From a strep throat to a deadly flesh eating virus, it’s hard to believe the same bacteria are responsible for both diseases. The Textbook of Bacteriology states 5 to 15% of normal people carry these bacteria in the respiratory tract on a...
The bacterium Streptococcus pyogenes is a significant cause of human disease, most often associated with infections of the respiratory tract, blood, and skin. It is estimated that streptococcus results in about 10 million mild throat and skin...
A number of common skin conditions can cause big bumps on the scalp. While unsightly, many of these conditions remain benign. However, in some cases these bumps may indicate the presence of serious health complications such as skin cancer. Speak...
Strep throat is caused by the Streptococcal bacteria S. pyogenes, according to the Mayo Clinic website. Most sore throats are caused by viruses, but the symptoms of strep throat usually are much more severe. Antibiotics are necessary to kill S....
Strep A and strep B, or Streptococcus pyogenes and Streptococcus agalactiae respectively, are closely related microorganisms with several characteristics in common. First, they both produce beta-hemolysis, which means the organisms contain...
Necrotizing fasciitis, also known as flesh-eating bacteria, is caused by Streptococcus pyogenes as well as aerobic and anaerobic organisms. Streptococcus pyogenes produces toxins that destroy the skin and its underlying tissue in addition to...
Skin problems affect many people at some point in their lives. There are a number of common skin problems such as acne, eczema and psoriasis. Problems may also occur when skin becomes damaged or broken, as bacterial infections may lead to skin...

Infantigo, or "Impetigo," as it's properly termed, occurs when either staphylococcus aureus (staph) or streptococcus pyogenes (strep) bacteria enter the bloodstream. The disease is commonly known as "infantigo" because it most often occurs in...
Tonsillitis is an inflammation of the tonsils, two pieces of lymphoid tissue on either side of the throat. The tonsils are the immune system's first line of defense, filtering bacterial and viral organisms that enter the mouth. The tonsils can...
Tonsillitis is a medical condition characterized by an inflammation of the tonsils. The tonsils are lymphoid organs that filter and trap bacterial and viral organisms. As a result of their role in pathogenic filtration, the tonsils are...
