Description
Arezoo Dehghan and colleagues search heart valve tissue for hard-to-grow microbes in patients with valve infection in Tehran in 2026 work. Standard blood tests miss some causes of infective endocarditis, a life-threatening heart infection. The team tested samples from 232 patients who had valve replacement surgery between 2021 and 2025.
DNA tests found Brucella species most often, followed by the Q fever microbe, Bartonella, and the Whipple disease microbe. Breathlessness linked to several of these infections, while fever and sweating linked to Brucella. The authors argue that tissue DNA testing should play a larger role when blood cultures stay negative.
