Today, childhood caries is main health related disease it affects many schooling children in countries especially developed by lactic acid bacteria. So this present the isolating 50 bacteria from different decay affected children’s Fen Dental Clinic, Tirupur Dt. The emerging LAB confirmed phenotype and genotype characterization. After, pathogen screened for production of biofilm to check resist...

Corrosion inhibition of SAE 1018 steel by Pseudomonas fragi and Escherichia coli biofilms has been evaluated using batch cultures in rich medium (LB) and seawater-mimicking medium (VNSS) at 23 degrees C and 30 degrees C with or without daily medium replenishment. Biofilm components have been stained simultaneously for polysaccharide (calcofluor) and live and dead cells (Live/Dead Baclit viabili...

Escherichia coli strain 15 (ATCC 9723), which forms robust biofilms, was grown under optimal biofilm conditions in NaCl-free Luria-Bertani broth (LB*) or in LB* supplemented with one of the non-metabolizable analogues 2-deoxy-d-glucose (2DG), methyl α-d-mannopyranoside (αMM), or methyl α-d-glucopyranoside (αMG). Biofilm growth was inhibited by mannose analogue 2DG even at very low concentration...

Aggregatibacter actinomycetemcomitans, a Gram-negative bacterium, and Candida albicans, a polymorphic fungus, are both commensals of the oral cavity but both are opportunistic pathogens that can cause oral diseases. A. actinomycetemcomitans produces a quorum-sensing molecule called autoinducer-2 (AI-2), synthesized by LuxS, that plays an important role in expression of virulence factors, in int...

BACKGROUND Staphylococcus aureus and Pseudomonas aeruginosa are major pathogens in chronic rhinosinusitis (CRS) and their biofilms have been associated with poorer postsurgical outcomes. This study investigated the distribution and anti-biofilm effect of cationic (+) and anionic (-) phospholipid liposomes with different sizes (unilamellar and multilamellar vesicle, ULV and MLV respectively) on ...

Microbial biofilms, which are formed when bacterial and/or yeast cells adhere to abiotic and biotic surfaces represent the most prevalent type of virulent factor involved in the crucialdevelopment of clinical infection exhibiting resistance to antimicrobial agents. Metalnanotechnology chemistry has the potential to prevent the formation of these life-threatening biofilms on life supporting devi...

Abstract Urinary tract infections are second most important diseases worldwide due to the increased amount of antibiotic resistant microbes. Among Gram negative bacteria, P. mirabilis is dominant biofilm producer in urinary next E. coli. Biofilm a process that produced self-matrix more virulence pathogens on colloidal surfaces. Based above fact, this study was concentrated inhibit formation by ...

Background: The study aims to evaluate the antibacterial activity of Trigona honey against S. pneumonia. Methods: effect on pneumonia investigated using agar well diffusion, MIC, MBC, biofilm formation and RT-qPCR.
 Results: samples showed larger zones inhibition pneumonia, 22.2±0.4 at 100% concentration. possessed lowest MIC50 MIC90 pneumoniae, 25%, 30%, 12.5% 25% (w/v) respectively. perm...

In the form of biofilms, bacteria exhibit more resistance to antibiotics. Biofilm formers can withstand severe conditions and the host's defense system. Therefore, it is necessary to search for effective biofilm inhibitors. In this study, we investigated the effect of a chloroform extract of turmeric on biofilm formation against antibiotic resistant bacteria. The extract exhibited its antibiofi...

Biofilm formation by pathogenic bacteria is a hallmark of chronic infections. In many cases, lectins play key roles in establishing biofilms. The pathogen Pseudomonas aeruginosa often exhibiting various drug resistances employs its lectins LecA and LecB as virulence factors and biofilm building blocks. Therefore, inhibition of the function of these proteins is thought to have potential in devel...
