How many types of pneumococcal bacteria are there?

How many types of pneumococcal bacteria are there?

Pneumococcal disease includes a wide range of infections caused by different types of pneumococcus bacteria (Streptococcus pneumoniae). There are over 90 different types of these bacteria, and vaccines have been produced to protect against the types that cause the most disease.

What are 2 types of pneumococcal bacteria?

Types

• Bacterial pneumonia: Many bacterial strains can cause pneumonia, but the most common is Streptococcus pneumoniae (S.
• Viral pneumonia: Viral causes of pneumonia include the respiratory syncytial virus and influenza types A and B.

What is serotype in vaccine?

A serotype is defined as one which either exhibits no cross-reaction with others, or shows a homologous/heterologous titer ratio greater than 16 (in both directions). From: Virus Taxonomy, 2005.

What is the most common type of pneumococcal disease in adults?

Pneumococcal pneumonia (lung infection) is the most common type of bacterial pneumonia. Death rates for pneumococcal pneumonia in adults are 15-20 percent and as high as 40 percent among elderly patients.

What is the difference between Streptococcus pneumoniae and pneumococcal pneumonia?

What is pneumococcal disease? Pneumococcal disease is caused by bacteria called Streptococcus pneumoniae (pneumococcus). People with pneumococcal disease can spread the bacteria to others when they cough or sneeze. Symptoms of pneumococcal infection depend on the part of the body affected.

What serotype is Prevnar 13?

PCV13 (Prevnar13®) includes purified capsular polysaccharide of 13 serotypes of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 19A, 19F, 18C, and 23F) conjugated to a nontoxic variant of diphtheria toxin known as CRM197.

What is the difference between PCV 13 and PPSV23?

PCV13 (pneumococcal conjugate vaccine) protects against 13 of the approximately 90 types of pneumococcal bacteria that can cause pneumococcal disease, including pneumonia, meningitis, and bacteremia. PPSV23 (pneumococcal polysaccharide vaccine) protects against 23 types of pneumococcal bacteria.

What is the difference between strain and serotype?

Serotypes are different from strains, which have been described as single isolates from pure cultures or simply as distinct isolates of specific phenotypic/genotypic traits (or both). A serotype if also different from genotype which entails the set of genes (a heritable genetic characteristic) of an organism.

What is a viral serotype?

A serotype or serovar is a distinct variation within a species of bacteria or virus or among immune cells of different individuals. These microorganisms, viruses, or cells are classified together based on their surface antigens, allowing the epidemiologic classification of organisms to the subspecies level.

What are the four classification of pneumonia?

A pneumonia infection is classified based on how it is acquired and can be categorized into community-acquired, hospital-acquired, healthcare-acquired, or aspiration pneumonia.

What is the difference between PCV13 and PPSV23?

What is the difference between pneumonia and pneumococcal?

Pneumonia can be classified into bacterial, viral, fungal or aspiration as the cause. Pneumococcal pneumonia specifically refers to a pneumonia caused by the Strep pneumo bacteria,” Dr. Jenkins says.

What is the difference between pneumonia and pneumococcal pneumonia?

What type of pneumonia is most common?

The most common type of bacterial pneumonia is called pneumococcal pneumonia. Pneumococcal pneumonia is caused by the Streptococcus pneumoniae germ that normally lives in the upper respiratory tract. It infects over 900,000 Americans every year.
