Identification of cannabinoid-sensitive and -resistant oral bacteria

open access: yesFrontiers in Microbiology
Marijuana, an emerging risk factor for periodontitis, contains multiple potent antibacterials, particularly the phytocannabinoids. Microbial dysbiosis is a hallmark of this destructive oral disease. We examined a panel of oral bacteria for susceptibility

Transmission dynamics of Borrelia turicatae from the arthropod vector.

open access: yesPLoS Neglected Tropical Diseases, 2014
BackgroundWith the global distribution, morbidity, and mortality associated with tick and louse-borne relapsing fever spirochetes, it is important to understand the dynamics of vector colonization by the bacteria and transmission to the host.

Mapping syphilis surveillance: Insights into blood donation screening practices worldwide

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives Syphilis is caused by the bacterial spirochete Treponema pallidum and can be transmitted through blood transfusion. However, there have been less than 10 documented transfusion‐transmitted cases since World War II.

Enhanced Adhesion and OspC Protein Synthesis of the Lyme Disease Spirochete Borrelia Burgdorferi Cultivated in a Host-Derived Tissue Co-Culture System

open access: yesBalkan Medical Journal, 2013
Background: The adhesion process of Borrelia burgdorferi to susceptible host cell has not yet been completely understood regarding the function of OspA, OspB and OspC proteins and a conflict exists in the infection process. Aims: The adhesion rates of

Bacterial sialidases subvert the complement system through desialylation

open access: yesProtein Science, Volume 35, Issue 11, November 2026.
Abstract Bacterial sialidases (neuraminidases) are widely studied virulence factors, yet their impact on the complement system, a central component of innate immunity, remains poorly understood. Here, we investigate the effects of six sialidases from five human pathogens, including Bacteroides fragilis, Clostridium perfringens, Tannerella forsythia ...

Exploring the Impact of Ultrasonic Activation on the Antimicrobial Activity of Root Canal Sealers: A Year‐Long Ex Vivo Investigation Into Bacterial Survival

open access: yesInternational Endodontic Journal, Volume 59, Issue 11, Page 2424-2435, November 2026.
ABSTRACT Aim This study investigated the long‐term survival of bacteria in root canals obturated using two endodontic sealers—AH Plus Jet (AHP) and BioRoot RCS (BCS)—while also assessing the influence of ultrasonic agitation on their antimicrobial effectiveness.

Revisiting oxygen toxicity: evolution and adaptation to superoxide in a SOD-deficient bacterial pathogen

open access: yesmBio
Dioxygen (O2) is vital for aerobic life, but its utilization leads to the inevitable production of superoxide, a toxic oxidant. The prevailing theory of oxygen toxicity postulates that superoxide-scavenging enzymes (SOSEs), such as superoxide dismutases (
