Application

Penicillin G is a narrow spectrum antibiotic derived from Streptococcus pneumoniae. It is the drug of choice for groups A, B, C and G streptococci, nonenterococcal group D streptococci, viridians group streptococci, and non-penicillinase producing staphylococcus. The potassium salt has been used to study murosomes of staphylococci† and the penicillin-induced lysis of Streptococcus mutans†.

Actions biochimiques/physiologiques

Mode of Action: Inhibits bacterial cell wall synthesis.
Antimicrobial spectrum: Gram-positive bacteria

Conditionnement

1mu,10mu,100mu
