|Description:||This illustration depicts a three-dimensional (3D) computer-generated image of a group of erythromycin-resistant Group-A Streptococcus (GAS), also known as S. pyogenes, bacteria, which were arranged in chains. The artistic recreation was based upon scanning electron microscopic (SEM) imagery. If you look carefully, you’ll be able to see a number of these organisms undergoing the process of cell division along the long axis of their respective chains.|
Group A Streptococcus is a bacterium often found in the throat and on the skin. People may carry group A streptococci in the throat or on the skin and have no symptoms of illness. Most GAS infections are relatively mild illnesses such as "strep throat," or impetigo. Occasionally these bacteria can cause severe and even life-threatening diseases.
