Oxoid Optochin Antibiotic Discs

Oxoid Optochin Antibiotic Discs – Accurate Identification of Streptococcus pneumoniae

Oxoid Optochin (P) Discs are precision antibiotic susceptibility test discs designed for in vitro differentiation of Streptococcus pneumoniae from other alpha-hemolytic streptococci. These discs are widely used in clinical microbiology laboratories for accurate and rapid bacterial identification.

What Are Oxoid Optochin Discs?

Oxoid Optochin discs are filter-paper discs impregnated with optochin (ethylhydrocupreine hydrochloride), an antibiotic that selectively inhibits Streptococcus pneumoniae. During disc diffusion testing, the disc is placed on an agar plate inoculated with the bacterial sample. A zone of inhibition around the disc confirms the presence of S. pneumoniae, helping differentiate it from other alpha-hemolytic streptococci such as Viridans streptococci.

Key Features

• High-Quality Laboratory Standard: Manufactured by Oxoid for consistent, reproducible results.
• Selective Identification: Specifically targets Streptococcus pneumoniae for accurate differentiation.
• Easy to Use: Ready-to-use discs suitable for standard agar plate testing.
