Typically, a prosthetic arm or leg is made from a strong and durable but lightweight material such as carbon fiber, covered with foam padding (for comfort) or flesh-colored plastic. The weight of prosthetic limbs is a very important factor. We don't notice how much our limbs weigh because they feel so natural and seem to move themselves.
Scientific Name for Strep Throat. Strep throat is the most common type of bacterial throat infection; it is caused by group A streptococcus bacteria (GAS for short). The scientific name for strep throat bacteria is Streptococcus pyogenes. This throat infection is most frequently diagnosed during the late fall, winter, and early spring. Symptoms can include fever, white patches of pus on the back of the throat, and a red and painful throat that begins suddenly.
The Streptococcus species are clustered into four groups: pyogenic, oral, anaerobic and other. Pyogenic streptococci are pathogens that are associated with pus formation. Most of these species are Beta hemolytic and Streptococcus pyogenes is part of this group.Oral streptococci inhabit the oral cavity and upper respiratory tract of humans and other animals, but other than habitat are not simliar.he most common infection from Streptococcus pyogenes is impetigo, a superficial cutaneous infection common to children characterized by crusty legions and vesicles surrounded by a red border. Erysipelas-an acute infection and inflammation of the dermal layer of the skin.
