Metronidazol Antibiotic Disc – Himedia
The Metronidazole Antibiotic Disc by HiMedia is a valuable laboratory tool used in antimicrobial susceptibility testing to determine the susceptibility of bacterial pathogens to metronidazole, which is an antibiotic and antiprotozoal medication.

Key Features of the Metronidazole Antibiotic Disc – HiMedia:
- Antimicrobial Susceptibility Testing (AST): The Metronidazole Antibiotic Disc is an essential component of AST methods, such as the disk diffusion method. It allows laboratories to evaluate the sensitivity of bacterial isolates to metronidazole, providing critical information for guiding antibiotic therapy decisions.
- Wide Antimicrobial Spectrum: Metronidazole is known for its broad-spectrum activity against a range of anaerobic bacteria and certain protozoa, including Trichomonas vaginalis, Giardia lamblia, and Entamoeba histolytica. It is effective against a wide variety of susceptible microorganisms.
- Standardized Disc Potency: The disc comes with standardized potency, ensuring consistent and reliable results across different laboratories and testing procedures.
- Compatibility with AST Methods: The Metronidazole Antibiotic Disc is designed to be compatible with standard AST methods used in clinical microbiology laboratories, making it easy to incorporate into existing testing protocols.
- Ready-to-Use: The disc is ready to use, eliminating the need for additional preparation steps in the laboratory. This saves time and allows for efficient testing of bacterial isolates.
- Clear Zone of Inhibition Interpretation: After incubation, the presence of a clear zone of inhibition around the disc indicates that the bacteria are susceptible to metronidazole. The absence of such a zone indicates resistance, guiding clinicians towards alternative treatment options.
- Laboratory Safety: The Metronidazole Antibiotic Disc is designed to meet safety standards, ensuring that laboratory personnel can handle the discs safely and securely.
Metronidazole is commonly used to treat various infections, including anaerobic bacterial infections in the gastrointestinal tract, gynecological infections, and certain parasitic infections. It is also used in combination with other antibiotics for the treatment of Helicobacter pylori infections associated with peptic ulcers.
