Antimicrobial activity of two South African honeys produced from indigenous and species on selected micro-organisms [PDF]

, 2008
Background Honey has been shown to have wound healing properties which can be ascribed to its antimicrobial activity. The antimicrobial activity can be effective against a broad spectrum of bacterial species especially those of medical importance. It has

Infectious seeds of valve calcification: Exploring the bacterial hypothesis in the pathogenesis of calcific aortic valve disease

European Journal of Clinical Investigation, Volume 56, Issue 3, March 2026.
Abstract Background Calcific aortic valve disease (CAVD) is a multifactorial condition characterized by progressive leaflet calcification with a potential role for bacterial colonization in its pathogenesis. This study investigates clinical, microbiological and molecular features of calcified versus non‐calcified aortic regurgitation (AR) valves ...

Metabolic changes associated with adaptive resistance to daptomycin in Streptococcus mitis-oralis

BMC Microbiology, 2020
Background Viridans group streptococci of the Streptococcus mitis-oralis subgroup are important endovascular pathogens. They can rapidly develop high-level and durable non-susceptibility to daptomycin both in vitro and in vivo upon exposure to daptomycin.

Impact of Erythritol Air‐Polishing on Titanium Implant Surface Properties and Bacterial Colonization: An In Vitro Study

Clinical and Experimental Dental Research, Volume 12, Issue 1, February 2026.
ABSTRACT Objectives This study aimed to investigate the effect of erythritol air‐polishing on implant surface topography and bacterial colonization, and to determine the antimicrobial activity of erythritol powder. Materials and Methods Titanium implants, with machined/acid‐etched hybrid design, were divided into three groups: erythritol air‐polishing ...

Computational Validation of Multi‐Epitope mRNA Vaccine Targeting Streptococcus anginosus Surface Protein (TMPC) as an Effective Alternative Treatment to Reduce Gastric Cancer

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Design process for messenger RNA vaccines. Candidate proteins are initially screened using immunoinformatics, after which selected epitopes are assembled into a multi‐epitope vaccine. The vaccine construct was evaluated through molecular docking, molecular dynamics simulations, and in silico immune simulations, followed by population coverage analysis ...

Tumor Immunotherapy and Microbiome: From Bench‐to‐Bedside Applications

MedComm, Volume 7, Issue 2, February 2026.
The microbiome is related to the efficacy of immunotherapy and can be utilized to predict the efficacy and adverse reactions of immunotherapy. Microbiome‐targeted intervention strategies can improve the efficacy of ICI, but necessitating more comprehensive exploration.

Infection of Streptococcus oralis NCTC 11427 by pneumococcal phages

FEMS Microbiology Letters, 1989
We have found a group of pneumococcal bacteriophages (Cp-1, Cp-7) that can successfully infect and replicate in Streptococcus oralis, whereas Dp-1 was unable to infect this species. We have also developed conditions that allowed transfection of S. oralis using Dp-1 DNA.

Antimicrobial‐Releasing Implant Substrates for Combating Oral Biofilms: An In Vitro Study

Clinical Oral Implants Research, Volume 37, Issue 2, Page 210-223, February 2026.
ABSTRACT Background and Objectives Peri‐implantitis, a biofilm‐associated inflammatory disease, significantly threatens dental implant longevity. Current treatments face limitations due to biofilm robustness. This study evaluates the efficacy of antimicrobial‐releasing titanium‐silica (Ti/SiO2) composite implant systems against multispecies oral ...
