Pathologists take blood from the heart to check for bacteria in the blood

Answer: yes. If a person should suffer a severe infection of the blood, via osteomyolytis or other infection, the Heart is one place bacteria may successfully hide. If a patient is quite ill or may be ill, a line (tube) will be placed in their heart via the blood vessels of their arm so that antibiotics can be pumped directly into the heart, sometimes for many weeks.
