Testing Penicillin-G aganst several strains of bacteria was part of an
experiment I asked some students to do. 
In their reports some of the students mention that P-G is supposed to be
active against G+ bacteria, which is obvious, but in addition it's supposed
to be active against G neg. cocci. 
Anyone having an explanation? 
Personally I do only have teoretical knowledge about P-G, and my knowledge
about differences between cellwalls of cocci and bacilli is scarse. Could
anyone explain, please.
