The pneumonia causing bacteria Streptococcus pneumonae is able to migrate to the heart. There it can cause cell death in the heart tissue. A study published on September 18th in PLOS Pathogens demonstrates that S. Pneumonae can migrate from the lungs to the heart in mice and rhesus macaques. Continue reading

The hormones excreted during stress causes bacteria to release enzymes that break down their own biofilm. Potentially, these enzymes also cause plaque deposits to rupture in the bloodstream, leading to a heart attack. The results were published this week in mBio, the online open-access journal of the American Society for Microbiology. Continue reading
