VUMC team discovers how bacterial pathogen survives without water
May. 5, 2022—Vanderbilt researchers are studying a bacterial pathogen that can survive on hospital surfaces — without water — for months, an ability that has helped it become a leading cause of hospital-acquired infections.
Study identifies antibodies that block alphaviruses
Aug. 20, 2020—Researchers at Vanderbilt University Medical Center have identified antibodies that, in animals, block infection by alphaviruses, which can cause chronic and debilitating joint pain and arthritis and are an increasing global health concern.
C. diff captures blood cell cofactor to build defensive shield
Jun. 10, 2020—Vanderbilt University Medical Center scientists have identified a C. diff protein system that senses and captures heme (part of hemoglobin) to build a protective shield that fends off threats from our immune system and antibiotics.
Antibody finding raises hopes for Marburg, COVID-19 treatments
Apr. 30, 2020—Monoclonal antibodies against Marburg virus — a more lethal cousin of the RNA virus that causes COVID-19 — may aid in the development of antibody “cocktails” to counter viral infection.
VUMC-led team isolates antibody that blocks bird flu
Dec. 12, 2019—VUMC scientists are redoubling their efforts to help people fight off bird flu. Their focus is H7N9, one of the most dangerous of the influenza viruses that have been transmitted from birds to humans.
A “public” target for HIV
Jun. 8, 2018—Common sequences of antibodies against HIV may be key to developing a successful vaccine strategy for the virus.
Excess dietary manganese increases risk of staph infection in heart
Sep. 21, 2017—Too much dietary manganese — an essential trace mineral found in leafy green vegetables, fruits and nuts — promotes infection of the heart by the bacterium Staphylococcus aureus (“staph”).
VUMC investigators find pathogens work together to infect host
Nov. 3, 2016—Pseudomonas aeruginosa and Staphylococcus aureus — two pathogens that frequently co-infect the lungs of patients with cystic fibrosis — appear to cooperate with each other, Vanderbilt investigators have discovered. When pseudomonas is starved for metal by the host, it shuts down the production of factors that would normally kill staph, promoting a co-infection.
Vanderbilt researchers develop potential treatment to fight mosquito-borne chikungunya virus
Jul. 8, 2015—In late 2013 the Caribbean had its first case of the mosquito-borne chikungunya virus. Today there have been almost 1.2 million cases in 44 countries or territories, including 177 cases in 31 U.S. States.
Staph ‘gangs’ share nutrients during infection: study
Oct. 16, 2014—Antibiotic-resistant bacteria can share resources to cause chronic infections, Vanderbilt investigators have discovered. The findings shed light on a long-standing question in infectious diseases and may inform new treatment strategies.
Neural receptor for reovirus
Jul. 18, 2014—A newly identified receptor allows mammalian reovirus to infect neurons, shedding light on factors important for viral encephalitis.
