Bones osteomyelitis Osteomyelitis Osteomyelitis is a bone infection usually caused by bacteria, mycobacteria, or fungi. Bacteria, mycobacteria, or fungi can infect bones by spreading through the bloodstream or, more often, by Joints infectious arthritis Infectious Arthritis Infectious arthritis is infection in the fluid and tissues of a joint usually caused by bacteria but occasionally by viruses or fungi.
Bacteria, viruses, or fungi may spread through the bloodstream In bacteremia, bacteria tend to lodge and collect on certain body structures, such as abnormal heart valves. Bacteria are particularly likely to collect on any artificial material present in the body, such as intravenous catheters and artificial prosthetic joints and heart valves. These collections colonies of bacteria may remain attached to the sites and continuously or periodically release bacteria into the bloodstream. Ordinary activities sometimes cause bacteremia in healthy people.
For example, vigorous toothbrushing can cause bacteremia because bacteria living on the gums around the teeth are forced into the bloodstream. Bacteria may also enter the bloodstream from the intestine during digestion. Bacteremia that occurs during ordinary activities rarely leads to infections. Dental or medical procedures can lead to bacteremia. During dental procedures as during tooth cleaning by a dental hygienist , bacteria living on the gums may become dislodged and enter the bloodstream.
Bacteremia may also occur when catheters are inserted into the bladder or tubes are inserted into the digestive tract or urinary tract. Bacteria may be present in the area where the catheter or tube has been inserted such as the bladder or intestine.
So even though sterile techniques are used, these procedures may move bacteria into the bloodstream. Surgical treatment of infected wounds, abscesses collections of pus , and pressure sores can dislodge bacteria from the infected site, causing bacteremia.
