  1. Bacterial Biofilm and its Clinical Implications.Mohammad Reza Shakibaie - 2018 - Annals of Microbiology and Research 2 (2):45-50.
    Microbial biofilm created huge burden in treatment of both community and hospital infections. A biofilm is complex communities of bacteria attached to a surface or interface enclosed in an exopolysaccharide matrix and protected from unfavorable conditions such as presence of antibiotics, host defense or oxidative stresses. Biofilms are often considered hot spot for horizontal gene transfer among same or different bacterial species. Furthermore, bacteria with increased hydrophobicity facilitate biofilm formation by reducing repulsion between the extracellular matrix and (...)

  3. Molecular Analysis and Expression of Bap Gene in Biofilm-Forming Multi-Drug-Resistant Acinetobacter Baumannii.Omid Azizi, Mohammad Reza Shakibaie & Fereshteh Shahcherghi - 2016 - Reports of Biochemistry and Molecular Biology 5 (1):1-8.
    Acinetobacter baumannii is commonly resistant to nearly all antibiotics due to presence of antibiotic resistance genes and biofilm formation. In this study we determined the presence of certain antibiotic-resistance genes associated with biofilm production and the influence of low iron concentration on expression of the biofilm-associated protein gene (bap) in development of biofilm among multi-drug-resistant A. baumannii (MDRAB). Sixty-five MDRAB isolates from clinical samples were collected. Molecular typing was carried out by random amplified polymorphism DNA polymerase (...)

    Susceptibility of Catheter-Related Klebsiella Pneumoniae Strains to Quaternary Ammonium Compounds Under Biofilm and Planktonic Conditions.Mohammad Reaza Shakibaie, Fatemeh Monirzadeh, Melika Gholamrezazadeh & Shalaleh Masoumi - 2018 - Canadian Journal Infection Control 33 (4):215-219.
    Background: The aim of this study was to evaluate the susceptibility of catheter-related Klebsiella pneumoniae isolates to two biocides (benzalkonium chloride and Deconex) under biofilm and planktonic conditions. Methods: A total of 85 strains of K. pneumoniae were isolated from catheters of inpatients hospitalized in four hospitals in Kerman, Iran. Susceptibility to antibiotics and biocides under biofilm and planktonic growths was performed using the microdilution method. Antibiofilm activity of the biocides was determined by microtiter assay. Biofilm eradication (...)

    Functional Integration and Individuality in Prokaryotic Collective Organisations.Guglielmo Militello, Leonardo Bich & Alvaro Moreno - 2020 - Acta Biotheoretica.
    Both physiological and evolutionary criteria of biological individuality are underpinned by the idea that an individual is a functionally integrated whole. However, a precise account of functional integration has not been provided so far, and current notions are not developed in the details, especially in the case of composite systems. To address this issue, this paper focuses on the organisational dimension of two representative associations of prokaryotes: biofilms and the endosymbiosis between prokaryotes. Some critical voices have been raised against the (...)

  6. Synergistic Approach of Graphene Oxide-Silver-Titanium Nanocomposite Film in Oral and Dental Studies: A New Paradigm of Infection Control in Dentistry.Siddhartha Dan, Sushil Kumar Upadhyay, Mohit Pant & Shaloo - 2021 - Biointerface Research in Applied Chemistry 11 (2):9680-9703.
    Nanoparticles have been used in numerous fields, various branches of science and engineering. These were used as a modification and to enhance the activity such as dentistry and oral investigation. The current survey uncovers that graphene oxide has been used to set up a variety of functionalized nanoparticles and progressed nanocomposites carriers. Graphene oxide shows potential in a variety of research examinations, for instance, tooth bleaching, antimicrobial activity, tooth erosion, teeth implants, toothaches, drug delivery at a specific site. All these (...)

    Non-Genetic Inheritance: Evolution Above the Organismal Level.Anton Sukhoverkhov & Nathalie Gontier - 2021 - Biosystems 1 (200):104325.
    The article proposes to further develop the ideas of the Extended Evolutionary Synthesis by including into evolutionary research an analysis of phenomena that occur above the organismal level. We demonstrate that the current Extended Synthesis is focused more on individual traits (genetically or non-genetically inherited) and less on community system traits (synergetic/organizational traits) that characterize transgenerational biological, ecological, social, and cultural systems. In this regard, we will consider various communities that are made up of interacting populations, and for which the (...)
