The specialists at Rockefeller University performed a complicated medical research which ahs as main result, the identification of another possible cause of strep throat: a bacteriophage. The so far neglected microorganism that eats bacteria seems to cause not only strep throat but also many other conditions of bacterial nature.
This condition's main cause are Group A beta-hemolytic bacteria, a type belonging to the large family of streptococcal bacteria. Throat infections may also be caused by groups C and G strep bacteria. The diseases generated by streptococcus bacteria are more or less serious. Strep throat is not commonly considered a serious condition.
Strep throat is caused by a bacterial infection with Streptococcus Pyogenes, or group A hemolytic streptococcus.
Streptococcal bacteria spread, when someone coughs or sneezes and it also affects people around that person, because it has a contagious character. It also may be picked up from any surface and then - transmitted or transferred to the mouth or nose; such surfaces are a doorknob, bathroom and kitchen objects.
