In vitro effects of antimicrobial agents on planktonic and biofilm forms of staphylococcus saprophyticusisolated from patients with urinary tract infections
(2019-01-01)
Bacterial biofilms play an important role in urinary tract infections (UTIs), being responsible for persistent infections that lead to recurrences and relapses. Staphylococcus saprophyticus is one of the main etiological ...
Effect of DLC films with and without silver nanoparticles deposited on titanium alloy
(2019-11-01)
Diamond-like carbon (DLC) film is a biocompatible hard coating material that can prevent the leaching of metal ions. This study evaluates the structural characteristics of DLC, with and without silver nanoparticles, deposited ...
Antibiofilm effects of Thymus vulgaris and Hyptis spicigera essential oils on cariogenic bacteria
(2021-03-01)
Aim: The inhibitory and antibiofilm effects of Thymus vulgaris (EOTv) and Hyptis spicigera essential oils (EOHs) on cariogenic microorganisms were evaluated. Materials & methods: The chemical characterization of EOTv was ...
Antimicrobial effects of photodynamic therapy with Fotoenticine on Streptococcus mutans isolated from dental caries
(2021-06-01)
Photodynamic therapy (PDT) is a promising strategy to control cariogenic pathogens, such as Streptococcus mutans. Seeking to reach the total bacterial elimination from dental surfaces, novel photosensitizers have been ...
Structural and quantitative analysis of a mature anaerobic biofilm on different implant abutment surfaces
(2016-04-01)
Statement of problem The longevity of dental implants depends on the absence of inflammation in the periimplant tissue. Similar to teeth, pathogenic bacteria can adhere on implant abutment surfaces and cause periimplant ...
The multifaceted roles of metabolic enzymes in the Paracoccidioides species complex
(Frontiers Research Foundation, 2014-12-19)
Paracoccidioides species are dimorphic fungi and are the etiologic agents of paracoccidioidomycosis, which is a serious disease that involves multiple organs. The many tissues colonized by this fungus suggest a variety of ...
Natural killer cell signal transduction mechanism mediated by lipopolysaccharide activation
(1998)
The increase in human natural killer cell activity (NKCA) in samples of peripheral blood mononuclear cells (PBMC) elicited by their incubation with bacterial lipopolysaccharide (LPS), appears to result from an indirect ...
