COVID alters respiratory microbiota
Apr. 25, 2023—COVID-19 infection alters the microbes of the upper respiratory tract for at least several weeks, and such disturbances could impact disease severity and be targets for therapeutic interventions.
Gut microbiota and lung fibrosis
Feb. 6, 2023—Microorganisms residing in the gut influence the severity of lung fibrosis in mouse models, suggesting that modifying the gut microbiota may offer therapeutic benefit for patients.
Is drinking tea good for your gut?
Jan. 19, 2023—Microbiome profiling of older Chinese adults showed that tea drinking changed the diversity and abundance of some bacteria in men but not women — effects that may contribute to a reduced risk of hypertension.
Microbiome reflects COVID-19 severity
Mar. 14, 2022—Characterization of the upper respiratory tract microbiome could help predict outcomes for COVID-19 infection, Vanderbilt researchers have discovered.
Invasive strep can defy zinc toxicity
Feb. 28, 2022—Vanderbilt researchers find that invasive Group B Streptococcus strains, a significant risk to pregnant patients and infants, can grow in presence of toxic zinc levels.
Team to study using probiotics to reduce heart disease risk
Feb. 3, 2022—A Vanderbilt research team has received a $7 million grant from the National Institutes of Health (NIH) to understand how alcohol’s effect on the gut microbiome drives heart disease.
Salmonella overcomes host resistance
Jan. 13, 2022—The invading pathogen Salmonella, a common cause of food poisoning, can change its metabolism to overcome host resistance to its colonization.
Oral microbes and gastric cancer
Dec. 13, 2021—Studies in three large population cohorts that include Asian, African American and European American people support a role for the oral microbiota — the collection of microbial species in the mouth — in gastric cancer development.
Who’s who in the respiratory landscape
Nov. 15, 2021—A metatranscriptomics method developed by Vanderbilt researchers simultaneously characterizes viruses, microbiome and host response in nasal swabs, opening opportunities to explore molecular interactions directly in clinical samples.
Study reveals missing link between high-fat diet, microbiota and heart disease
Aug. 12, 2021—A high-fat diet disrupts the biology of the gut’s inner lining and its microbial communities — and promotes the production of a metabolite that may contribute to heart disease, according to a study published Aug. 13 in the journal Science.
‘Friendly’ bacteria may impact COVID severity
Mar. 11, 2021—The U.S. Centers for Disease Control and Prevention (CDC) has awarded Vanderbilt University Medical Center a two-year, $3.7-million contract to determine genetic and bacterial factors that may increase the risk for severe illness and death from COVID-19.
Probiotic protection
Mar. 4, 2021—A probiotic factor given early in life to mice prevented intestinal inflammation in adulthood, providing a rationale for probiotic intervention in individuals at high risk of developing inflammatory bowel disease.
