Oxacillin

Oxacillin sodium (trade name Bactocill) is a narrow spectrum beta-lactam antibiotic of the penicillin class. It has been used particularly in the treatment of Staphylococcus aureus infection, and resistant strains may be called oxacillin-resistant Staphylococcus aureus (ORSA). It is not in use in the UK (which only uses it for laboratory identification of MRSA and to detect penicillin resistance in Streptococcus pneumoniae).

Is very active against gram negative organisms such as E.coli (possibly incorrect stetement. need to verify).
