IN the NEWS - Prince of Persia Returns with an Old Cocktail - New Mixture

For we know that the whole creation groaneth and travaileth in pain together until now. Romans 8:22
 
"Scientists are sounding the alarm that, once Covid-19-related social distancing ends, the world’s children may face a new pandemic from a mutated old enemy which was once a leading cause of death for kids in the Western world.
 
Scarlet fever, caused by the bacteria streptococcus pyogenes and considered as deadly as Covid-19, has made a recent resurgence in the UK, China, South Korea and Vietnam, with cases recorded in Australia and even New Zealand. UK case numbers have also quadrupled in recent years. 

Scarlet fever symptoms include chills, fever, sore throat, abdominal pain, a swollen tongue, red rash, and peeling skin.

However, scientists now think that so-called “supercharged bacterial clones” have been behind the latest waves of the disease, which boasts a fatality rate of 15-20 percent.

 Clues about the mysterious resurgence in a disease that was brought to the brink of extinction were found in the genome of a northeast Asian strain of A strep, or streptococcus pyogenes, one of the bacterial strains responsible for scarlet fever

Antigens are any substance which stimulates an immune response, such as antibodies. Superantigens produce an excessive and problematic immune response. 

Hidden within the strain of A strep behind the recent wave of scarlet fever outbreaks was a superantigen which gave pathogens previously unseen access to the host’s cells.

This entirely new means of inflicting damage diverges greatly from the historical strain that ravaged Western Europe in the past.

Essentially, the toxins which infected streptococcus pyogenes afforded it new powers of infection, making it better at colonizing its host and outperforming other strains, courtesy of a process known as horizontal gene transfer. Stolen genes like these can make pathogens more infectious, more deadly and more resilient."
