Streptococcus is a bacterial infection that can cause sepsis, a serious medical condition where an infection affects the bloodstream or other tissues. Streptococcus pyogenes is a common pathogenic species that can cause strep throat and sepsis. Streptococcal species can bypass the immune system and cause antibiotic resistance. Sepsis is characterized by the spread of bacteria into tissues or the bloodstream, causing an inflammatory response that can result in organ failure and death. Treatment includes intravenous antibiotics and nutrients.
Streptococcus is a generic term for an infection caused by a bacterium of the genus Streptococcus. Sepsis is a serious medical condition in which a microbial infection affects the bloodstream or spreads to other tissues. Many different microbes can cause sepsis, including streptococcal species. Streptococcus and sepsis, therefore, may be closely related.
Streptococcus-type infections typically involve the presence of Streptococcus species, although the term can sometimes refer colloquially to diseases with similar appearances. Streptococcus pyogenes is a common pathogenic species and the condition known as strep throat, for example, is one of the diseases it causes. While a sore throat is usually a fairly minor problem that isn’t dangerous to your health, strep infections can be life threatening in some cases.
Streptococcus bacterial cells are all spherical in shape under the microscope and tend to arrange themselves in chains or in pairs. They can live in environments with or without the presence of oxygen, so they can adapt to many different body tissues, such as the lungs or blood. There are many different species in the group, and not all have the same virulence in humans. Some species, such as S. pneumoniae, prefer to infect the lungs, and S. mutans is more likely to infect the teeth and cause tooth decay. In the context of strep throat and sepsis, Streptococcus pyogenes is a common offender as it has the ability to break down human blood for food and is easy to catch through aerosol droplets.
Many types of bacteria can cause sepsis, as can some fungi. Mostly, however, sepsis is of bacterial origin. The condition occurs as a complication of an existing infection. In the case of strep and sepsis, the initial infection could be in a skin wound, from a medical implant, or from a site such as the lungs. Organ transplant operations can also introduce streptococcus and sepsis to the patient through environmental contamination.
Most healthy people have immune systems strong enough to fight off strep invasions, but sepsis is much more likely in people who are older or have suppressed immune systems. Streptococcal species have various ways in which they can bypass the defenses of the immune system. These include the production of toxins, which coat the cell with a variety of molecules so that the immune system does not recognize the bacterium or becomes a tool to enter host cells. Antibiotic resistance is another concern for medical professionals regarding strep species.
Instead of affecting only one part of the body, sepsis is characterized by the spread of the bacteria into tissue or through the blood. The immune system recognizes these widespread infections and initiates the inflammatory response to fight the invading cells. One downside of an intense inflammatory response is the increased risk of tiny blood clots that can block vital nutrients from reaching your organs. The affected organs can then fail and the circulatory system can become ineffective at pumping blood, resulting in death. Treatments for sepsis include intravenous antibiotics and nutrients.
