Genes for selenium dependent and independent formate dehydrogenase in the gut microbial communities of three lower, wood-feeding termites and a wood-feeding roach [PDF]

open access: yes, 2011
The bacterial Wood-Ljungdahl pathway for CO_2-reductive acetogenesis is important for the nutritional mutualism occurring between wood-feeding insects and their hindgut microbiota. A key step in this pathway is the reduction of CO_2 to formate,

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

A Metataxonomic Tool to Investigate the Diversity of Treponema

open access: yesFrontiers in Microbiology, 2019
The genus Treponema contains a number of human and animal pathogenic as well as symbiotic bacteria that are found in vastly different anatomical and environmental habitats. Our understanding of the species range, evolution, and biology of these important

Sex‐Specific Involvement of Gut Microbiota in Behavioral and Endocrine Responses to Chronic Predator Odor in Brandt's Voles

open access: yesIntegrative Zoology, EarlyView.
18 days of predator odor exposure altered gut microbiota, increased anxiety‐like behaviors, and elevated hypothalamic–pituitary–adrenal axis activity in Brandt's voles, with males showing behavioral habituation and females remaining sensitive. Cecal microbiota transplantation experiments confirmed that only female recipients of microbiota from predator‐

Changes in the microbiome and metabolome in captive red kangaroos (Osphranter rufus) affected by macropod progressive periodontal disease

open access: yesAustralian Veterinary Journal, EarlyView.
Macropod progressive periodontal disease (MPPD) is a severe oral condition frequently observed in captive macropods, particularly red kangaroos (Osphranter rufus), yet its underlying biological features remain poorly understood. In this exploratory descriptive study, we investigated oral and fecal microbiomes and metabolomic profiles in captive red ...

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

open access: yesClinical Oral Implants Research, EarlyView.
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 ...

Description of Treponema azotonutricium sp. nov. and Treponema primitia sp. nov., the First Spirochetes Isolated from Termite Guts [PDF]

open access: yes, 2004
Long after their original discovery, termite gut spirochetes were recently isolated in pure culture for the first time. They revealed metabolic capabilities hitherto unknown in the Spirochaetes division of the Bacteria, i.e., H2 plus CO2 acetogenesis (J.

Progress on the methods for detection of and study on Treponema pallidum

open access: yesPifu-xingbing zhenliaoxue zazhi
The traditional methods for Treponema pallidum detection are limited due to the lack of convenience and sensitivity, which affect its application in the early diagnosis of syphilis.
