Acute Morphology of Streptococcus pyogenes Essay -- Medical Disease Ba
Acute syllable structure of Strepto coccus pyogenesAbstract streptococcus pyogenes is a gram positive coccus bacterium that is extremely common bacteria. This bacterium is part of group A streptococci, which meant that it has a certain type of polysaccharide antigen on its cell surface. It is commonly known as pharyngitis, or strep throat and produces over xx exotoxins. Even though this bacterium has been around for thousands of years it still has a susceptibility to penicillin and there have only been a few cases of resistance.strep pyogenes is a gram positive bacteria that is associated with multiple types of diseases. Streptos means a chain of links and coccus means a round object. unneurotic this describes the shape of Streptococcus pyogenes, a round chain of ten or more cocci, each measuring 0.5 to 0.75 m in diam. This bacterium suffer cause scarlet fever, streptococcal pharyngitis and erysipelas in humans. It is identified gener in ally by its ability to create -haemolys is in blood agar plates. streptococcus can be separated into groups by a polysaccharide antigen that is involved inside the cell wall. The groups are labeled by the letters ranging from A to R, each group represents a different type of organism that it in the main infects. Group A is mainly pathogenic to humans, while group B is found in cattle. Groups C to R infect animals of lesser complexity. Streptococcus pyogenes is part of group A, which means that the polysaccharide antigen is composed of rhamnose and N-acetylglucosamine and its main soldiery is in humans.The morphology of S. pyogenes is a chain of cocci that are commonly in groups of ten and each cocci range in diameter from 0.5 to 0.75 m. They are nonmotile, which means that they2have no form of moveme... ...agar plates. S. pyogenes produces some extracellular products, they are called streptococcal pyrogenic exotoxins and are classified into tercet serotypes, A-C. SPE B is the most unique of the three and is respons ible for multiple diseases, including unhealthful shock syndrome. This bacteria does have a weak point, almost all streptococci are susceptible to penicillin.7Works CitedChristie, A. B. (1987). Infectious Diseases (Vol. 2, quaternate ed.).
