Streptococci (streptococci) – causes, symptoms, treatment of infection

Streptococci, also known as streptococci, are a type of bacteria that can cause various infections in humans. In this article, we will discuss the general characteristics of streptococci, how infection occurs, what diseases they can cause, and methods of treating these infections.

Streptococcus – general characteristics and classification

Streptococci are a group of Gram-negative bacteria that come in many different species. They are considered part of the natural bacterial flora in humans and may be present in the mouth, throat, nose, intestines and other parts of the body. Streptococci are spherical bacteria that often form chains, which gives them a distinctive appearance under a microscope.

The classification of streptococci is complicated and is based on various characteristics, such as the antigens on their surface. One of the most important division criteria is the division into groups A, B, C, etc. The most important from the point of view of human health are group A streptococci (Streptococcus pyogenes) and group B (Streptococcus agalactiae).

Streptococci – how does infection occur?

Streptococcal infections can spread in many different ways. The most common way of transmitting bacteria is through droplets, i.e. contact with the secretions of the nose and throat of an infected person. This may occur when sneezing, coughing, talking or touching infected surfaces.

Additionally, streptococci can also be spread through direct skin-to-skin contact or through infected objects such as towels or toys. There is also a risk of transmission of streptococci during sexual intercourse or from an infected mother to her newborn during delivery.

Streptococci – what diseases do streptococci cause?

Streptococci can cause a wide variety of illnesses, both mild and serious. Some of the most common streptococcal diseases include:

Pharyngitis: Group A streptococci are a common cause of acute pharyngitis, which is characterized by sore throat, fever, headaches, and weakness.

Strep throat: A more severe form of pharyngitis that can lead to complications such as throat abscesses.

Skin infections: Streptococci can cause skin infections such as cellulitis and impetigo. Symptoms include swelling, redness and pain of the skin.

Rheumatic fever: This is a rare complication of streptococcal infection that can lead to damage to the heart, joints and other organs.

Ear infection: Streptococcus can also cause ear infections, especially in children.

Streptococcus infections – treatment

Treatment of streptococcal infection depends on the type of infection and the stage of the disease. For mild throat infections, antibiotics such as penicillin are often used. In case of more serious infections, it may be necessary to hospitalize the patient and administer antibiotics intravenously.

It is also important to follow your doctor’s recommendations and complete the entire course of antibiotics, even if you feel better. Failure to complete treatment may lead to a recurrence of the infection or the development of bacterial resistance to antibiotics.

Your suggestions

If you suspect you have a strep infection or have questions about this type of bacteria, it’s always a good idea to consult your doctor. Your doctor will be able to properly diagnose the infection and prescribe appropriate treatment.
