a commonly used penicillin compound; it comprises 85% of the penicillin salts: sodium, potassium, aluminum, and procaine, with the latter exerting prolonged action on intramuscular injection, because of limited solubility. An antibiotic obtained from the mold Penicillium chrysogenum used orally and parenterally; primarily active against gram-positive staphylococci and streptococci; destroyed by bacterial β-lactamase.

pyogenes is usually susceptible to benzyl penicillin, ampicillin, gentamicin, and macrolides and resistant to trimethoprim/sulfamethoxazole, streptomycin, and tetracyclines (10).
One interesting finding in this study was that isolated Enterococcus gallinarum and all four isolated Enterococcus faecalis were sensitive to both Benzyl penicillin and Ampicillin although all isolated Enterococcus faecium were resistant to both of the drugs.
All isolates of Enterococcus faecalis and Enterococcus faecium were sensitive to Vancomycin and Linezolid but Enterococcus gallinarum isolate inspite of being Benzyl penicillin sensitive, was Vancomycin resistant (MIC value is [greater than or equal to] 32 [micro]g/ml).
