What are the two types of Streptococcus pneumoniae?
Streptococcus pneumoniae can be differentiated from the viridans streptococci, some of which are also alpha-hemolytic, using an optochin test, as S. pneumoniae is optochin-sensitive. S….

What does Streptococcus pneumoniae cause?
Streptococcus pneumoniae is the most common cause of ear infections (otitis media), sepsis (blood infection) in children as well as pneumonia in immunocompromised individuals and the elderly. Streptococcus pneumoniae is considered “invasive” when it is found in the blood, spinal fluid or other normally sterile sites.
How many strains of Streptococcus pneumoniae are there?
There are more than 90 different strains of Streptococcus pneumoniae (S. pneumoniae) bacteria (known as serotypes), some of which cause more serious infection than others.
What is the common name for Streptococcus pneumoniae?
Pneumococcal [noo-muh-KOK-uhl] disease is a name for any infection caused by bacteria called Streptococcus pneumoniae, or pneumococcus. Pneumococcal infections can range from ear and sinus infections to pneumonia and bloodstream infections.
Who is at risk for Streptococcus pneumoniae?
Adults 65 years or older are at increased risk for pneumococcal disease. Adults of all ages are also at increased risk for pneumococcal disease if they have: Alcoholism. Chronic heart, lung, kidney, or liver disease.
What is the best treatment for Streptococcus pneumoniae?
Penicillin and its derivatives are inexpensive effective antibiotics for treating pneumococcal infections when they are used against susceptible isolates. Penicillins can be administered orally or parenterally and work by inhibiting cell wall synthesis.
What are the symptoms of Streptococcus pneumoniae?
Symptoms can include fever, cough, shortness of breath, chest pain, stiff neck, confusion, increased sensitivity to light, joint pain, chills, ear pain, sleeplessness, and irritability. In severe cases, pneumococcal disease can cause hearing loss, brain damage, and death.
How long does it take to recover from Streptococcus pneumoniae?
However, most people recover from pneumonia in about a week. Bacterial pneumonia usually starts to improve shortly after starting antibiotics, while viral pneumonia usually starts to improve after about three days. If you have a weakened immune system or a severe case of pneumonia, the recovery period might be longer.
What antibiotic is best for strep pneumonia?
– Otitis media. In cases of otitis media, S. – Sinusitis. Acute purulent sinusitis is caused by the same organisms as acute otitis media; thus, S. – Acute bronchitis. – Pneumonia. – Complications.Empyema, the most common infectious complication of pneumococcal pneumonia, occurs in approximately 2% of cases. – Meningitis. – Other infections.
What are symptoms of Streptococcus pneumonia?
Respiratory Difficulty. The small air sacs of the lungs,the alveoli,become infected and pus builds up in the small airway sacs.
What happened to the streptococci?
What happened to the streptococci: overview of taxonomic and nomenclature changes. Since the division of the Streptococcus genus into enterococci, lactococci, and streptococci in 1984, many changes in the nomenclature and taxonomy of the Streptococcus genus have taken place. The application of genetic comparisons has improved the proper classification of the different species.
Is streptococcal pneumonia contagious?
These bacteria can affect anywhere from a small portion of one lung to widespread areas in both lungs. 1. Depending on the strain of bacteria causing pneumonia, you may be contagious anywhere from a few days to a few weeks. One of the most common strains known for causing pneumonia is called pneumococcal.
