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.

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 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.

Common sequences of antibodies against HIV may be key to developing a successful vaccine strategy for the virus.

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”).

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.

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.
