Flashcards

S. pneumonia Transmission

The primary mode of transmission for S. pneumonia is from person to person, typically through respiratory droplets.

S. pneumonia Virulence Factor

Lipoteichoic acid is a virulence factor associated with S. pneumonia, contributing to its ability to adhere to host cells and evade the immune system.

S. pneumonia Infection

Erysipelas is a skin infection caused by S. pneumonia, characterized by red, painful, and swollen skin.

Penicillin-Allergic Treatment

For penicillin-allergic patients with S. pneumonia infections, a combination of penicillin and gentamycin is often recommended.
