Streptococcus Pdf Streptococcus Biology In the normal human the skin is an effective barrier against invasive streptococci, and nonspecific defense mechanisms prevent the bacteria from penetrating the superficial epithelium of the upper respiratory tract (cilia movement, coughing, sneezing and epiglottal reflexes). The group a streptococcus (gas) (streptococcus pyogenes) is among the most common and versatile of human pathogens. it is responsible for a wide spectrum of human diseases, ranging from trivial. Streptococci are gram positive, nonmotile, nonsporeforming, catalase negative cocci that occur in pairs or chains. older cultures may lose their gram positive character. most streptococci are facultative anaerobes, and some are obligate (strict) anaerobes. most require enriched media (blood agar). Immunological cross reactions among cap sular polysaccharides of pneumococci and of a and nonhemolytic streptococci have been identified by a number of investigators.
