limitations might, in...
متن کاملEffects of biofilm formation in bacteria from different perspectives
Bacterial communities are able to form complex and three-dimensional biofilm structures. Biofilm formation is an ancient and integral component of the prokaryotic life cycle and a key factor for survival in diverse niches. In biofilms, bacterial lifestyle changes from free-floating cells to sessile cells. Presence in biofilms gives new traits to bacteria, which distinguish them from free cells....
متن کاملThe effect of bromhexine, gentamicin and imipenem on biofilm of standard bacterial Escherichia coli and Pseudomonas aeruginosa by ELISA method
Background: Biofilms are a collection of microorganisms that have the ability to stick to different levels. Due to the difficulty of treatment of bacterial biofilm infections and their lack of recognition by conventional diagnostic methods, this study aimed to provide a new method of identification and the effect of related drugs on Pseudomonas aeruginosa and Escherichia coli biofilms. Material...
