Streptococcus pneumoniae (S. pneumoniae) is a gram-positive bacterium that commonly causes a variety of infections, including those in the lungs, blood, and other parts of the body. Certain more invasive strains, such as Streptococcus pneumoniae serotype 19A (SPN 19A), can cause severe disease and can spread from person to person. Here is what you need to know about this type of bacteria.

What is SPN 19A?

SPN 19A is a serotype of S. pneumoniae. It's a strain of bacteria that causes severe types of infections, such as meningitis, bacteremia, and pneumonia. According to the Centers for Disease Control and Prevention, not all S. pneumoniae have the ability to cause invasive infections, and only SPN 19A has been seen to have this ability. This type of bacteria is commonly found in people suffering from chronic lung diseases such as cystic fibrosis, and in people with weakened immune systems.

The type of antibiotic used will depend on the severity of the illness, as well as any existing allergies or underlying medical conditions.

How Can It Be Prevented?

The best way to prevent SPN 19A is to practice preventive measures such as washing your hands frequently, avoiding contact with people who are ill, avoiding touching your face, and getting vaccinated against S. pneumoniae. Vaccines are available for healthy adults age 19 and up, and can help protect against SPN 19A and other types of bacteria.
