Streptococcus mutans, SEM Featured 8 Jan 2019 Print

Streptococcus mutans, SEM

Streptococcus mutans. Coloured scanning electron micrograph (SEM). S. mutans is a coccoid shaped, Gram-positive, anaerobic bacteria that is part of the normal bacteria flora of the mouth. It metabolizes sucrose to lactic acid and is a leading cause of tooth enamel decay. The acidic environment created in the mouth by this process is what causes the highly mineralized tooth enamel to decay. S. mutans is one of a few specialized organisms equipped with receptors for adhesion to the surface of teeth. Sucrose is utilized by S. mutans to produce a sticky, extracellular, dextran-based polysaccharide (glucan) that allows them to adhere to each other forming plaque. Other sugars (glucose, fructose, lactose) can be digested by S. mutans to produce lactic acid. It is the combination of plaque and acid that leads to dental decay.

Spine in ankylosing spondylitis, X-ray Featured 8 Jan 2019 Print

Spine in ankylosing spondylitis, X-ray

Spine in ankylosing spondylitis. Coloured X-ray of a section through the thoracic spine of a 74-year-old male patient with ankylosing spondylitis, showing severe degeneration of the lower thoracic spine. Ankylosing spondylitis is an inflammatory disease that affects the joints between the spinal vertebrae in the back. The disorder usually begins with pain and stiffness in the lower back. As it progresses the pain and stiffness spread up the spine, causing increasing immobility. In severe cases curvature of the spine may occur and the spine may even become completely rigid due to fusion of the vertebrae. The cause is unknown. Treatment includes analgesic drugs and regular exercise
