Currently, there are 1407 species of microbes that include viruses, bacteria, fungi, protozoa, and helminthes. Out of these, 177 pathogens are considered as emerging or re-emerging. The re-emerging pathogen is one, which shows an increased incidence in an existing population due to interaction of multiple complex factors. There are many re-emerging pathogens, such as Brucella melitensis, Burkholderia mallei, B. pseudomallei, chikungynya virus, Coxiella burnetii, dengu virus, Francisella tularensis, Japanese encephalitis virus, Orentia tsutsugamushi, Salmonella typhimurium, Streptococcus pyogenese, S. suis, and Yersinia pestis, which carry significant morbidity and mortality, and are reported from developing as well as developed nations of the world. Among these, Streptococcus pyogenese, which belongs to Lancefield Group A Streptococcus, is a re-emerging bacterial pathogen, which affects humans as well as animals. Streptococci, which occur in chains, were first time observed in erysipelas and wound infections by Billroth in 1974. However, the name Streptococcus pyogenese was proposed in 1884 by Rosenbach who isolated the organism from suppurative lesions. Infection is worldwide in distribution but most commonly reported in temperate zones, such as France, Germany, Norway, Spain, Sweden, and UK. In temperate regions, about 20 % of school children may act as carrier of Group A Streptococcus during the season of winter and early spring. Globally, there are about 663,000 new cases and 163,000 deaths due to invasive S. pyogenes disease annually. In addition, 111 million cases of S. pyogenese pyoderma and 616 million cases of pharyngitis are reported worldwide each year. Recently, scarlet fever, the major clinical entity of S. pyogenese infection, has re-emerged in epidemic form causing significant morbidity and mortality. The outbreaks of scarlet fever are recorded from many countries, such as Canada, China, France, Hong Kong, Macau, Spain, Thailand, Vietnam, UK, and USA. These outbreaks were observed in mainly in day care centers, families, military camps, prisons, and schools.
