A Co-Association of Streptococcus mutans and Veillonella parvula/dispar in Root Caries Patients and Biofilms.

Root caries in geriatric patients is a growing problem as more people are maintaining their natural teeth into advanced age. We determined the levels of various bacterial species previously implicated in root caries disease or health using quantitative real-time PCR in a pilot study of 7 patients with 1 to 4 root caries lesions per person. Levels of 12 different species on diseased roots compared to healthy (contralateral control) roots were measured.

Supernumerary tooth autotransplantation to replace missing maxillary central incisor using three-dimensional replica: A 6-year follow-up.

Introduction: Tooth autotransplantation is a viable surgical treatment option for patients with missing permanent teeth. Premolars are generally used for autotransplantation but often require extensive modifications. This case report evaluates the use of supernumerary tooth as an alternative option for premolar autotransplantation.

The oxidative fumarase FumC is a key contributor for E. coli fitness under iron-limitation and during UTI.

The energy required for a bacterium to grow and colonize the host is generated by metabolic and respiratory functions of the cell. Proton motive force, produced by these processes, drives cellular mechanisms including redox balance, membrane potential, motility, acid resistance, and the import and export of substrates. Previously, disruption of succinate dehydrogenase (sdhB) and fumarate reductase (frdA) within the oxidative and reductive tricarboxylic acid (TCA) pathways in uropathogenic E.

Acinetobacter baumannii neonatal mastitis: a case report.

Introduction: Neonatal mastitis is a rare infection. When it does occur, infants younger than 2 months of age are typically affected and the majority of cases are caused by Staphylococcus aureus. We present the first reported case of neonatal mastitis caused by Acinetobacter baumannii, an unusual organism for this type of infection.

Exposure to traffic pollution, acute inflammation and autonomic response in a panel of car commuters.

Background: Exposure to traffic pollution has been linked to numerous adverse health endpoints. Despite this, limited data examining traffic exposures during realistic commutes and acute response exists.

Objectives: We conducted the Atlanta Commuters Exposures (ACE-1) Study, an extensive panel-based exposure and health study, to measure chemically-resolved in-vehicle exposures and corresponding changes in acute oxidative stress, lipid peroxidation, pulmonary and systemic inflammation and autonomic response.
