OXOID Microbiology Antibiotic Discs

• OXOID Microbiology Antibiotic Discs are small, circular pieces of filter paper that have been impregnated with an antibiotic solution.
• They are used to determine the susceptibility of bacteria to different antibiotics.
• The discs are placed on an agar plate that has been seeded with the bacteria to be tested.
• The antibiotic diffuses out of the disc and creates a concentration gradient around the disc.
• The bacteria will only grow in areas where the antibiotic concentration is below the minimum inhibitory concentration (MIC) for that bacteria.
• The size of the zone of inhibition around the disc is used to determine the MIC of the antibiotic for that bacteria.
• OXOID Microbiology Antibiotic Discs are available for a variety of antibiotics, including penicillin, streptomycin, and gentamicin.
• They are used in a variety of settings, including clinical laboratories, research laboratories, and industrial laboratories.

Here are some of the benefits of using OXOID Microbiology Antibiotic Discs:

• They are easy to use and can be used by laboratories of all sizes.
• They are relatively inexpensive.
• They are accurate and reproducible.
• They are a valuable tool for determining the susceptibility of bacteria to antibiotics.

If you are looking for a reliable and easy-to-use way to determine the susceptibility of bacteria to antibiotics, then OXOID Microbiology Antibiotic Discs are a good option to consider.

Here are some additional details about OXOID Microbiology Antibiotic Discs:

• The discs are made of filter paper that has been impregnated with an antibiotic solution.
• The antibiotic solution is typically made by dissolving the antibiotic in a solvent, such as water or ethanol.
• The discs are then dried and packaged.
• The discs are available in a variety of sizes, depending on the antibiotic and the concentration of the antibiotic solution.
• The discs are typically stored at room temperature.

To use the discs, you will need to:

1. Prepare an agar plate by pouring the agar into a petri dish and allowing it to solidify.
2. Seed the agar plate with the bacteria to be tested.
3. Place the antibiotic discs on the agar plate.
4. Incubate the plate at the appropriate temperature for the antibiotic being tested.
5. After the incubation period, measure the diameter of the zone of inhibition around each disc
