Upper Respiratory Tract Infection caused by susceptible streptococci

Upper Respiratory Tract Infection Caused by Susceptible Streptococci

An upper respiratory tract infection (URTI) is an infection of the throat, nose, sinuses, Eustachian tubes, or upper airways caused by certain types of bacteria and viruses. One type of bacteria linked to URTIs is susceptible streptococci. Streptococcal infections can range from mild to serious, and can affect people of any age. It’s important to be aware of the symptoms and proper treatments.

Types of Streptococci

Streptococcus is a genus of Gram-positive bacteria that are spherical in shape and usually clustered together in the form of a chain. While streptococci are found widely throughout nature, some are known to specifically cause URTIs. These include:

  • Streptococcus pyogenes
  • Streptococcus pneumoniae
  • Streptococcus viridans

Symptoms of URTI

Most URTI symptoms resemble those of the common cold, and usually start two to four days after being exposed to the bacteria. The most common symptoms include:

  • Sore throat
  • Nasal congestion
  • Runny nose
  • Cough
  • Mild headache
  • Decreased appetite
  • Slight fever
  • Sneezing
  • Hoarseness

Treatments for URTI

The goal of treatment is to reduce or eliminate symptoms and to prevent the infection from spreading further. The treatment for URTI caused by susceptible streptococci will depend on the strain and severity of infection, as well as the age and health of the patient. Generally, treatment may include:

  • Antibiotics: These are prescribed to treat bacterial infections and help to eliminate the streptococcal bacteria.
  • Fluids: Encouraging the patient to drink plenty of fluids can help reduce symptoms by thinning mucus.
  • Rest: Taking time to rest can help the body heal and may reduce the spread of infection.
  • Over-the-counter medications: These can be used to relieve some of the symptoms of URTI, such as fever or pain.


Upper respiratory tract infections (URTI) can be caused by a variety of bacteria, including susceptible streptococci. It is important to be aware of the signs and symptoms of URTI, and to seek medical help if the infection becomes severe or does not go away with home treatment. With the right treatment, URTI caused by susceptible streptococci can be managed effectively.
