The Levofloxacin – 5 μg Antibiotic Disc – Bioanalyse is a paper disc impregnated with 5 micrograms of levofloxacin, a fluoroquinolone antibiotic. It is used in the disc diffusion method of antimicrobial susceptibility testing to determine the susceptibility of bacteria to levofloxacin.

Fluoroquinolone antibiotics are a broad-spectrum class of antibiotics that are effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria. Levofloxacin is used to treat a variety of infections, including:

• Pneumonia
• Skin and soft tissue infections
• Urinary tract infections
• Sinus infections
• Bone and joint infections
• Anthrax

Interpretation of results:

| Zone of inhibition | Interpretation | |—|—|—| | ≥ 15 mm | Susceptible | | 13-14 mm | Intermediate | | < 13 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 Levofloxacin – 5 μg Antibiotic Disc – Bioanalyse is a valuable tool for the diagnosis and treatment of a wide range of serious bacterial infections. However, it is important to be aware of the potential side effects of levofloxacin before using it. Levofloxacin can cause side effects such as nausea, vomiting, diarrhea, and headache. In rare cases, levofloxacin can cause serious side effects such as tendonitis, seizures, and allergic reactions.

Limitations of the Levofloxacin – 5 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 levofloxacin. For example, some strains of Pseudomonas aeruginosa are resistant to levofloxacin, but they may not produce a zone of inhibition around a levofloxacin 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 levofloxacin:

Levofloxacin is a fluoroquinolone antibiotic. Fluoroquinolone antibiotics are a class of broad-spectrum antibiotics that are effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria. Levofloxacin is a bactericidal antibiotic, which means that it kills bacteria.

Levofloxacin is a safe and effective antibiotic for most people. However, it is important to be aware of the potential side effects of levofloxacin before using it. Levofloxacin is not recommended for people who are allergic to fluoroquinolone antibiotics or for people with kidney problems.
