redOrbit Staff & Wire Reports - Your Universe Online Two types of Streptococcus bacteria responsible for many sore throats and other, more serious infections persist on surfaces far longer than previously believed, according to new research appearing in Thursday’s edition of the journal Infection and Immunity. Previous studies have determined that the bacteria in question, Streptococcus pneumoniae and Streptococcus pyogenes, are unable to live for long outside of the human body....

Scarlet fever has revealed unusual high infect rate in HK this year. So far, 466 children were infected and 2 of them dead. Scarlet fever is caused by Streptococcus pyogenes, a gram-positive pathogen that can be transmitted viaskin wound and airborne droplet.  According to the guidance of Hong Kong Center for Disease Control (HK CDC), Hong Kong University (HKU) and their partners today released the draft genome sequence of the S. pyogenes strain that was isolated from a scarlet fever...

Bacteria often attack with toxins designed to hijack or even kill host cells. To avoid self-destruction, bacteria have ways of protecting themselves from their own toxins. Now, researchers at Washington University School of Medicine in St. Louis have described one of these protective mechanisms, potentially paving the way for new classes of antibiotics that cause the bacteria's toxins to turn on themselves. Scientists determined the structures of a toxin and its antitoxin in Streptococcus...

Researchers from HZI are investigating the development of novel therapies to make the old immune system young again By comparing the immune responses of both, young and old mice, to bacterial infection they found that the number of macrophages, one of the major cell populations involved in the elimination of infecting bacteria, decreases rapidly in aged mice. This decline in the number of fighters and the associated weakness of the immune defense may be responsible for the age-associated...

Faster method to create antibodies for disease research British scientists are pioneering a new technique to produce large numbers of antibodies quickly and reliably to help the study of dangerous bacteria. The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), is a critical area for study as bacteria such as streptococcus cause deadly blood infections and 'flesh eating bug disease'. Traditional methods of producing antibodies for research are slow and...

Streptococcus pyogenes is a spherical, Gram-positive bacterium is the cause of Group A streptococcal infections. It displays streptococcal group A antigen on its cell wall. When it is cultured on blood agar plates it produces large zones of beta-hemolysis. They are catalase-negative and in ideal conditions it has an incubation period of about 1-3 days. It is an infrequent part of the skin flora. It is the cause of many important human diseases, ranging from mild superficial skin infections...
