Review ArticleOpen accessEvery word in the titleMultidrug Resistant Microorganisms (MDR) and Biofilm Producers: A Challenge for Hospital Infectious ControlDaniel Lucio, Elizabeth Proaño, Alberto Bustillos et al.Antimicrobial Resistance (AMR) now represents a major threat to contemporary health care, especially in hospitals, where repeated antimicrobial exposure selects for and facilitates the dissemination of Multidrug-Resistant (MDR) microorganisms. Biofilm growth adds another layer of persistence by increasing microbial tolerance, supporting long-term colonization of medical devices, and worsening clinical and economic outcomes. This narrative review synthesizes evidence on MDR biofilm-forming … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 12 Sep 2026 · 774 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Role of Living, Resident Bacterial Biofilm Populations in the Osseointegration of Oral ImplantsStephen Nelson, Honghua Hu et al.This study presents a human jawbone model which explains bone health, disease and quality and the osseointegration interphase, at the cell level. Curation of 454 pyrosequencing data obtained from 153 bone, serous-effusion and granulation samples taken from 40 patients during two-stage dental implant installation, revealed a 20 phyla jawbone microbiome with total genera of 387. Multivariate statistical ordination of curated … …Current Research in Dentistry, Vol. 14, Issue 1 · 16 Nov 2023 · 8,245 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDifferential Gene Expression of Peroxide Resistant Protein (AhpC) in Planktonic and Biofilm State of Uropathogenic Escherichia coli CellsOmar Sadik Shalal, Ani-Simona SevastreThe gastrointestinal tract seems to be the primary reservoir of Uropathogenic Escherichia coli (UPEC) in humans. UPEC strains harbor the Urinary Tract (UT) and cause Urinary Tract Infections (UTI) which might represent a serious threat to human life. To counteract with the damage caused by the Reactive Oxygen Species (ROS), bacterial strains produce various enzymes and proteins like Alkyl hydroperoxide … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 13 Oct 2023 · 5,324 accessesView PDFCite
Case ReportOpen accessEvery word in the titleBacterial Biofilm Persistence in Human Jawbone Following Tooth Extraction: Implications of Surgical Debridement and Resident Population-Shift for Oral ImplantsStephen Nelson, Honghua Hu et al.Intra-radicular infection theory assumes that when an infected tooth is extracted, the main source of infection is removed and any residual contaminating bacteria are killed by the immune response, then normal healing ensues. This study investigated whether bacteria and bacterial biofilms persisted in deep bone space following tooth extraction. The study was conducted on two adult male patients seeking dental … …Current Research in Dentistry, Vol. 14, Issue 1 · 31 May 2023 · 6,861 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleEffect of Certain Disinfectants and Antibiotics on the Biofilm Formed by Staphylococcus Aureus Isolated from Medical Devices at the University Hospital Center of Sidi Bel Abbes (Algeria)Ibtissem Kara Terki, Hafida Hassaine, Assia Kara Terki et al.Staphylococcus aureus is one of the species that are most frequently isolated from medical devices. The ability to produce a biofilm is an important step in the pathogenesis of these staphylococci; biofilm formation is strongly dependent on the environmental conditions and also on the antibiotics and disinfectants used in the treatment of infections. In this study, 28 staphylococcus aureus isolated … …American Journal of Infectious Diseases, Vol. 15, Issue 3 · 12 Sep 2019 · 7,171 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleThe Role of the Microbial Biofilm in the Pathogenesis of Periodontal Disease: An UpdateAndreas L. Ioannou, Konstantinos Siormpas, Miltiades E. Mitsias, Georgios A. KotsakisMicrobial biofilm is generally considered to be an etiologic factor for the diseases of the periodontium and has been and continues to be the main focus of avid periodontal researchers. Based on our current understanding of the role of the biofilm in the pathogenesis of periodontal disease, each different species seems to have a specific role to fulfill in this … …Current Research in Dentistry, Vol. 5, Issue 1 · 6 May 2015 · 6,906 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCorrelation Between in vitro Biofilm Formation and Virulence Properties of Extra-Intestinal Pathogenic Escherichia Coli (Expec)Md. Fakruddin, Khanjada Shahnewaj Bin Mannan, Reaz Mohammad MazumdarAbout 65 Escherichia coli strains isolated from extra-intestinal sites were included in this study to determine their biofilm formation capability and virulence properties. About 87% ExPEC isolates were motile and 12.3% were found to be non-motile. Only 12.30% isolates were strong biofilm former (SBF >1.5) whereas 18.46% isolates were non biofilm former. About 71% isolates were capable to express curli … …OnLine Journal of Biological Sciences, Vol. 14, Issue 4 · 14 Jan 2015 · 6,942 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntibiotic Resistance in Co-Culture Biofilm of Listeria monocytogenes J0161Prem Saran Tirumalai, Soam PrakashProblem statement: Do naturally group-living bacteria express genes the same way as they do in lab grown pure cultures? An intriguing question. Listeria monocytogenes, a dreaded pathogen has been and continues to be a subject of study with reference to gene expressions. However, all studies concerning the gene expression of L. monocytogenes have been done on pure culture states. Our … …Current Research in Microbiology, Vol. 3, Issue 1 · 29 Mar 2012 · 10,216 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication of Moving Bed Biofilm Process for Biological Organics and Nutrients Removal from Municipal WastewaterM. Kermani, B. Bina, H. Movahedian et al.In this study, experiments have been conducted to evaluate the organics and nutrients removal from synthetic wastewater by a laboratory scale moving bed biofilm process. For nutrients removal, moving bed biofilm process has been applied in series with anaerobic, anoxic and aerobic units in four separate reactors. Moving bed biofilm reactors were operated continuously at different loading rates of nitrogen … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 9,092 accessesView PDFCite
