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.
