The Linezolid – 10 μg Antibiotic Disc – Bioanalyse is a paper disc impregnated with 10 micrograms of linezolid, an oxazolidinone antibiotic. It is used in the disc diffusion method of antimicrobial susceptibility testing to determine the susceptibility of bacteria to linezolid.

Linezolid is a broad-spectrum antibiotic, meaning that it is effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria. It is also effective against some bacteria that are resistant to other antibiotics, such as vancomycin-resistant Enterococcus (VRE).

Interpretation of results:

| Zone of inhibition | Interpretation | |—|—|—| | ≥ 20 mm | Susceptible | | 15-19 mm | Intermediate | | < 15 mm | Resistant |

It is important to note that the disc diffusion method is only a semi-quantitative method for testing the susceptibility of bacteria to antibiotics. For more accurate results, other methods such as broth microdilution or agar dilution should be used.

The Linezolid – 10 μg Antibiotic Disc – Bioanalyse is a valuable tool for the diagnosis and treatment of a wide range of serious bacterial infections, including:

• Pneumonia
• Skin and soft tissue infections
• Vancomycin-resistant Enterococcus (VRE) infections
• Nosocomial infections
• Other infections caused by multidrug-resistant bacteria

Limitations of the Linezolid – 10 μg Antibiotic Disc – Bioanalyse:

• The disc diffusion method is only a semi-quantitative method for testing the susceptibility of bacteria to antibiotics. For more accurate results, other methods such as broth microdilution or agar dilution should be used.
• The disc diffusion method is not able to detect all bacteria that are resistant to linezolid. For example, some strains of Staphylococcus aureus are resistant to linezolid, but they may not produce a zone of inhibition around a linezolid disc.
• The disc diffusion method can be affected by the type of agar plate used, the incubation temperature, and the inoculum density. Therefore, it is important to follow standardized procedures when performing the disc diffusion test.

Additional information about linezolid:

Linezolid is an oxazolidinone antibiotic. Oxazolidinone antibiotics are a class of broad-spectrum antibiotics that are reserved for the treatment of serious bacterial infections. Linezolid is a bactericidal antibiotic, which means that it kills bacteria.

Linezolid is a safe and effective antibiotic for most people. However, it is important to be aware of the potential side effects of linezolid before using it. Linezolid can cause side effects such as nausea, vomiting, diarrhea, and headache. In rare cases, linezolid can cause serious side effects such as myelosuppression (bone marrow suppression) and lactic acidosis.
