Excess dietary manganese increases risk of staph infection in heart

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”).

Investigators use light to kill microbial ‘vampires’

On July 24 Vanderbilt scientist Eric Skaar, Ph.D., MPH, summarized his group’s latest paper in a tweet: “If S. aureus is going to drink our blood like a vampire, let’s kill it with sunlight.”

VUMC investigators find pathogens work together to infect host

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.

Study shows excess dietary zinc worsens C. diff infection

Too much dietary zinc increases susceptibility to infection by Clostridium difficile — “C. diff” — the most common cause of hospital-acquired infections.

Physician-scientist is dream job for Vanderbilt’s Cassat

Jim Cassat, M.D., Ph.D., a pediatric infectious disease specialist who joined the Vanderbilt faculty this summer, loves taking care of children with bone infections and doing research to understand the host-pathogen interactions during these invasive infections.

Staph ‘gangs’ share nutrients during infection: study

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.
